/* ADV — STORES tab, mobile (flag-gated, ≤1024px).
 *
 * Every rule below is scoped to body.stm-active so the desktop Stores tab
 * (the same SPA when the flag is off) renders byte-identically. The dispatcher
 * in public/js/main.js (renderStoresDispatch) adds/removes the body class.
 *
 * Token vocabulary mirrors public/css/mb-mobile.css exactly (the canonical
 * PR #27 mobile design system). Because index.html does NOT load mb-mobile.css,
 * the tokens are re-declared here on body.stm-active — scoped, not :root, so
 * they never leak into or collide with the desktop dashboard.css cascade.
 *
 * See docs/design/mobile-design-system.md (v0.2) for the full system.
