/* LIWA's own typefaces, self-hosted.
 *
 * Production audit 2026-09-19. Google Fonts loaded on EVERY student page with a
 * `preconnect` that fires before any interaction, disclosing every child's IP
 * address and user-agent to Google on page load — before the student has done
 * anything, and whether or not they ever use the app. For a platform whose users
 * are 10-to-15-year-olds under the DPDP Act, a third-party request that happens
 * before consent is the kind of thing a privacy notice has to account for.
 *
 * It was also unnecessary: all three families were ALREADY committed in the repo
 * at frontend/src/assets/fonts/, and the nine admin pages have self-hosted from
 * static/fonts/ since the Ledger Desk pass. Only the student SPA was still
 * fetching them over the network.
 *
 * The declarations below are the admin theme's, verbatim, plus Space Mono and
 * the Devanagari subset the admin does not use. Baloo 2 and Nunito are VARIABLE
 * fonts, so one file covers the whole 400-800 range the SPA asks for; Space Mono
 * is static, hence one file per weight. `unicode-range` keeps the split subsets
 * behaving exactly as Google's own CSS did — a browser downloads latin-ext or
 * devanagari only when the page actually contains those characters.
 *
 * WHAT THIS DOES NOT COVER: the six non-Bright THEME packs each declare their own
 * `googleFontsUrl`, loaded at theme-activation time by applyTheme.ts. Those still
 * reach Google, which is why main.py's CSP keeps its fonts.googleapis.com and
 * fonts.gstatic.com allowances. They fire only for a student who has chosen a
 * theme — an action, not a page load — and self-hosting fourteen more families is
 * its own piece of work. The default Bright theme, which is what every student
 * gets until they change it, now makes no third-party request at all.
 *
 * Served from /static/, so `templates/spa.html` links it directly. Deliberately
 * NOT bundled through Vite: spa.html is a Jinja template FastAPI renders, and the
 * committed source of these files is frontend/src/assets/fonts/ — never
 * static/app/assets/, which is a build artifact whose names change every build.
