   GYAANSHALA — CART (shopping_cart.php / shopping_cart_inner_view.php)
   page-specific styles, Task 7 of the 2026-08-28 brand rebuild.

   Ported from the "cart" section of docs/design/artifacts/gyaanshala-cart.html
   (.shop two-column layout, .items list, .item rows, the empty state, the
   "Often bought together" suggestions grid and the .panel summary rail).
   Chrome (topbar/hdr/nav/ftr) and the shared primitives (buttons, .gs-wrap,
   .eyebrow, .sec-head, .badge, the .course-card family, .price) live in
   gs-brand.css, already linked on every page by includes_top.php -- this
   file only carries what is unique to the cart page.

   SCOPED UNDER .gsx, same convention every other gs-page-*.css file uses:
   every top-level selector starts with `.gsx`, no bare selector escapes it.
   `.banner`/`.crumbs`/`.grid` are re-declared here rather than shared --
   gs-page-courses.css and gs-page-home.css do the same, each page-css file
   owning its own copy so pages can be worked on independently (see those
   files' header comments). Checked against every legacy stylesheet loaded
   by includes_top.php (style.css, new-style.css, responsive.css, custom.css,
   the minified bootstrap/owl/fontawesome bundles) for a bare selector of the
   same name before introducing any class here -- none of .item/.items/.rail/
   .empty/.panel/.pill/.grid/.band/.coupon/.glyph/.sum-row/.sum-total/.savings/
   .gstnote/.paylogos/.trust collide, so no defensive reset is needed beyond
   the .course-card/.quote/.faq ones gs-brand.css already carries (the
   suggestions grid reuses .course-card verbatim).
