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 — and the stack figure a
dealer reads sat at 10px on a 2560px monitor, the same 10px as on a 360px
phone, well under every published floor for text meant to be read.
Two things stop this costing more than it buys.
Every candidate width is a forced layout. Simply raising the ceiling took the
layout pass from 24ms to 73ms twelve-handed on a desktop, so a screen that
cannot use the wider widths must not measure them: the extra pass is offered
only when the arithmetic already says the seats have room to spare, and a phone
measures exactly the ten widths, in the same order, that it measured before.
Timed with the order alternated so neither carries the warm-up: 10.7ms against
10.4ms on a phone, and +3 to +6ms where the widths are actually used.
And a wide puck on a narrow felt is worse than a small one. The first version
of this 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, reading 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 rather than 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 — and the test pins both ends.
Above the ordinary ceiling the puck takes the larger type as well, which is the
point of the extra width. Nine-handed: an iPad goes 96px/12px to 134px/15px, a
1440px desktop 96px/12px to 140px/15px, and the seats go from 8% of the felt to
12%. Every phone, at every seat count, is untouched.
The sweep is byte-identical to before this change: same six configurations,
same 63 offenders, empty diff.
