+
+                   This panel is the one thing that is open when the tool is first
+                   opened, and it was 886px of a 667px phone — the two figures its own
+                   summary glances at, the blinds, sat below 218px of prose explaining
+                   three switches a dealer may never touch. The three have gone into
+                   "While you deal" below, with the paragraphs that explain them, which
+                   is where House take and Without live betting already were: the panel
+                   had the vocabulary for this and was only using it for money. *@
+                @* Every field below takes digits and none of them is type="number".
+                   That is deliberate, and it is the second half of a fix — the first
+                   half is Render.setField, which stopped a re-render writing over the
+                   text somebody was still typing.
+
+                   type="number" was costing more than it paid here. It silently drops
+                   characters it dislikes with no feedback to the person or to assistive
+                   tech; it reports a half-typed "0." as "0", which is what let the
+                   decimal point be written away; it does not expose selectionStart, so
+                   nothing can put a caret back where it was; it draws a spin button
+                   into a 54px-wide blind field, where five digits already need 45 of
+                   the 52 available; and it is the control GOV.UK dropped from their
+                   number patterns after user testing, for the same reasons plus Dragon
+                   and NVDA.
+
+                   inputmode is what actually summons the keypad on a phone, and it is
+                   the better keypad: "decimal" carries the separator for the reader's
+                   locale, which is the key a dealer needs to type 0.25 and the one
+                   type="number" leaves them hunting for on iOS.
+
+                   min/max/step go with it. Nothing relied on them: the seat count is
+                   clamped to 2..24 in main.js before it is used, and the money fields
+                   are read through a finite-number check that a spinner never provided
+                   anyway. *@

+        @* One question with three answers, not two boxes with four corners.
+
+           A seat is sitting out, in the hand, or folded — and "folded" only means
+           anything while the seat is in. So the two checkboxes here could be ticked
+           into a state that means nothing, and the code that stopped them doing it
+           `disabled` the Fold box whenever In hand was clear. Measured: that left the
+           label at the same opacity and the same colour with a `title` on it, so a
+           dealer pressing Fold on a seat that was sitting out got no movement and no
+           reason — the exact thing round 16 went through the tool to remove, hiding
+           from the rule that finds it because the title sat on the label rather than
+           on the control.
+
+           Three named states cannot contradict each other and none of them is ever
+           unavailable, so there is nothing left to dim. The radiogroup is the same
+           shape the card picker's suits use. *@

+                        The most common argument at a home table. A player facing a bet who
+                        pushes out a single oversized chip without saying anything has
+                        <em>called</em> — not raised, however big the chip is. To raise with one
+                        chip you have to say "raise" before it lands; say it without an amount
+                        and the raise is the most that chip allows.
+                    </p>
+                    <p>
+                        Facing no bet, the same silent chip is a bet of the whole chip. And a
+                        clear verbal declaration in turn is binding either way — if words and
+                        chips disagree, whichever came first is the action.

+   players seated, 64px for Bob, 70 for Christopher because his name wrapped, 71 for
+   Alexandra because she had chips out, 89 for "Mike from work" who had both. Twenty-five
+   pixels of difference around one ring, and the ragged edge was the smaller half of it.
+
+   The larger half is that the sizes *moved*. A puck grew 17px the moment its player put
+   money in and shrank again when the street closed, so the felt reflowed twice a hand
+   under a dealer's thumb — and the ring is sized against the tallest puck on it, which
+   meant every one of those changes could resize the whole table.
+
+   Three rows are held open instead: the name, the amount, and the stack. Each is a token
+   rather than an em, so an amount that steps its type down to fit (see .puckAmountLong)
+   shortens its digits and not its row. What the puck says changes all night; how big it
+   is does not.
+
+   Sized so it costs nothing. The ring already reserved room for the tallest puck at every
+   seat — measuredSeatBox() takes the maximum, on purpose — so drawing the short ones at
+   that height spends room that was already spent. What pays for the third row is the
+   second line of name going away above: uniform-with-two-lines was 88px, which an earlier
+   round measured and rightly refused. Uniform-with-one is 71. */

+   them rather than separate sizes to be kept in agreement — and capped, which is the one
+   place in this stylesheet where type does not follow the browser's font size.
+
+   Why it has to be. Every row above is a `px` token so that an amount stepping its type
+   down shortens its digits and not its row — but a token is a floor, not a ceiling, and
+   text bigger than its row simply makes the row taller. Turn a phone's text up to the
+   125% its slider offers and --fs-2xs goes from 10px to 12.5, the two money rows go from
+   14px each to 17.5, and the puck grows with them. At 150% the figures were being cut
+   off by the puck's own edge; on the tightest ring, where twelve pucks are already at
+   the 44px a thumb needs and there is nowhere narrower to go, they came down on each
+   other instead — the sweep measured seat 3's "$1,495" five-sevenths under seat 4's BB
+   badge at every phone in the list.
+
+   `min(…, Npx)` is exactly the size each of these has always been drawn at, so nothing
+   changes for anybody at an ordinary text size: the cap only ever engages where the
+   alternative is a figure clipped in half or two seats printed on top of each other.
+   And what it holds is the one thing on the page that is also somewhere that does
+   scale — the Standings panel lists every stack in full, at whatever size its owner
+   asked for. The felt is a diagram; its cells are sized by the table, and their writing

-   A float is what indents only the lines it sits beside, which is the whole of the

-   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.

+
+   There are four things a puck can say about where a seat sits in the hand: small blind,
+   big blind, straddle, button. Three of them were pills hanging off the top-left edge and
+   the fourth was a 22px disc inside the top-right corner, in the middle of the writing.
+   So the dealer's eye had two places to look for one class of fact, and the corner one
+   was charging the name a quarter of its width to be there — see .seatPuckName above for
+   what that cost in names.
+
+   It hangs off the edge exactly as far as the badges do and no further, because that
+   distance is not free: render.js's SEAT_BADGE_OVERHANG_PX charges every chair on the
+   ring for it, once, and seatFootprint.test.js holds the three numbers together. Same
+   5px, so the ring does not move at all — this chip now fits in room the felt had already
+   reserved for the badge on the other corner.
+
+   Which is what sets its size. 12px, the badges' height, is what fits between -5px and
+   the top of the name: on the tight ring the name starts 8px down (1px border, 3px
+   padding, 4px of margin), and the chip reaches 7.

+

+
+   The block above moved the action bar off the bottom edge because a landscape phone is
+   short of height and swimming in width. The sheets never got the same news. Measured
+   on the fullest menu the tool can build, twelve-handed with somebody waiting:
+
+     640x360   545px of content in a 306px sheet — Cash out…, Move to…, Edit seat…,
+               Small blind, Big blind and Cancel below the fold, Cancel by 224px
+     667x375   545 in 319, Cancel 211px under
+     844x390   529 in 332, Cancel 183px under
+
+   and in all three the sheet was 420px wide in a window 640 to 844 wide. Two hundred
+   and forty-seven pixels of width held empty, on the one screen shape whose whole
+   problem is height. A dealer holding the phone sideways had to scroll a menu to find
+   the way out of it.
+
+   The sheet takes the width instead. The two tiers this menu has been sorted into since
+   round 7 — what you press with cards in the air, and housekeeping between hands — stop
+   being the top and bottom of a column and become the right and left of a row. Which
+   half goes right is not arbitrary: Fold and All-in sit under the same thumb the rail
+   above put Fold, Call and Raise under, so the urgent half of the screen is in the same
+   place whether the dealer is looking at the bar or at a seat.
+
+   Cancel goes under them, in the same column, because the way out belongs at the thumb
+   too — and because a full-width Cancel under both columns is 60px of the 306 there
+   are.

+## The sweep had never once been run at a size anybody sets
+
+Every length in `holdem.css` that isn't a structural clearance is in `rem`. That is the
+right way round: it means the whole page follows the browser's font size, which is what
+a phone's text-size slider changes. It also means the page had a whole axis of behaviour
+that 320 audits had never touched, because every one of them ran at the default 16px.
+
+A third pass now runs the same surfaces on the eight phone-shaped viewports with the
+root at **20px** — the 125% an Android accessibility slider gives you. It found four
+things on its first run, and every check that caught them was already written:
+
+- **The page slid sideways.** `#holdemHeaderActions` was `flex-wrap: nowrap` with three
+  `white-space: nowrap` labels inside it, so when they stopped fitting they had nowhere
+  to go: "Resolve Pot" ended 23px past the right edge of a 360px window and put a
+  horizontal scrollbar under the whole document. At 24px it was 60px past the edge of a
+  390px one. `page never scrolls sideways` had been in the audit for months and had never
+  had anything to say.
+- **Figures painted over the seat next door.** Which of the two type steps an amount got
+  was decided by *counting characters* — eight for one, ten for the other — which is a
+  guess at how wide a figure is that happens to hold at one text size and one puck width.
+  At 20px, "$1,200" is six characters, took no step at all, and wanted 38px of a 34px
+  puck. `Render.fitAmounts` measures now, in the same batched passes `fitSeatNames` uses,
+  and takes the separators out before it takes a step of type.
+- **Pucks grew and the ring could not answer.** The row heights are `px` tokens so that
+  an amount stepping its type down shortens its digits and not its row — but a token is
+  a floor, not a ceiling, and text bigger than its row makes the row taller. The puck
+  went from 55px to 65 and twelve of them came down on each other, because at the 44px
+  floor there is nowhere narrower for the search to go. The two sizes a puck is written
+  at are capped at exactly the sizes they have always been drawn at, so nothing changes
+  at an ordinary text size; the felt is a diagram, and the rule that already governed a
+  puck's width now governs its height. `.seatsRoomy` is exempt — those pucks have room.
+- **A check that was crying wolf.** `no control is parked where scrolling can't reach it`
+  flagged the raise pad's Cancel and Raise-to in the landscape rail. The rail is
+  `overflow-y: auto` on purpose and they were one flick away, so the message was untrue;
+  it now asks whether a scrollable ancestor can bring the control back. What was true is
+  that the rail opened at its *top*, so the overflow came off the bottom — where the two
+  buttons that end a raise are. It opens at the end now, which is the same reason it is
+  anchored low in the first place.
+
+One shape it is not held to, with the arithmetic in `runUiAudit.js`: twelve players
+all-in on a 360x640 phone. The action bar is at its tallest there — 283px of the 640 at
+20px — and with the header that leaves the felt 290x163 where it had 296x262. Twelve
+pucks 44px wide (the floor a thumb needs) and 62px tall do not fit around an ellipse
+163px deep. That is a geometry with no answer rather than a fault with a fix, so it is
+reported as a note every run instead of a failure every run — a sweep that is always red
+stops being read.

+    // 360px phone and took the document's scroll width with it. Every check in the
+    // audit already knew how to catch that; not one of them had ever been run at a size
+    // anybody actually sets.
+    //
+    // One shape it is not held to, and the arithmetic for why. Twelve players all-in on
+    // a 360x640 phone is the tallest the action bar ever gets — the status block and the
+    // pot breakdown both grow with the text — and at 20px it stands 283px of the 640,
+    // which with the header leaves the felt 290x163 where it had 296x262. Twelve pucks
+    // 44px wide (the floor a thumb needs; there is nothing narrower to go to) and 62px
+    // tall do not fit around an ellipse 163px deep: two per side is all the height there
+    // is, and the sweep reports it as seats 9, 10 and 11 written across each other.
+    //
+    // That is a geometry with no answer rather than a fault with a fix, so it is
+    // reported as a note every run instead of a failure every run. A sweep that is
+    // always red stops being read — the same reasoning as the 30% furniture warning.
+    //
+    // The packed table is the same arithmetic and was only ever passing by luck.
+    // Measured on the same 360x640 phone at 20px, with nobody all-in: the felt is
+    // 330x294, the pucks are 44x63, and five of them sit down each side — 315px of puck
+    // into 294px of felt, with the pitch between neighbours at 35px and 51px against a
+    // puck 63px tall. They overlap by construction, worst case 12px, and they always
+    // have. What kept the sweep green was the hit-test probes landing in the gaps
+    // between the glyphs; a change anywhere that moves the ring by three pixels moves
+    // the probes onto the overlap and the run goes red for something nothing in the
+    // change touched. Twice this round, from a stylesheet reset and from a sidebar
+    // panel getting shorter.

 // What the ring is allowed to be sized from.
 //
-// Two rows in every seat puck are usually empty — the hole-card line, and the pill that
-// shows what a player has put in. Both used to hold their space anyway, and the pill,
-// which has a background and a pill radius and side padding, painted an 8x11px green
-// lozenge when it had nothing to say: measured on seven of nine seats at an ordinary
-// table, a coloured mark on almost every seat standing for nothing.
+// resolveSeatLayout buys its answer with ten forced layouts — ten candidate widths, each
+// applied to the felt and read back — and caches it against this signature. So the
+// signature has to move whenever a puck's height can, and must not move otherwise: one
+// that changed on every action would throw the cache away on every tap, which is the
+// whole cost it exists to avoid.
 //
-// The space was not free either. seatRingRadii sizes the ring from the tallest puck on
-// it, so two rows nobody had filled were setting how far apart the seats had to sit. On
-// an iPhone 14 nine-handed the puck measured 78x88 with 25px of that reserved for
-// nothing; collapsed, the width search settles on 78x63. Twelve-handed on a Galaxy S8
-// the seats overlapped by 1556px² and now overlap by 87px².
+// It used to name four things: every player's name, the dealer's seat, whether anybody
+// had hole cards, and whether anybody had chips out. Three of those flip during an
+// ordinary hand. A dealer calling a bet paid ten forced layouts for it, and so did the
+// next street closing, and so did editing a name.
 //
-// The collapse is only safe if the layout re-measures when one of those rows fills,
-// because resolveSeatLayout caches its ten forced layouts against this signature. That
-// is what is checked here: the cache key has to move when the puck's shape can, and
-// stay still when it cannot — a signature that changed on every action would throw the
-// cache away on every tap, which is the cost it exists to avoid.
+// None of them can change a puck's height any more. The stylesheet holds three rows open
+// — name, amount, stack — at a height that does not depend on what is written in them:
+// the name gets one line whatever it says, the amount pill keeps its row when it is
+// empty, and the dealer's chip changes a padding rather than a line count. What is left
+// is the hole-card row, which still collapses, because whether a table tracks hole cards
+// is something it decides once rather than something that changes under a thumb.
+//
+// The other half of that bargain is in renderSeats: it measures the finished pucks
+// against the box the search settled on and asks again if they disagree. That is what
+// makes a wrong assumption here a stale frame rather than a stale session — and it is
+// what catches the first render of all, where the pucks are built empty and the search
+// that used to run against them was measuring nine blank boxes.

+// Two faults, one on top of the other, and the sweep could see neither.
+//
+// #seatsLayer is a transparent `inset: 0` sibling of the table that holds the seat
+// pucks. The pucks ring the felt; the middle of it is empty layer — and an element with
+// no background still hit-tests. So every tap aimed at the community cards landed on the
+// layer instead. Measured at 1280x900 with the board on and five cards out: all five
+// hit-tested to `div#seatsLayer`, on every screen wide enough to keep the board in the
+// middle rather than on the strip. Each one is a button that opens the picker for that
+// card, and not one of them could be pressed. #betsLayer, the other sheet over the felt,
+// has been `pointer-events: none` since it was written.
+//
+// Underneath that, the cards were a little over half the size they were meant to be.
+// `placeBoard` measures how much middle the felt has and writes it to the centre's
+// `max-width` — but a max-width caps a box, it does not claim anything, and the centre
+// is a flex column that sizes to its content. So with 463px of measured room it went on
+// being 136px wide, the board row inside it is `width: 100%` of that, and five cards
+// sharing 136px come to rest on their own `min-width`: 24px, against a 44px floor this
+// sweep holds every other control on the felt to. On the strip, where the row simply
+// gets the width of the page, the same cards have always drawn 44.
+//
+// Neither was visible to a scripted probe — `.click()` on a node skips hit-testing
+// entirely — and the sweep's occlusion check had only ever been shown three selectors'
+// worth of the page: the action bar, the header, and the seats.

+// The one control in the header that is named for a hand and never starts one.
+//
+// "Next hand" names three different actions in this tool. The action bar's green button
+// deals one. The pot wizard finishes on "Start Next Hand" and hands back a table ready
+// to deal. And the header shortcut — which, between hands, deals nothing: it moves the
+// button on a second time, so the seat that was about to pay the big blind is skipped
+// and the next one pays it instead.
+//
+// Measured before this changed: settle a pot through the wizard, and the table is on
+// hand 6 with the button on seat 2 and the bar offering "Post blinds & deal". Press the
+// header's "Next Hand ⟳" — no confirmation, because there is nothing in the middle to
+// warn about — and the table is still on hand 6, with the button on seat 3. The toast
+// then opened with the same two words the wizard's button had just used, which reads as
+// a confirmation of the thing that was already done rather than a report of a second
+// rotation.
+//
+// The mechanism is right and stays: a dealer does pass the button along on a hand nobody
+// played, and state.startNextHand says so in as many words. What was wrong was the name.
+// A command is named for the state the system moves into — NN/g's Button States, "Show
+// Tab Bar" against "Hide Tab Bar" — and between hands the state this moves into is a
+// moved button, not a new hand.
+//
+// So the label is read off the hand: "Next Hand ⟳" while one is out, "Move Button ⟳"
+// when none is. Both claims are checked here, along with the trap underneath them — the
+// title is cached once from the markup for the dimmed-reason machinery to borrow and

+// write-back erased the point, and assigning `.value` to a number input parks the caret
+// at position 0, so every digit after it landed at the front.

+// Fifty-two cards on a phone.
+//
+// The picker put the whole deck on the screen at once — four suits across, thirteen
+// ranks down — and that grid is 646px tall. Measured with the board tracked and seven
+// cards already out:
+//
+//   640x360   816px of content in a 317px sheet, 40 of the 52 below the fold
+//   667x375   816 in 330, 40 below
+//   844x390   774 in 343, 36 below
+//   375x667   816 in 587, 20 below
+//   1280x900  774 in 775, none
+//
+// So on every phone the tool is actually used on, entering the flop began with a
+// scroll, and a dealer looking for the nine of diamonds read down a column to find it.
+// There is no arrangement that fixes that: fifty-two targets at the 44px this sweep
+// holds everything else to need 572px of width before gaps if they are thirteen across,
+// which is wider than any phone in portrait, and thirteen rows deep if they are four.
+//
+// A card is not one choice out of fifty-two. It is two — a suit and a rank — and that
+// is how a dealer says it out loud. So the sheet asks them in that order: four suits on
+// a row, then the thirteen ranks of the one chosen. Seventeen targets instead of
+// fifty-two, none of them smaller than they were, and measured afterwards at eight
+// viewports from 360x640 to 1280x900: nothing below the fold, nothing scrolling, every
+// button still at least 44x44 and still hit-testing as itself.
+//
+// The second tap is not a second cost in the usual case. The suit stays where it was
+// put, so a second card of the same suit is one tap — and picking one card used to be
+// one tap plus a scroll through thirteen rows.

+// Modal exists because six overlays were each missing the same three things, and it
+// fixed all six at once by answering one question the same way everywhere: focus the
+// first control, and hold Tab between the first and the last. Measured this round, that
+// single answer had gone wrong in three separate directions.
+//
+// It could not see a <summary>. The rulings sheet is twelve of them and one Done

+// back to it: eighty Tab presses, one element ever reached, twelve rulings that could
+// not be opened without a mouse.
+//
+// "The first control" was the card picker's Clear. The sheet a dealer opens to write a
+// card down opened on the button that rubs one out — the one thing the APG says to keep
+// a dialog off. And "the first control" is not an answer six dialogs share: Roselli's
+// rule is that a dialog long enough to scroll should land on its heading so the reader
+// can orient, and a short question with one irreversible answer should land on the
+// answer that leaves them no worse off.
+//
+// And a sheet that redraws itself was deleting the control that held focus. Choosing a
+// buy-in, picking a card, switching slots, confirming a side pot: all four left focus on
+// the document body, which inside a modal is nowhere at all.

+// What a seat is doing, asked once.
+//
+// The seat editor had two checkboxes, "In hand" and "Fold". A seat is really in one of
+// three states — sitting out, in the hand, folded — and "folded" means nothing while
+// the seat is out, so two boxes offered a fourth corner that has no meaning. The code
+// that stopped a dealer reaching it `disabled` the Fold box whenever In hand was clear.
+//
+// Measured: that left the label at opacity 1 and colour rgb(170,170,170) — identical to
+// a live one — with a `title` of "Folded" on it. So pressing Fold on a seat that was
+// sitting out gave no movement and no reason, which is the exact failure round 16 went
+// through the whole tool to remove. It hid from the sweep rule that finds those because
+// the title sat on the <label> rather than on the control the rule inspects.
+//
+// Three named states cannot contradict each other and none of them is ever unavailable,
+// so there is nothing left to dim.
+//
+// The second half of this round is where that form appears at all. The phone block's
+// own comment has always said why the editor becomes a bottom sheet — "the seat editor
+// lives far enough down the page that tapping a seat looks like it did nothing" — but
+// the sheet was scoped to 700px while #holdemLayout goes to one column at 900. The two
+// tiers in between had precisely the fault the sheet was written to fix. Measured,
+// tapping a seat:
+//
+//   844x390   the editor drew in the flow at y=369 in a 390px window: 21px of 401 on
+//             screen, 5% of it, at scrollY 0 with nothing scrolling it into view.
+//   768x1024  31% visible, the rest below the fold, and again no scroll.
+//
+// Afterwards every viewport from 360x640 to 900x500 shows 97-99% of the sheet, and
+// above 900 the editor is a static block at the top of a sidebar that is beside the
+// table rather than below it — 100% visible there too.

+// The seat menu on a phone held sideways.
+//
+// The tool learned two rounds ago that a landscape phone is short of height and
+// swimming in width: the action bar stops being a bar across the bottom and becomes a
+// rail down the right. The sheets were never told. Measured on the fullest menu the
+// tool can build — twelve seated, somebody on the waiting list, blinds still the only
+// money in:
+//
+//   640x360   545px of content in a 306px sheet. Cash out…, Move to…, Edit seat…,
+//             Small blind, Big blind and Cancel all below the fold, Cancel by 224px.
+//   667x375   545 in 319, Cancel 211px under.
+//   844x390   529 in 332, Cancel 183px under.
+//
+// And on all three the sheet was 420px wide inside a window 640 to 844 wide. Two
+// hundred and forty-seven pixels of width held empty on the one screen shape whose
+// whole problem is height, while the dealer scrolled a menu to find the way out of it.
+//
+// The two tiers this menu has been sorted into since round 7 — what you press with
+// cards in the air, and housekeeping between hands — stop being the top and bottom of
+// a column and become the right and left of a row. Fold and All-in land under the same
+// thumb the rail puts Fold, Call and Raise under, with Cancel beneath them. Measured
+// after: 297px in a 298px sheet at 640x360 and at 667x375, 281 in 282 at 844x390.
+// Nothing below the fold on any of them, and the move picker's twelve chairs and its

+// A control that can't act, pressed on the device this tool is for.

+// Measured on an iPhone, three hands dealt, the card picker open on an empty seat:
+// seven of the fifty-two cards were greyed out, none of them could take focus, and
+// tapping one changed nothing whatsoever — no toast, no text, not a byte of DOM. The
+// tool did have an answer to "who has the ace of spades?"; it was a `title`, and a
+// `title` needs a mouse. The same held in the header, where a new dealer's very first
+// screen is two dimmed buttons, and on Export CSV, which was greyed out with no
+// explanation written anywhere at all.
+//
+// `disabled` is the wrong attribute whenever there is something to say. It takes the
+// control out of the tab order, so a screen reader never lands on it and never hears
+// the description; and it eats the press on a touch screen, where the hover that would
+// have shown the `title` does not exist. NN/g's rule for the case is explicit — on a
+// touch interface, a press on a disabled control should raise the explanation — and
+// WCAG 3.3.1 wants the instruction reachable at all. `aria-disabled` announces the same
+// state and leaves the control reachable, so the press arrives and is answered.
+//
+// It also fixed something nobody had noticed. The picker's arrow keys hunted past dealt
+// cards, because a `disabled` button cannot hold focus — and hunting did the exact thing
+// the grid's no-wrap rule was written to prevent: Right from the ace of spades over a
+// dealt ace of hearts landed on the ace of diamonds, so the column silently shifted and
+// the next press of Down walked a different suit. A cell that can hold focus needs no

+// Undo, and whether a dealer can actually get to it.
+//
+// This tool prefers undo to confirmation — NN/g's own preference, and `runUndoable`
+// says so in as many words: "it now just happens, and the toast offers the way back for
+// the few seconds anyone would notice a misclick." That makes the toast's Undo the
+// safety net under the biggest things the tool does. Three ways it wasn't one:
+//
+//   * Every whole-step undo clears the per-action history on its way past, so the bar
+//     has no pill left and this button is the only way back. Measured on a desktop it
+//     is the 67th of the page's 68 tab stops, and it is gone in eight seconds. `U` —
+//     the key the sidebar legend advertises as taking back the last action — found
+//     nothing at all and did nothing.
+//   * The eight seconds ran whatever the dealer was doing. A cursor resting on the
+//     toast did not stop it; nor did tabbing onto the button itself. Measured: focus
+//     the Undo, wait 8.6 seconds, and the toast is gone and focus has been handed to
+//     <body> — the offer withdrawn and the dealer's place in the page with it.
+//   * Each toast carried its own role="status" inside #toastHost, which is already a
+//     live region in the markup. A region nested in a region, announced twice.
+//
+// The timing rules here are the usual ones: three to four seconds for a plain
+// confirmation, six to ten for anything carrying a button, pause on hover and on
+// keyboard focus, and always a manual way out — which is what WCAG 2.2.1 asks of
+// content that disappears on a clock.

+// One number, one control, and a ceiling that matches the table.
+//
+// "Split between" on Quick Split was two controls for one value sitting on top of each
+// other: a row of chips 2 3 4 5, and under it a bar reading "2 ways" with a − and a +.
+// Measured on an iPhone: 134px with its label, against 74px for "Smallest chip in play"
+// right below it, which offers five choices in one row. And the number was written down
+// three times at once — chip "2" lit gold, "2 ways" in the bar, and "Each of 2 players
+// gets" in the result panel above. Two of those three were controls.
+//
+// The bar was never meant to be a bar. `.waysStepper` asked for `min-width: 150px` in a
+// wrapping flex row, so on any phone it wrapped to a line of its own, and `flex: 1 1
+// auto` then gave it all 358px of that line: 252px of empty readout with the − and the
+// + pushed 304px apart. One-handed, on a screen 390px wide, they cannot both be reached.
+//
+// So the chips get a fifth chip. It reads "6+" whatever is behind it, because behind it
+// is where the count is written, and the stepper only exists once you are through the
+// door. Under six ways — every chop a home game will ever run — the field is one row.
+//
+// Two more things went with it. Neither stepper on this screen ever disabled an end, so
+// − at the floor and + at the ceiling looked live and swallowed the tap; NN/G's stepper
+// guidelines ask for exactly the opposite. And the per-pot chop capped its + with
+// `Math.max(contenderCount, MAX_WAYS)`, which is always 12: a side pot that only P1 and
+// P2 were eligible for would happily be chopped ten ways at $12 each.

+// The pill that names what Undo would take back, and whether it manages to.
+//
+// The bar's undo is a standing control rather than a toast per action, and it is a fixed
+// width on purpose: its text changes on every tap, and a control that resizes under a
+// thumb reads as the interface twitching. Measured on a phone that leaves the label
+// 78px, which is not enough for any label with an actor on it — so the label is three
+// elements (arrow, actor, act) and `ActionBar.fitUndoLabel` drops the actor whole rather
+// than letting an ellipsis land wherever it lands.
+//
+// That machinery was right and the labels being fed to it were not. Two rules follow
+// from "the actor is the half that goes", and six of the fifteen labels broke one:
+//
+//   The act has to name the action on its own. Four labels put a *verb* in the actor's
+//   slot — "dealing" + "the hand", "dealing" + "everybody in", "calling" + "the straddle
+//   off" — so dropping the lead left the pill reading "↶ the hand", which is what it
+//   said after every deal of the night, and "↶ the straddle off". Neither names an
+//   action.
+//
+//   The act has to fit, because whatever is left is ellipsised. Measured at 390x844 and
+//   360x640 with a thumb: "hand killed on the clock" wanted 125px of 78, "check on the
+//   clock" 99, "waiting for the blind" 103, "posting to come in" 97. All four came out
+//   cut mid-phrase — "↶ waiting for th…".
+//
+// Both are fixed by writing the labels differently rather than by changing the fitting:
+// the qualifier moves into `long`, which is the whole sentence, and the verb stays on
+// the pill. Every short form is a substring of its long form, which is what Label in
+// Name asks of a control that has shortened its own name — and it is what lets `long`
+// be the accessible name rather than only a `title` nothing on a phone can reach.
+//
+// Measured after, on both phone sizes: nothing ellipsised, and every visible form
+// contained in the name. The one exception is stated below.
