/* ============================================================
   HuaQuan Master V1 — Site-wide adaptation layer (catalog site)
   Extends pilot master-v1.css to non-.content-section page types:
   category listing, news article, key-takeaways, page-hero,
   product cards, standalone section[id] tables.
   Loaded AFTER style.css + home.css + master-v1.css.
   NOTE: most catalog pages have NO <main> tag, so selectors are
   unprefixed; homepage uses hq-hero/hq-main classes and no
   section[id], so it is naturally not matched.
