/* ──────────────────────────────────────────────────────────────────────────
   Sales Order — POS layout: product catalog pane, cart pane and checkout.

   These rules style markup that lives in child components of SalesOrderForm
   (ProductPane / CartPane / OrderSummary). Blazor's scoped CSS stamps its
   isolation attribute only on a component's own elements, so rules kept in
   SalesOrderForm.razor.css never matched the child markup even under ::deep —
   the catalog rendered unstyled. They live here as global rules instead,
   namespaced by the pos-/cart- prefixes.
