            @* These four were one panel called "Session", which is a container word rather
               than a name: it held the standings, a waiting list, the hand log and the
               save/load/reset buttons — a topic, a task, a log and three utilities, which
               is four kinds of thing under one label. It measured at 1206px and 103
               elements, and "The table itself" was 1052px down inside it, so reaching
               Reset table meant opening a panel called Session and scrolling past the
               money and the log to get there.
               Each panel is named for the thing a dealer came looking for, and the
               subheads that used to do that job are gone, because the summary says it
               now. They are in the order of a night: set the table up, watch the money,
               fill the seats, look back at a hand — and, last and apart from the rest,

            @* Last, and on its own, because everything in it is about the night as a whole

               1052px down, which hid it but also meant nobody could find it on purpose.

   and put Resolve Pot underneath itself, and the raise pad's amount field at `100%`

+   It used to do that with `padding-right: 22px`, which takes the chip's width off every
   line of the name — and the chip is on one of them. Measured at 1280x900: the name box
   is 78px wide, "Christopher" is 66px and fits, and on the seat holding the button it
   was cut to 56px and broke as "Christop / her". Mid-word, and no hyphen (see below).
   The button moves every hand, so that is a player whose name reads properly for four
   hands and comes apart on the fifth. On a Pixel 7 it went to three lines and the clamp
   ate the end of it.
   A float is what indents only the lines it sits beside, which is the whole of the
   problem. Line one gets 56px and the rest get 78, so a name too long to fit beside the
   chip drops below it whole instead of being broken to fit next to something that isn't
   there. A short name still sits up beside the chip exactly as it did.
   The padding stays for the crowded ring, and it has to. A tight puck gives the name one
   line on purpose — see `.seatsTight .seatPuckName` — and one line has nowhere to move
   to, so the only way to keep it off the chip there is to make the line shorter. Trying
   the float on both cost a whole sweep to find out: with two lines granted, the name
   dropped below the float onto a second line that the chip's lower half was still
   sitting on, and the audit called it at every viewport in the list.
   So the float is for the ring that has room for two lines, and the padding is for the
   one that doesn't. Two rules, matching the two regimes the puck already had. */

   working: it breaks a word to fit the short line rather than letting it move past the
   float to the long one, which is the whole manoeuvre.
   Measured, at the name-box widths a roomy button seat gets:
     78px (desktop, iPad)  "Christopher"  was 2 lines of 54+12   now 1 line of 66
     78px (desktop, iPad)  "Katarzyna"    was 2 lines of 49+6    now 1 line of 56
   The float is one line tall, which is the height it has to be: tall enough to cover the
   chip's reach into the name — the chip's bottom edge is 26px down and the name's first

   The pill was worse than empty space. It has a background, a pill radius and side
   padding, so with no text it painted an 8x11px green lozenge in the middle of the puck

   every seat that stood for nothing. Nine of those is not a table, it is a rash.

   padding take it from 15px to 12, which clears the name at 5px of overhang instead of
   9 — and four pixels off what every seat is charged is a whole size step of puck back.

+
       "Where the room isn't the binding constraint — 390x844 and up — nothing changes
       and the table stays round" is what this used to say, and it was true and it was
       the bug. A square felt on a portrait phone can never be taller than it is wide,
       so on every phone with room to spare the surplus was measured, published, and
       dropped: 522px of room under a 366px felt on an iPhone 14, 638 under 406 on a Pro
       Max. Nothing was wrong with the arithmetic. The shape simply refused the answer.
       So the preferred shape is an oval standing up, and the cap above stays to stop it.
       A phone is a portrait screen and this is a table seen from above — the wide layout
       has been an oval lying down (0.72) all along, and the two are the same decision
       made twice. What it buys is rim: twelve seats at 390x844 went from a 44px puck
       with five names clipped to 66px with one, and five seats went from three clipped
       to none.
       1.5 is where the sweep stops paying. 1.6 and 1.7 measured byte-identical to each
       other on every phone, because by then the room is the binding constraint again;
       between 1.35 and 1.5 the twelve-seat ring on a Pixel 7 goes from one clipped name
       to none. The three smaller phones are room-bound at any cap at all and measured
       identical from 1.15 to 1.7, so this cannot regress them.
       It was tempting to pick a lower number and claim it bought stillness — a felt
       whose height *is* --feltRoomPx moves every time the bar does. That claim was
       written here and it was wrong: the bar's growth was measured at 125px resting,
       233px with six players all in, and 341px with twelve and their nine side pots
       listed. 216px of growth is more slack than any phone has at any aspect ratio, so
       there is no number here that buys stillness. renderSeats() is
       already told when the room changes, which is the thing that actually holds the
       chips on their seats, and this rule stops trying to.
       A floor under the max-height was tried here and taken out again, which is worth
       writing down because it looks obviously right. The worry was that max-height has
       no lower bound, so a tall enough bar presses the felt flat; the fix was to floor
       it at 72cqw, the wide layout's own oval, so the worst a phone could do was arrive
       at the shape the desktop already has.
       It made things worse. Twelve players all in with nine side pots is the tallest the
       bar gets — 341px — and at 360x640 that leaves 142px of room. Floored to 242 the
       felt keeps its shape and puts five of the twelve seats behind the bar; unfloored
       at 142 it is a flat table with all twelve of them visible. Same on an iPhone SE,
       three seats against none. A covered seat is the fault this whole measurement
       exists to prevent, and a flat table is only ugly.
       The slit the floor was defending against was never reachable either. It came from
       forcing --feltRoomPx to 10px by hand; the real floor is FELT_FLOOR_PX at 96, and
       the worst any of these phones actually publishes is 142, which lays out fine.

 /* ---------- A phone on its side: the bar goes beside the table ----------
   Everything above spends its effort dividing one column of height between a table and
   a bar, on the screen that has the least height in the world. Measured at 640x360
   mid-hand, the split comes out: 70px of header, 85px of felt, 205px of bar. The felt
   is 529x85. Two rows of seat pucks 55px tall have to fit in 85px of it, which they
   cannot, so seven of the nine finish past the rail — up to 17px of puck floating on
   the page. That is 96 of the 98 offenders the layout audit finds anywhere.
   No amount of shrinking fixes it, because the shortage is not in the table. A phone
   on its side is 640x360: short of height and swimming in width. The bar is 205px tall
   and 529 wide to hold three buttons and a status line, and it is taking that height
   from the one element on the page that needs height.
   So it moves. In landscape the bar becomes a right-hand rail, the table takes the
   whole column beside it, and the felt goes from 529x85 to roughly 420x270 — an actual
   oval, with room for two rows of pucks and a gap between them.
   The rail is also where the hand already is. This is the layout every mapping and
   drawing app uses on a rotated phone for the same reason, and it puts Fold/Call/Raise
   under the right thumb rather than across the bottom edge where a landscape grip has
   the palm.

 /* ---------- Focus is brought to rest where it can be seen ----------
   The ring below was the easy half. The hard half is that the bar is fixed over the
   bottom of the page, so it is not in the flow and the browser does not know it is
   there: Tab to a control near the bottom and the browser scrolls it flush against the
   edge of the window — under the bar — and considers the job done. Measured by tabbing
   the whole page on a 390x844 phone: 16 stops came to rest completely covered and 27
   more partly. That is WCAG 2.2 SC 2.4.11, which asks that a focused control not be
   entirely hidden by something the page has put on top of it.
   scroll-padding is the fix, and it goes on the scroll container rather than on the
   controls: it tells the browser to treat the bottom of the viewport as not there when
   it scrolls something into view. The number comes from the bar, which already
   publishes its own height for the toast and the felt, so it cannot drift from the
   bar's real size the way a guess would — and it is already 0 when the bar is hidden or
   has become a rail down the side, which is the case scroll-padding-right answers.
   The toast publishes its height into the same sum, because when the browser does
   scroll it has to clear both.
   This is only half of it, though, and the half that is easy to mistake for all of it.
   scroll-padding only applies when the browser scrolls at all, and a control already
   inside the viewport is one it sees no reason to move — a fixed overlay on top of it
   does not enter into the decision. Measured on a 1280x900 desktop: tabbing to Common
   rulings while a toast was up left it completely covered, and this rule did nothing
   about it, because nothing scrolled. The other half is the focusin handler in main.js,
   which measures the overlap and scrolls by it. */

+runs over the table, the raise pad, all five overlays and Quick Split, at thirteen
 viewports from a
 360px phone to a 1600px desktop and the same phones on their side — each viewport
 twice, once with a mouse and once with a thumb, and at three table shapes, mid-hand:
 the sweep posts blinds, deals and calls three times before it measures anything, so
 the bets layer has chips on it. It used to audit a table nobody had ever bet at,
 which is a third of what is on the felt during a hand left unlooked at.
 The raise pad is newer than the rest and was worth every second it costs. It is part
 of the bar rather than an overlay, so nothing here had a step that opened it, and it is
 both the tallest thing the bar ever holds and the only place in the tool a dealer types
 an amount. The first sweep that opened it found a 36px-tall field on every phone in the
 list: the `hover: none` rule that sizes fields for a thumb names the settings panels and
 the seat form, and the one field on the one surface built for thumbs was not in the
 list. It also found the rail squeezing its own status line under the pad, which is the
 kind of thing that only happens in the state nobody was looking at.
 "Covered" and "out of view" are told apart before anything is hit-tested. An element
 clipped away by a panel that scrolls is not covered by whatever happens to be painted
 at that height, and reporting it that way is a diagnosis of something that isn't
 happening: the pot wizard's third winner, below the fold in a list, came back for four
 viewports running as "fully covered by button Confirm Winner(s)".
 Text is measured where it was painted, not where its box is. The two are different
 things and the difference is not academic: a name is centred, so its box is wider than
 its ink, and a name kept clear of the dealer's chip by a float is out of the way on the
 line beside the chip and full width on the line below. The check used to model that as
 "box minus padding", which is one way of keeping text out of somewhere and not the only
 one — it called every seat in the sweep an offender while the text sat exactly where it
 was meant to. Range rects ask the question directly, so padding, floats, centring,
 wrapping and a short label in a wide box all come out right without any of them being
 modelled.
 Offenders say how much is covered rather than that something is. "Is under a badge"
 reads the same for a stack a dealer cannot read and for a badge's rounded corner
 grazing the last digit, and the difference decides whether it is worth fixing. Probing
 the whole line and counting turned the residual this sweep has carried for three rounds
 into "1/7 under SB" — one probe of seven, on one configuration, in a thumb context
 only.
 More than one table shape is also newer than it sounds. The sweep ran on one — five

 ## What the sweep taught the layout
 For a long run of rounds the seat ring was *predicted* onto the table: work out the
 widest ring whose outermost puck still finishes inside the rail, place the seats, and
 trust it. The prediction is correct arithmetic and it was wrong on the page anyway,
 because every input to it moves after it is taken — the width search settles on a
 narrower puck, a name wraps to a second line or gets shortened out of one, the board
 appears in the middle. Each of those is up to 15px of puck height arriving after the
 answer. Ninety-six of the ninety-eight offenders this sweep could find were that.
 So render.js now finishes the way the audit judges it. After the seats are placed it
 measures where they actually landed, and if the worst of them hangs 6px past the rail
 the ring comes in by 6px and they are placed again — the same question this file asks,
 asked by the code that has to get it right. Two passes, bounded, because each one is a
 forced layout of the whole felt and it runs after every tap a dealer makes.
 That is the general shape of the lesson here: a layout that predicts itself has to be
 right about the future, and a layout that measures itself only has to be right about
 the present.
 That last part, and two of those checks, are newer than this paragraph claiming them.

 ## Which rule wins
 `feltShape.test.js` is here because of a change that measured as correct and was a
 no-op. The felt on a phone was made an upright oval by setting `--feltAspect` inside
 `@media (max-width: 700px)`, and forty lines below it `@media (max-width: 900px)` set
 the same property back to 1. Both queries match a phone, the declarations have the same
 specificity, and the later one wins — so the property was 1 on every phone on the site
 while the rule that was supposed to change it sat there reading perfectly.
 Nothing in the suite could have caught it and nothing in review did. A stylesheet is not
 a list of rules for viewports; it is a list of rules in an order, and the question "what
 does a 390px phone get?" has an answer that no single rule knows. So the test walks the
 media queries the way the cascade does — every declaration of a property on a selector,
 in source order, keeping the last one whose query matches — and asks what each of five
 real phone sizes actually ends up with. It carries just enough of a media-query engine
 for the forms this stylesheet uses, and refuses loudly rather than guessing when it
 meets one it doesn't know.
 The same file records a second thing, which is a floor that was added and removed. The
 `max-height` that keeps the felt above the action bar has no lower bound, so a tall
 enough bar presses the table flat; flooring it at the desktop oval looked obviously
 right. Measured, it was worse: twelve players all in with nine side pots takes the bar
 to 341px, which at 360x640 leaves 142px of room, and a felt floored to 242px keeps its
 shape by putting five of the twelve seats behind the bar. Unfloored it is flat and all
 twelve are visible. The slit the floor defended against turned out to be unreachable —
 it came from forcing the custom property by hand. A test now asserts the floor is
 *absent*, with the numbers, so it doesn't get re-added by someone reasoning the same way.
 ## A property the wording depends on
 `potBreakdown.test.js` covers how the pot breakdown says who can win each pot, and it
 leans on something `potCalculator.test.js` now proves: **pot eligibility is nested.** The
 main pot is everyone still live, and each side pot above it drops whoever was all-in
 below, so every side pot's players are a strict subset of the pot beneath it.
 That makes "who is in" and "who is out" complements, which is what lets the line name
 whichever of the two is shorter and never spell out more than half the table. Listing
 every eligible player instead meant the main pot's line was every name at the table and
 each side pot repeated it minus one — and the lines too long to fit were exactly the ones
 nobody needed, while the short ones at the bottom were the side pots a dealer actually
 announces by name.
 The nesting check runs 20,000 random tables, and it asserts on its own generator as well
 as on the code: if a change to the shapes stopped producing side pots, every assertion in
 the loop would be vacuous and the test would still pass, so it also requires that more
 than ten thousand of those tables had one.
 Writing that check is where a comparison against `Set.length` went in — a `Set` has
 `.size`, so `here.length < below.length` was `2 < undefined`, which is false. As an
 assertion it failed everything; as a filter in a throwaway script it had passed
 everything, which is how it survived long enough to be written down. Both readings are
 silent. Prefer asserting the count you expect over comparing two things whose shapes you
 have not checked.
 ## Testing a fault that broke nothing
 `sidebarPanels.test.js` reads `TexasHoldem.cshtml` rather than any JavaScript, because
 the fault it covers was not a bug. Every control worked and every id resolved. What was
 wrong was which panel a thing was in and what that panel was called.
 The sidebar was Table Setup, **Session**, Chip Legend, Keyboard and Table Notes, and
 Session held the standings, a waiting list, the hand log and the save/load/reset buttons
 — a topic, a task, a log and three utilities under one word. It measured 1206px and 103
 visible elements against 555 and 29 for the next biggest, and "The table itself" sat
 1052px down inside it, so reaching Reset table meant opening a panel called Session and
 scrolling past the money and the log to find it.
 Three things are asserted, and each of them is a claim a future edit could quietly undo:
 - **The names say what is inside them.** The list is checked literally, because the
  failure mode is a word like "Session" that could hold anything.
 - **Each name is a heading.** A `<summary>` is announced as a button, so the sidebar's
  names — its whole navigation — were not reachable by heading. Splitting Session also
  removed the four subheads that had been the only headings down there, so without a
  heading in each summary the page would have come out of this with a worse outline than
  it went in with.
 - **No panel goes back to being a grab-bag.** Not a size limit — Table Setup is
  legitimately long. It counts *subjects*: a panel that needs its own headings to list
  its parts is holding more than one thing. Two subheads survive, and the test names
  them, because Settle up is the standings at the end of the night and Stacks in chips
  is the chip legend counted out — the same subject at a different moment, which is what
  a subhead is for.
 The panels are split on the opening tag rather than parsed, which is sound only because a
 sidebar panel never contains another one; Table Setup's sub-panels carry a different
 class. That assumption is worth knowing about if one ever does.
 ## A warning is only worth having if its number is right
 `chipLegend.test.js` covers removing a chip colour, which was one click of an unlabelled
 24px button and was never a change to a legend. `computeContribution()` prices a seat by
 running the legend over that seat's chip counts, so a colour that leaves takes every chip
 counted in it off the table. Measured in a browser on a three-handed table: deleting the
 $500 row took **$22,500 of $26,874** with it, with no confirmation, nothing said
 afterwards, and no way back — a colour added again is a new colour with a new id, while
 the counts stay keyed to the one that left.
 Most of the file is about the number in the warning rather than the removal, because a
 warning that overstates is worse than none. The obvious way to work it out — chips times
 value — is wrong in **both** directions:
 - a seat with a typed amount is priced from that and its counts are never read, so a
  colour it holds is worth nothing to it;
 - a seat whose chips all leave falls through to the table's standing ante rather than to
  zero, so it loses less than its chips were worth.
 So the figure is the difference between pricing every seat with the colour and without
 it, and a randomised check across 2,000 tables asserts that what the warning claims is
 exactly what the table then does. That check found a third case nobody would have written
 by hand: fourteen $1 chips against a $200 ante, where removing the colour puts the table
 **up** $186. The wording says so in that direction too.
 The friction is conditional on purpose. A colour nobody has counted deletes on one click;
 only one that is holding money asks. A confirmation that fires every time is one nobody
 reads by the third night, and this is a tool where four other confirmations already
 compete for that attention.
 ## Every control says what it is
 `uiAudit.js` gained `controlNames()`, which is the general form of the bug above: the ×
 had no accessible name, so it was announced as a button and nothing else — five of them
 in a column, identical, each deleting a different colour.
 It treats a symbol as no name even though `×` is technically text. The rule is that a
 name has to contain a letter or a digit, which is the difference between "×" and "Undo".
 Names are resolved the way the accessibility tree does it — `aria-label`, then
 `aria-labelledby`, then a field's wrapping or pointing `<label>`, then placeholder, then
 text content, then an image's `alt`, then `title` — and anything under `aria-hidden` is
 skipped rather than judged, since it is not in the tree to begin with.
 Removing the one `aria-label` this round added makes it report all five buttons, which is
 how it was checked.
 ## Where the keyboard lands
 Two checks in `uiAudit.js` cover WCAG 2.2 SC 2.4.11, which says a focused control must
 not be completely hidden by something the page has put on top of it. Tabbing the whole
 page on a 390x844 phone found **16 stops resting completely covered and 27 more partly**,
 under the action bar; on the desktop, four more under a toast.
 They are checked as the fix rather than as the symptom, because the symptom needs a
 keyboard and this file has no automation of its own:
 - **`focusHasRoom()`** — `scroll-padding-bottom` on the scroll container has to reserve at
  least as much room as the fixed furniture standing at the bottom of the window. Only
  furniture crossing the middle of the screen counts, or the rail a landscape phone puts
  down the right-hand side would demand scroll padding the height of the whole window;
  and sticky elements inside a panel that scrolls on its own are excluded, because
  scroll-padding on the document would do nothing about them.
 - **`focusablesReachable()`** — nothing focusable may sit entirely outside the viewport
  inside a `position: fixed` subtree, since scrolling can never bring it back. The seat
  editor's bottom sheet was put away with `transform: translateY(105%)`, which moves a
  thing without putting it away: its Done button sat at y=850 on an 844px screen, still in
  the tab order and still on the accessibility tree. `visibility: hidden` puts it away.
 ### Half a fix looks exactly like a whole one
 `scroll-padding-bottom` alone was written up as the answer and it is only half of it. It
 applies when the browser has to scroll to reach the control at all; a control the browser
 already considers visible is one it will not scroll to, and a fixed overlay on top of it
 does not enter into that decision. Measured: tabbing to Common rulings with a toast up
 left it 100% covered, and `scrollIntoView({block: "nearest"})` moved nothing, because
 "nearest" was already satisfied. The sweep had shown clean only because 89 tab presses
 outlast an eight-second toast.
 So the other half is a `focusin` handler that measures the overlap and scrolls by it —
 and, when the page has no room left to scroll (26px available against 94px wanted, at
 1280x900), dismisses the toast instead. Sizing the page's bottom padding for the toast as
 well would have fixed it by making the page grow and shrink by 64px every time anything
 was announced, which is worse than the fault.
 ## A sweep only measures the states it reaches
 The action bar is fixed over the felt, so its height is the felt's budget — and the bar
 carries the side-pot breakdown, which drew one row per all-in with no ceiling. Measured
 on a 360x640 phone: five players idle put the bar at **151px**, six all-in at **303px**,
 and twelve all-in at **411px** — 64% of the screen, leaving **96px of felt** to draw
 twelve seats in.
 Nothing here could see it, and the reason is worth writing down. Every check in
 `uiAudit.js` asks whether some element is covered, clipped or unreachable; not one asked
 how much room the covering element had taken. But the deeper miss was the sweep itself:
 all 294 audits drove their table with `Call` and `Check`, so **no table in the history of
 this file ever had a player all-in**, and the one thing on the bar whose height depends
 on the table was empty in every single measurement. `runUiAudit.js` now has a fourth
 shape, twelve players shoved in for twelve different amounts — there is no one-tap shove,
 so it takes the raise pad's All-in preset and confirms, or `Call all-in` for anyone who
 cannot cover.
 - **`furnitureBudget()`** — the fixed bottom band, measured against the window. Failing
  above **50%**, which is the line that needs no taste to defend: furniture larger than
  the content it serves is a shape fault whatever it is showing. Warning above **30%**,
  the published guidance for persistent chrome, which the shortest phone does not meet at
  rest — the bar is 151px of a 640px screen before anything happens — and a sweep that is
  always red stops being read.
 ### Cutting the middle out of a list, and which end to keep
 The cap is four layers, and past it the bar draws the main pot, one line for everything
 between, and the newest side pot. The two ends are not an arbitrary choice: side pots are
 paid **from the newest one back down to the main pot**, so the top layer is the next thing
 that happens and the main pot is the last, and those are exactly the two a live dealer
 says out loud while the chips are being stacked — *"main pot 7,200, side pot 4,500"*. The
 layers between are the middle of that count-down, wanted at showdown, which is the pot
 wizard — the same builder, passing no cap, in a dialog that scrolls.
 `potBreakdownRoom.test.js` checks the parts that could go wrong quietly:
 - the row count is a function of the cap, not of the table — eight, nine, ten, eleven and
  twelve all-in all draw three lines
 - the drawn amounts still add up to every pot, so a dealer counting the announcement
  against the chips in the middle finds no shortfall the tool caused
 - the elision sits **where the gap is**, not appended after the list, so the amounts still
  read in the order the pots were made
 - it never fires when it would not buy anything: at exactly the cap the middle is one row,
  and swapping one row for one row loses an amount and gains a sentence
 Three injected faults — the cap ignored, the summary carrying only the first elided pot's
 money, the elision appended rather than kept in place — fail 6, 1 and 5 of the 11 tests
 respectively, and the audit check reports the original 64% when the cap is taken out.
 ## Two empty rows were setting how far apart twelve seats had to sit
 Every seat puck carries four rows: the name, the hole cards, the amount that player has
 put in, and their stack. Two of those are empty most of the time, and both held their
 space anyway.
 The amount pill was worse than empty space. It has a background, a pill radius and side
 padding, so with no text it painted an **8x11px green lozenge** — measured on **seven of
 nine seats** at an ordinary table. One of those is a component holding its place; nine is
 a rash, and a dealer has to learn to ignore a colour that on the other two seats means
 "this player has money out".
 The space was not free either. `seatRingRadii` sizes the ring from the tallest puck on
 it, so two rows nobody had filled were setting the spacing for the whole table:
 | | before | after |
 | --- | --- | --- |
 | iPhone 14, 9 seats | 78x88 puck | **78x63** |
 | iPhone 14, 12 seats | 44x65 | **66x55** |
 | Pro Max, 9 seats | 84x88 | **96x63** |
 | Galaxy S8, 12 seats | 8 overlapping pairs, 1556px² | 4 pairs, **87px²** |
 - **`emptyDecoration()`** — nothing inside `#pokerTableWrap` may paint a background or a
  border with no content in it. The rule is about paint, not space: an element may hold
  its place invisibly, and several do. With the old reservation restored it reports all
  seven pills; live it reports none.
 The one exemption, `.betChipDisc`, is on the list because the check reported it, not
 because it was predicted — it is a 13x13px circle filled with the denomination colour of
 the chip beside it, so the colour *is* the content. Three other exemptions were written
 from memory first and matched no element on the page at all, which is the argument for
 building that list from a run.
 ### The collapse is only safe because the cache key moved
 `resolveSeatLayout` measures ten candidate widths, each one a forced layout, and caches
 the result against `seatShapeSignature()`. That signature listed the names and the dealer
 seat — everything that could wrap a name onto a second line. It did not mention the two
 rows, because they always held their space and so could never change a puck's height.
 Once they collapse, they can. `seatPuckShape.test.js` checks the key moves when the first
 chips go in and when a hole card is entered, and — just as important — that it does *not*
 move for the second player to bet, or when an amount merely gets wider. It is a boolean
 over the whole table because that is what the measurement is: `measuredSeatBox` takes the
 tallest puck on the ring, so what matters is whether anybody has one. A per-seat key would
 be correct and would throw away the cache on every single tap.
 Measured on the running page: the ring settles by 24-26px when the blinds are posted —
 and it settled by **23-25px there before this round too**, because the action bar changes
 height at that moment and the felt is measured against it. The one place the ring moves
 is a place it already moved.
 ### A test that passed for the wrong reason
 The signature joins names on a control character so that "ann" + "abel" and "anna" + "bel"
 stay distinguishable. The first version of that test used `Ann`/`Abel` against
 `Anna`/`Bel` — which can never collide whatever the separator, because the capitals land
 in different places. It passed with the separator deleted and proved nothing. Lower case
 is what makes it a test. Four faults were injected in total; the other three (dropping the
 two flags, letting the count into the key instead of a boolean, and counting only hand
 bets so a table playing antes is missed) fail 3, 2 and 1 of the eight.
 ## Room the felt had and the type never got
 The felt grows with the window and the pucks did not — 96px was the only ceiling there
 was. Nine-handed, the seats covered 19% of the felt on a phone, 11% on a 1280px desktop
 and **8% at 1440px and beyond**, with the stack figure a dealer reads at **10px on a
 2560px monitor**, the same 10px as on a 360px phone.
 Two things stop the fix costing more than it buys, and `seatWidthSearch.test.js` checks
 both:
 - **Every candidate width is a forced layout.** Raising the ceiling for everybody took
  the layout pass from 24ms to 73ms twelve-handed on a desktop. A screen that cannot use
  the wider widths must not measure them, so a phone is checked to measure *exactly* the
  ten widths it measured before — same list, same order — and the measured cost on a
  phone is unchanged (10.7ms against 10.4ms, which is noise).
 - **A wide puck on a narrow felt is worse than a small one.** The first version let
  phones through, and a 144px puck on an iPhone's 278px ring is half the width of the
  table: six-handed, all six seats sat over the rail by 15px against 5px before, and it
  read as a stack of cards rather than a table with people around it.
 So the ceiling is a fifth of the felt's **shorter** span, capped at 144. Five is measured,
 not chosen: the shorter span is 233-303px on every phone in the sweep including sideways,
 and 617-714px on tablets and desktops, so any divisor between 3.2 and 6.4 separates them.
 The test pins both ends, so if the felt ever changes shape enough to bring those together
 it says so rather than letting the phones quietly start paying.
 Above the ordinary ceiling the puck also takes the larger type — `.seatsRoomy`, two steps
 up the scale for the two numbers read across the table and one for the chair number.
 Steps rather than a `clamp()`, for the same reason the tight set is: the width is a
 continuum and the type is a set of deliberate sizes.
 | nine-handed | before | after |
 | --- | --- | --- |
 | iPad puck / name | 96px / 12px | **134px / 15px** |
 | desktop 1440 puck / name | 96px / 12px | **140px / 15px** |
 | seats as a share of the felt, 1440 | 8% | **12%** |
 | every phone, every seat count | unchanged | unchanged |
 ### What the rail check is actually measuring, which is not the rail
 Found while checking the above and **not fixed** — written down here because the number is
 worth having and the fix is not a small one.
 `#pokerTable` is `border-radius: 50%`. Both the settle pass in `render.js` and
 `seatsOnTheTable()` in the audit compare a puck against the four edges of the table's
 **bounding box**, which is a different and much slacker question than the one the message
 "hangs Npx past the rail" claims to answer: at the top and bottom of the ring the oval
 curves away from its own box, so a puck can be comfortably inside the box and visibly
 outside the felt.
 Measured against the ellipse instead — a point is outside when `(dx/a)² + (dy/b)² > 1`,
 and the ray from the centre crosses the boundary at `1/√t` of the way out — across 35
 configurations the check is seeing **303px of overhang as zero**, including **46px on a
 phone held sideways** that has been there for as long as the check has.
 Settling against the ellipse was tried and reverted, because it is not the local fix it
 looks like. Pulling the ring in far enough to clear the oval crowds the seats, and on a
 twelve-handed phone with everybody all-in it put seat 3's centre inside seat 4 — the one
 trade the width search explicitly refuses to make, since a dealer can see a puck over the
 rail but cannot see a tap answering for the wrong player. Guarding against that instead
 leaves the ring out and the overhang worse: the sweep went from 6 failing configurations
 to 77, with 355 rail reports.
 Which is the finding. On a crowded table **keeping the seats off the rail and keeping them
 off each other are in genuine conflict**, and resolving it needs the two settled together
 rather than one bolted onto the other.
 ### And then measured again, and dropped
 Re-probed across 40 configurations — four table shapes at ten viewports — the gap is real
 and systematic: **31 of 40 sit further past the oval than the box says**, worst 34px
 against a box overhang of 0 everywhere. The 303px above was the all-in shape, which is the
 extreme rather than the case.
 Then it was looked at rather than measured, and 12–17px of a rounded puck's corner
 crossing the rail reads as players *at* a rail — which is what the thing is a picture of.
 The measurement gap is worth writing down and the appearance is not worth a round, so the
 lead is closed rather than carried forward. Worth the re-measure to find that out: the
 number that made it look urgent was the worst cell in the table, not a typical one.
 ## Eight rows that said only their own names
 The sidebar is eight `<details>`, and every one measured exactly 60px shut with nothing on
 it but its label — 480px of a phone's screen, and 480px of a 660px desktop column, spent
 saying "Standings", "Hands", "Waiting list". Whether the box balances, whether anyone is
 waiting for a seat, how many hands have been played: the page had **all three worked out
 already**, and charged a tap for each of them, on rows two thirds of which were empty.
 That is the disclosure pattern's named failure — a header you have to open to find out
 whether it was worth opening — and the answer the design systems give is the same one:
 put the status on the header. So each shut panel now carries the one fact you would have
 opened it for, and the panel keeps the sentence. "Off by $300" is the alarm; *which seat
 is holding chips nobody wrote down* is a paragraph, and that is the half that belongs
 behind the tap.
 Two rules hold it together, and `panelGlance.test.js` checks both.
 **A glance appears only when it has something a dealer would act on.** Eight rows that
 always say something are eight rows that say nothing again, and a row reading "Nobody
 waiting" all night is the clutter this went in to remove. So no waiting list, no notes and
 no hands yet are all silence, and the bank check stays quiet over a table nobody has
 bought into — which is what the panel does with its own check, for the same reason.
 **A glance never says something the panel under it would contradict.** It is read off the
 same state, never off the panel's DOM — a shut `<details>` has no rendered body to read —
 and one test walks three buy-in figures asserting the glance's colour agrees with
 `bankReconciliation`'s verdict and its number carries the same difference.
 The layout half is `glancesFitTheirRows` in the audit, and it took three goes.
 The first version asked only whether a row had grown taller than a row with nothing on it,
 which sounds like the whole question and is not: a glance floated back into flow and
 allowed to wrap **sailed straight through it**, because a float does not expand the box it
 sits in — two lines of note hung out of a row that still measured exactly 44px. Asking
 where the glance actually ended up, in both axes, is the question that has an answer.
 The second version was wrong in the other direction, and **the sweep caught it on its
 first clean run**: 94 failing configurations, 91 of the offenders this check's own. It
 takes the shortest row in the sidebar as its idea of a bare one, and the Keyboard panel is
 `display: none` under `pointer: coarse` — a touch device has no keys to press — so on
 every viewport visited with a thumb the bar was a row that wasn't drawn at all, 0px, and
 all seven real rows read as grown. Seven rows times thirteen viewports is exactly the 91.
 Rows that aren't rendered aren't rows.
 Which is the point of running the sweep against a check as well as against the page. A
 narrowing fix has to be shown not to have blinded the thing it quietened, so the four
 broken versions are re-run **with the Keyboard panel hidden** — the condition that was
 breaking it — and each is still caught, while the unbroken page stays clean.
