/* ── Number palette (KenKen / Skyscrapers / Suguru) ──────────────────────────
   The shared digit-entry dock rendered by src/ui/numgrid.js. One row of chips
   under the board; the armed chip glows in the accent. No erase chip — a cell is
   cleared by double-tapping it. `--ng-max` (set inline) is the chip count, so the
   row divides the width evenly on a phone and never wraps. */
