/* Donut Bingo — "fits viewport, no scrolling" layout
   This keeps EVERYTHING visible in the viewport by:
   - using a fixed, non-scrolling page (overflow:hidden)
   - giving the content a max height based on viewport
   - sizing the bingo board by the *smaller* of available width/height
   - making the inputs panel internally scroll-free by limiting how much it can take

   Drop in and replace your current CSS.
