   BEPCO Studio — Shop styles (loaded only on /shop/ + /shop/<slug>/ via pageCss).
   Ported in spirit from design/mockups/bepco-shop.html + bepco-shop-product.html.
   All colors/fonts reference tokens.css; every class is namespaced `sh-` so it
   never collides with site.css (.hero-*, .section-*, .nav-*, .footer-*, .cb-*).
   Era colors: founding→amber(200,134,10) · operational→porcelain(122,158,138) ·
