/* ── Suguru (Tectonic) ───────────────────────────────────────────────────────
   The play chrome (.q-chrome / .q-stage / .q-foot) is the shared shell from
   queens.css; the board borrows Queens' riso region palette (--q-r0…--q-r8) and
   its edge tokens (--q-edge / --q-grid) so a region reads as a block of ink with
   a thick rule between neighbours. Below is Suguru's own: the coloured grid, the
   digits (bold ink for givens, accent for what you write), and the number dock
   layout in the foot. */
