/* ═══════════════════════════════════════════════════════════════════════════
   ETHOS AURUM MAISON — STANDALONE STORE PAGES
   Shared chrome + layout for piece.html (the dossier) and checkout.html.
   Added 29 Aug 2026. Loaded after css/eam-tokens.css and css/commerce.css.

   These pages sit OUTSIDE the cinematic scroll — real navigations, a fixed
   top bar, an ordinary footer. The house voice is unchanged: bone ground,
   oxblood ink, serif for feeling, mono for proof, gold only as a hairline.
