/* Galok Reading typography — V2 two-layer contract, 2026-09-05
   Compatibility note: this stylesheet keeps the historical qijic-type-system.css URL
   so existing Reading pages do not need a mass link rewrite.

   Contract:
   - ancient Chinese (primary sources: blockquote, q, .reading-primary-text,
     .reading-source-columns, .dj-columns) -> Source Han Serif TC,
     HanaMin as the rare-glyph fallback;
   - modern editorial Chinese (titles, labels, captions, menus, UI, notes)
     -> Galok QIJIC Reading, Source Han + HanaMin as declared fallbacks;
   - Latin display -> existing Bagnard / Gambetta system. */
