/* Minesweeper. Functional layout before the design pass; existing tokens only (spec §7.8, D3).
   Mobile: bar (level, mines left, time, pause), the board in its own scroller, then Flag mode
   and New game, then the result after a game.
   The board keeps the saffron swatch in both themes: covered cells in the field tone, open cells
   in the light tone. Number colors are other swatches' field tones mixed toward their deep tone
   (board-view.js); all derived colors are listed for design review in docs/follow-ups.md.
   Deliberately not the classic look (D3): no bevels, no grey chrome, no LED digits, no face. */
