/* ==========================================================================
   VolTrack webfonts — self-hosted
   --------------------------------------------------------------------------
   These faces used to load from fonts.googleapis.com and api.fontshare.com.
   Authenticated pages can contain student data, and a CDN-hosted font handed
   those third parties an IP address + User-Agent on every single pageview by a
   logged-in student. Serving the files from our own origin removes that
   exposure completely and kills two render-blocking third-party round-trips.

   Do not replace these with CDN links. The CSP no longer allows ANY font host,
   so a reintroduced <link> will fail silently in production.

   Typography is locked by DESIGN.md — display = Cabinet Grotesk (700/800),
   body/UI = Geist (400–700), data = Geist Mono (400–500). This file changed
   only where the files are served from, never which fonts are used. The
   font-family names are identical to what the CDN declared, so every
   font-family declaration in ui.css / app.css / polish.css / landing.css keeps
   working untouched.

   Licenses (files live in /public/fonts):
     - Geist, Geist Mono — SIL Open Font License 1.1. Full text: fonts/OFL.txt.
       Copyright 2024 The Geist Project Authors.
     - Cabinet Grotesk — ITF / Fontshare Free Font License,
       https://www.fontshare.com/licenses/itf-ffl
   Neither license requires visible attribution in the UI. See fonts/README.md.

   unicode-range is what makes subsetting work — the browser only downloads a
   file if the page actually contains a codepoint in its range. Never strip it.
   Subsets intentionally omitted: cyrillic, cyrillic-ext, and Geist Mono's
   symbols2 (box-drawing). Vietnamese is kept because student names need it.
