/* ============================================================
   GYAANSHALA — STORE COLLECTION PAGE (store_collection.php)
   page-specific styles, Task 3 of the 2026-08-29 store-frontend build.

   Ported from the "COLLECTION PAGE" section of
   docs/design/artifacts/gyaanshala-store-collection.html. Chrome
   (topbar/hdr/nav/ftr/btn/price/eyebrow/gs-wrap) lives in gs-brand.css,
   already linked on every page by includes_top.php -- this file only
   carries what is unique to this page.

   Deliberately NOT linking gs-blocks.css: that file is a verbatim,
   unscoped-beyond-.gsx copy of an older artifact dump (about/instructor/
   blog pages only) that redeclares .gsx .btn / .gsx .topbar / .gsx .art /
   .gsx .pcard etc with slightly different values than gs-brand.css --
   loading both here would bleed conflicting rules onto this page. Every
   selector below is self-contained for this page's own markup, using
   `.prod-card` (not `.pcard`) for the product card so nothing here
   collides with gs-blocks.css's `.pcard` either, in case a future page
   links both files.

   SCOPED UNDER .gsx, same convention gs-page-courses.css uses: every
   top-level selector starts with `.gsx`, design tokens stay on `.gsx`
   (defined once in gs-brand.css, not redeclared here).

/* ---- cart drawer + scrim + toast (store_drawer.php) ----
   Added when store_collection.php's drawer include was uncommented
   (Task 4, 2026-08-29). Byte-identical to gs-page-store.css's own copy --
   that file is only linked from store_listing.php, so without this copy
   the drawer HTML has no positioning/transform rules here and renders
   inline at the bottom of the page instead of as a fixed, off-screen
   panel. Not linking gs-page-store.css wholesale because it also defines
   .prod-card/.pgrid/.empty/.sec with different values for the store home
   page -- see gs-page-storeproduct.css's identical note for the full
   reasoning. */
