/* ---------- the font: self-hosted Ubuntu Mono (Ubuntu Font Licence 1.0) ----------
   The one typeface for the site; `--font-mono` above names it and every page
   links this file, so this is the only place it is declared. It is served from
   OUR OWN origin (/fonts), never a third-party font host: Google Fonts is
   blocked/unreliable in mainland China, and a first-party file needs no extra
   CSP host (`font-src 'self'` already allows it) — see the no-Google-Fonts rule
   in docs/ARCHITECTURE.md. The licence travels with the files: /fonts/UFL.txt.

   Four faces (regular / bold / italic / bold-italic) x two subsets (latin +
   latin-ext). The browser downloads only the faces a page actually uses and only
   the subset whose `unicode-range` its text hits (a page with no latin-ext
   character fetches one ~27KB file). The filenames carry the upstream version
   (`-v19`) so /fonts/* is served immutable (public/_headers) — bump that version
   in the name here (and re-download) if the font ever changes.

   Coverage: Ubuntu Mono has NO emoji and NO CJK, so 👾 / 💬 / Chinese text falls
   through to the system fonts — do not strip the tails off the font stacks. */

/* ---------- the fan's font family (the account tab's #font-select) ----------
   public/js/theme.js reads the versu_font cookie (or localStorage for anonymous
   visitors) in <head> and sets `data-font` on <html> before first paint, so a
   choice never flashes. Each block re-points the ONE type token above; the
   attribute selector out-specifies both `:root` copies (base.css + styles.css)
   whatever the load order. 'default' has no block — it is the :root stack.

   Only 'default' ships font bytes: it is our own Ubuntu Mono. Every other key is
   a DEVICE-GENERIC family the browser resolves locally, so a choice adds no
   download and needs no third-party host (Google Fonts is blocked/unreliable in
   mainland China — see the no-third-party-font rule in docs/ARCHITECTURE.md).
   Keep these keys in step with ALLOWED_FONT_FAMILIES in src/users.js. Every
   stack keeps a generic tail, and none carries emoji / CJK, so those still fall
   through to the system fonts exactly as they did before. */
