/* System-font stack tuned to match the mockup's editorial look:
   - sans: Geist → Inter → system fallback
   - serif: Instrument Serif → Iowan/Charter/Hoefler system serifs
   - mono: Geist Mono / JetBrains Mono → system mono
   Loading actual woff2 from a third-party CDN is intentionally avoided —
   external font hosts are blocked or slow on mainland China networks. */
