/* ══════════════════════════════════════════════════════════════════════════
   MilanoRAD Store — the identity, on top of the shared base (site.css).

   Deliberately NOT the Pharos look. Pharos is a drafting table: Archivo,
   vermilion marks, zero radius, 2px rules. MilanoRAD is the reading room:
   cobalt on ink-blue, Space Grotesk headings over Inter, soft 8px corners,
   hairline rules. Same tokens, so every base component follows without a
   rewrite; the few rules below are where the base's geometry has to give.

/* Self-hosted fonts: the Google Fonts stylesheet was ~74% of a first view's
   bytes and a render-blocking third-party request, and two origins the CSP

   static woff2 per weight the rules below use; other weights fall back to
   the nearest (or a synthesised bold), as they did with the hosted sheet.
