/*
 * Storefront PLP (product listing page) styles — docs/webshop 06 §6 + §15.11.
 *
 * Page-scoped CSS loaded only by the PLP (host per-page asset pattern). EXTENDS
 * shop-tokens.css / shop-components.css (sh-* system) — references --sh-* /
 * host tokens, never hardcodes brand colors. Mobile-first: facets are a
 * bottom-sheet drawer on <lg and a sticky left rail on lg+; the results grid
 * reuses .sh-grid. Progressive enhancement — everything is usable without JS;
 * the drawer open/close + grid/list toggle are JS niceties (P2.5), and the
 * layout degrades to the facet form stacked above the grid when JS is absent.
 *
 * Breakpoints match shop-components.css: 576 / 768 / 1024(lg) / 1280.
 * Contrast verified against tokens (AA). Hand-authored, ?v= cache-busted.
