/* Bravest New World — shared design system (v9, apprun.icu family).
   Reading-room paper: warm paper, ink, hairline rules, olive identity
   accent (ink-safe), gold secondary. Fraunces + Inter Tight + IBM Plex
   Mono. Same family as the apprun.icu catalog: no gradients, no glows,
   no glass. Keeps every class name from v8 so tool pages stay stable. */
