A second header chip cycles the felt shape, so table and seat treatments can be
compared together on a device rather than argued about from screenshots.
- Oval: ellipse fitted to the container. Seats step by equal angle, because even
horizontal spacing on a deep ellipse always bunches the middle three.
- Arena: a circle wider than the screen. The left and right lobes fall outside
and are clipped, trading side space nobody uses for a broad, shallow top arc.
The arc drop from crown to outermost seat falls from roughly 143dp to 70dp at
384dp wide, so seats spread across the full width instead of stacking.
- Stadium: racetrack. Flat across the middle, curving only at the ends.
Shape and seat arc are one decision, not two: seats are placed on whichever
curve the felt is drawn from, so they cannot drift off it the way hand-picked
lanes did. On the shallow shapes seats space evenly by x, which is exactly where
that works — the vertical differences are small enough to read as a gentle curve.
Tests cover all three shapes at every supported width for overflow and
collision, and assert arena flattens the arc relative to oval.
