Game view
The game page in an iframe, so every viewport breakpoint is real. The layout switches on the width of .game-container (container queries): stacked below 68rem, mid (board | moves panel) from 68rem, wide (cards | board | panel) from 94rem — about 1120px and 1536px of viewport once the 1rem padding is counted.
