Make every seat on the ring the same seat, and measure it before believing it

Nine chairs, and until this no two of them were the same size. Measured at 1280x900
with five 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.

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 the thumb of someone trying to tap it
— and because the ring is sized against the tallest puck on it, the whole table could
resize with it.

Three rows are held open instead: the name, the amount, and the stack. The name gets
one line whatever it says, the amount pill keeps its row when it is empty rather than
collapsing, and each row is a token rather than an em so an amount stepping its type
down to fit shortens its digits and not its row. What the puck says changes all night;
how big it is does not.

It costs nothing. measuredSeatBox already took the tallest puck on the ring, on
purpose, so the room was reserved at every seat and the short ones simply weren't
drawn into it. What pays for the third row is the second line of name going away: an
earlier round measured uniform-with-two-lines at 88px and rightly refused it.
Uniform-with-one is 71.

  A name with no word to drop steps its type down instead of ellipsising. fitSeatNames
  turns "Mike from work" into "Mike", which is what the table calls him, and could do
  nothing at all with "Christopher" — so that one was cut to "Christo…" on a felt that
  may also have a Christine at it. The amounts on the same puck have never taken that
  trade; this is fitAmount's rule applied to the other thing a dealer reads across a
  table. One step, floored at 9px, then the ellipsis.

  The float that kept the button seat's name off the dealer chip goes with the second
  line — three rules of it, indenting the first line so a long name could drop below
  the chip onto a second. There is no second line to drop to, and left in place it drew
  "Christopher" as an empty label. The padding every crowded ring already used is the
  rule at all sizes now, widened from 22px to 25 so it actually covers the chip and the
  gap it is inset by.

Then the part that was quietly wrong. renderSeats builds nine empty pucks and fills
them afterwards, so the layout search ran against blank boxes and cached the answer
under a key naming a table it had never measured. On a 390px phone that is a ring
sized for empty seats — and the comment where it was cached said "let the resize that
follows do this properly". Nothing resizes a phone. Turning the phone sideways and
back was the only thing that ever fixed it, and it fixed it into a different layout:
same viewport, same table, 90px pucks on load and 72px after a rotate.

So the finished pucks are measured against the box the search settled on, and if they
disagree the search is asked again with the real thing in front of it. Once, and the
second answer is cached. Fresh load and rotate-and-back now agree exactly.

That also lets the cache key shrink to almost nothing. It used to name every player's
name, the dealer's seat, whether anybody had cards and whether anybody had chips out —
four things, three of which flip during an ordinary hand, each flip a ten-candidate
re-search. None of them can change a puck's height any more. Measured over three calls
in a row: no re-search, and not one of the nine seats moved a pixel.

The crowded ring gives up the 1.4 leading on its money rows to pay for the row it now
holds open — 10px of figures is 12px of ink and the rest was blank. Without it the
Galaxy S8 twelve-handed, where the pucks are already at the 44px floor, put
neighbouring seats' blind badges down onto each other's "ALL IN". Hanging the badges
further out was tried first and is the wrong direction: the badge landing on a stack
figure belongs to the seat next door, so every pixel further out is a pixel further
onto a neighbour.

992 unit tests. 320 layout audits across 13 viewports with a mouse and a thumb: one
failure, the chip behind seat 11 that master already carries.
