/* ───────────────────────────────────────────────────────────────────
   site.css — shared chrome for every FriendShelf page (home + legal).
   Design tokens, base reset, the atmospheric wash, the header lockup,
   and the footer. Page-specific styles (the hero on index.html, the
   document styles in legal.css) load alongside this file and may override.
   Mirrors the app's design system (DESIGN.md / Color+FriendShelf.swift).
   --container is intentionally NOT set here: each page picks its own
   measure (a wide hero vs a narrow reading column).
