/* ============================================================
   鮨 たかはま - washi and lacquer.

   DESIGN RATIONALE. A ¥10,000+ omakase counter whose own reviewer
   said the EXTERIOR undersells the food (「店構えで少し損をしている」).
   This page therefore has one job: be the first impression the
   storefront is not. Quiet, food-first, nothing loud.

   Palette: washi off-white ground #f6f3ec, sumi ink #26221c, ONE
   accent of deep lacquer crimson #8e2f28 (shu-urushi). Distinct from
   01-tsubaki (DARK warm charcoal ground, ember-ORANGE #e2593a) by
   ground lightness and hue, and from every other light site: 02 bone
   +forest green, 03 cream+amber, 21 paper+shoyu brown.

   Type: New Tegomin display (hand-carved mincho; ships 400 ONLY,
   verified against the Fonts API, so every display rule pins 400 and
   hierarchy comes from size, never from a faked bold) over Kaisei
   Tokumin body 400/700. All-mincho is the high-end washoku register.
   Note: the Kaisei superfamily appears as DISPLAY on 03 (Opti) and
   16 (HarunoUmi); Tokumin here is a different member in a different
   role, taken because the pool of JP body faces with a real 700 on
   Google Fonts is exhausted (documented trade-off, not an oversight).

   Radius lock: 0 everywhere, like the edge of a hinoki counter.
   Accent rules: #8e2f28 passes as text on bg (7.32) and bg-2 (6.64);
   buttons take --accent-ink #faf7f0 (7.59). All computed, not eyeballed.

   Chrome variant: minimal-rail nav / split reserve / strip footer.
   Checked against the ledger: 03 rail+band+strip, 06 rail+split+
   centred, 09 rail+centred+2col, 19 rail+centred+centred. This
   combination (rail+split+strip) is unused.
