   SELF-HOSTED FONTS - added 2026-08-05
   Replaces a remote @import from Google's font service, which disclosed every
   visitor's IP address to Google (security review 2026-07-31, finding 3)
   and broke the site's typography on networks that block Google.
   Files live in /assets/fonts/ and are served from our own domain, so the
   site now makes ZERO external requests. Per RULES_tech 25.

   These are VARIABLE fonts: one file carries every weight, so the whole
   declared range works with no extra downloads. The browser fetches only
   the character sets a page actually needs (unicode-range below), so an
   English page pulls ~107 KB and never touches the accented or Greek files.
