/* ============================================================================
   Cascading product-type filter control (shared/_product_type_cascade).
   Trigger button + modal of "open" listboxes. Scoped entirely under .pt-cascade
   so it is portable to every product-type surface during rollout. Uses the
   warm-minimal design tokens (no hard-coded palette). No inline styles.
   ========================================================================== */

/* ── Field wrapper (generic filter bars) ─────────────────────────────────────
   Used by shared/_product_type_filters so the control occupies a filter cell the
   same way the old per-level multi-selects did. .filters-form is a wrapping flexbox
   whose cells size to content, so a DEFINITE width (not min-width) is what keeps the
   cell from growing with a long selection and reflowing the bar. The mobile
   breakpoint's `.filter-group { min-width: 100% }` still takes over on small screens.
   On Seasonality Studio the control is wrapped by _filter_card (grid) instead. */
