Every placement discussed for every game. Pick a game, pick a layout, and the real game opens with a black box where the ad would go — no mockup, the actual page at your actual screen size. Tap the black box to come back.
Open this on your phone as well as the desktop. The layout is
100vh everywhere — there is no dvh, no svh and no
safe-area inset anywhere in the repo. That means every number quoted on these pages is an
upper bound measured in headless Chrome, and a real handset with collapsing browser
chrome and a home indicator will be tighter. This preview is the only way to close that gap.
Numbers come from notes/ad-mobile-top.md — 888 cells, twelve games × three
phone widths × seven positions, 0 errors. They are quoted at 390×844, and
nearly every cell is a single deal: Cassino read +0 in the matrix and +55
on a re-run.
