/* ============================================================
   GYAANSHALA — STORE HOME PAGE (store_listing.php)
   page-specific styles, Task 2 of the 2026-08-29 store-frontend build.

   Ported from the shero / STORE COMPONENTS / cart-drawer / toast /
   sticky-mobile-buy sections of
   docs/design/artifacts/gyaanshala-store.html. Chrome
   (topbar/hdr/nav/ftr/btn/price/eyebrow/gs-wrap/sec-head/badge/course-card)
   lives in gs-brand.css, already linked on every page by includes_top.php --
   this file only carries what is unique to the store pages.

   Deliberately NOT linking gs-blocks.css, for the same reason Task 3's
   gs-page-storecollection.css (same build, read in full before writing this
   file) states in its own header: that file is a verbatim,
   unscoped-beyond-.gsx copy of an older artifact dump 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's chrome. Every selector below is
   self-contained, using `.prod-card` (not `.pcard`) for the product card --
   the exact same class names and values gs-page-storecollection.css uses,
   so cards look identical across the store home and the collection page
   even though the two pages never load the same stylesheet.

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

   does not exist on gs_products -- fabricating one would violate this
   project's own "what is real" rule (see about_gs.php's header comment for
   the precedent), so the ledger is left out rather than faked, and the
