 * pepperaudit v2 — self-hosted font system
 * ----------------------------------------------------------------
 * Eliminates FOUT by self-hosting woff2 files (latin subset only)
 * and providing size-adjusted fallback faces so the layout does
 * not shift when the real font swaps in.
 *
 * Source: Google Fonts CSS API (extracted 2026-05-25)
 *   Fraunces v38, Inter v20, JetBrains Mono v24, STIX Two Text v18
 *
 * Latin unicode-range (matches Google's `latin` subset):
 *   U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA,
 *   U+02DC, U+0304, U+0308, U+0329, U+2000-206F, U+20AC, U+2122,
 *   U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD
 *
 * Files served from /fonts/ on the same Vercel origin (HTTP/2,
 * no third-party DNS roundtrip).
 *
 * Total payload: ~182 KB across 5 woff2 files.

 * 2. Size-adjusted fallback faces
 * ------------------------------------------------------------------
 * Each fallback mimics the metric box of its target webfont so the
 * paragraph height, baseline, and column flow are identical before
 * and after the webfont swap. This keeps CLS under 0.1.
 *
 * Override values were computed via Capsize / fallback-font-generator
 * against the closest system font for each family. They are tuned to
 * within 1-2% so the visible reflow is imperceptible.
 *
 * Naming convention: '<Family> Fallback' so it can be stacked
 *   after the real family in font-family: declarations.
