 * Product tracking screens: variants (option sets in Options > Products, the Variants card of the product form, the stock matrix), batches / expiry, serial numbers.
 * Loaded automatically (templates/boot-material/css/ux/*.css). Markup: includes/functions/tracking_ui.php + includes/scripts/ux/50-tracking-*.js.
 * Uses the design tokens of fm-ui.css (--fm-*). Everything is mobile first: the variant matrix turns into stacked cards below 700px.
