/* ADSUR homepage — rebuilt from adsur_homepage.html (2026-09-09 mockup).
   This "home" library is attached ONLY on the /adsur route (page--adsur.html.twig),
   which strips the theme's dark "global" library (see landing_page_page_attachments_alter),
   so it is safe for these rules to target body/html/a/h1 unscoped — nothing else
   on the site loads this stylesheet. The shared nav reused on cloud-infra node
   pages (127-129/138/139/224) uses the separate, class-scoped home-nav.css instead. */
