   layout.css — in-game screen: header, board, info bars, controls, modals.
   Conventions (see also base.css :root tokens):
     - Controls SIZE TO THEIR LABEL (width:auto) so text is never clipped.
     - Spacing comes from a parent's `gap`, never per-item margins.
     - Sizes/colors/radii/shadows come from --tokens, not magic numbers.
