/* ── shared.css ───────────────────────────────────────────────────
   Common styles for standalone pages (login, request-access, account,
   404) and server-rendered message pages (lib/message-page.js, the
   edge 403). Imported via <link rel="stylesheet" href="/shared.css">.

   This file must stay in public/. Vite copies public/ verbatim, so the
   /shared.css URL exists in dist/. At the repo root Vite bundled it into
   a hashed /assets/ name for the HTML entries, and every server-rendered
   page that linked /shared.css at runtime got a 404 in production.
