/* Apple Ball: page shell, game column and canvas (owner: CORE).

   Layout: one portrait column, #game. On phones it is the whole viewport.
   On wide screens it is centered at min(100vw, 62% of the height, 520px)
   and the page background shows around it. The canvas fills the column
   edge to edge (under the notch too, viewport-fit=cover); anything that
   must avoid the notch or home indicator uses the --safe-* tokens.
   #ui sits over the canvas with pointer-events off; UI turns them back on
   for its own buttons and cards (css/ui.css). */
