/* abisam — index.html styles (Claude-owned)

   This product brands itself. Its palette and components are its own
   and deliberately NOT shared with /assets/css/publishing-site.css, which covers
   the main site pages only (index, contact_us).

   One file per page: this product's pages share ~20 selectors but
   define several of them differently, so a single combined stylesheet
   collides. */
