/*
 * Shop and backpack panels (Collector's Catalogue design, chosen Oct 2026), shared by the game
 * (shared/shop-panels.js: Points Store, Town Works, backpack, Gear shop) and the proposals page
 * (shop-ui/). Markup and behaviour: shared/shop-kit.js.
 *
 * Part 1 is the panels' structure, states and phone layout (.m, .m-opt, .m-detail, .m-slot...),
 * which every shop-ui proposal reuses. Part 2 is the Catalogue look (.m--catalogue): the shop as an
 * open catalogue, the backpack as the inside of the bag you wear.

/* ---------------------------------------------------------------- backpack: inside the open bag
 * The bag you wear, seen from above with its zip open: the body (.m-bag), the zip around the rim,
 * the pull, and a padded, quilted lining. Slots are stitched pockets with the whole item in view
 * (nothing covers the icon), the stack size on a sewn tag and quality as an enamel pin. Tools sit
 * on an elastic loop sewn behind them. The details are on a luggage tag. The worn
 * pack ([data-pack], as the 3D packs in characters-ac/styles/core.js) picks the materials:
 * none = a linen drawstring pouch, satchel = brown leather, rucksack = green canvas with tan
 * straps, explorer = navy with an orange lining.
