/* ============================================================
   ぎょうざ専門店 ぼんてん - Sannomiya Center Plaza East B1F.
   Gyoza-counter theme: near-white ground, seared rayu accent.
   VARIANCE 6 / MOTION 3 / DENSITY 4. Theme lock: light.
   Accent lock: #a63c14 only. Radius lock: 7px. Wrap 1000px.
   Display: Rampart One (ships 400 ONLY: every display rule below
   pins 400; asking for more would render smeared synthetic bold,
   which this project has shipped twice). Body: M PLUS 2, reused
   from site 06 deliberately: the JA multi-weight catalogue is
   nearly exhausted and the two sites share nothing else.
   Contrast, computed before writing: text/bg 14.84, muted/bg 5.95,
   muted/bg-2 5.28, accent-as-text 6.14, ink-on-accent 6.0. All AA.
