/* ============================================================================
   assets/css/apps-list.css | Purpose: the /apps/ catalog chrome — redesigned topbar,
   3D hero carousel, the fixed request button and its modal.

   Loaded only by the catalog and the application detail page (via
   views/public/_partials/styles.php). It consumes the locked palette from site.css
   (--k-primary royal blue, --k-secondary crimson, --k-gold gold, --k-* neutrals) and
   defines no colour of its own, so the two files cannot drift apart.

   ── AD SAFETY (contract A1–A11 in AD-SAFETY-REPORT-apps-v5.md) ─────────────
   Nothing in this file targets .ad-slot, .ad-unit, .adsbygoogle or any `<ins>`:
   no transform, no filter, no opacity, no perspective, no will-change, no fixed or
   sticky positioning. The advertising unit keeps its own layout in normal flow.
   Gold is used as ornament and as a glow ONLY — never as the colour of text that has
   to be read, because --k-gold measures 2.25:1 on white.
   ============================================================================ */
