/* Vaucai — self-hosted webfonts (TAC-FIX-04 + TAC-FIX-05).
 *
 * Replaces:
 *   <link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;600;800
 *               &family=Instrument+Serif:ital@1&display=swap" rel="stylesheet">
 *
 * Why self-hosted:
 *  - TAC-FIX-04 (CWE-345, SRI Missing): cross-origin font CSS could not
 *    carry a stable integrity hash (Google ships UA-dependent CSS).
 *    Same-origin removes the need for SRI entirely.
 *  - TAC-FIX-05 (CWE-693, COEP Missing): require-corp blocks cross-origin
 *    resources without explicit CORP headers. Google Fonts does NOT emit
 *    CORP on its CSS or .woff2 — self-hosting from /assets/fonts/* under
 *    our own security-headers snippet (Cross-Origin-Resource-Policy:
 *    same-origin) makes COEP require-corp viable.
 *
 * Inter: rsms.me canonical hinted .woff2, all glyphs in one file per
 * weight (no unicode-range split needed).
 * Instrument Serif: same files Google was serving (latin + latin-ext
 * split) since the upstream repo doesn't publish webfont packages.
 *
 * Cache: served via /assets/* — matches the existing 30d expires +
 * public, immutable directive in vaucai.conf.
