/* ═══════════════════════════════════════════
   S&S SELECTOR — in-cart Subscribe & Save control
   ═══════════════════════════════════════════
   Shared by the cart drawer (parts/cart-drawer.php) and the /cart page
   (woocommerce/cart/cart.php). Two states per line:
     A (one-time)     — a single "Subscribe & Save X%" toggle.
     B (subscription) — "Subscription" pill + delivery-frequency listbox +
                        "Change to a $X one-time purchase" toggle.
   Switching is a blocking AJAX (price + cart-key change), so on interaction
   the live controls are replaced by a green "Updating subscription options…"
   pending line until the host re-renders.

   Mobile-first. No @media (max-width). Tokens only. BEM.
   A11y: Listbox/Variation-Picker pattern (A11Y-PATTERNS.md §LISTBOX). The
   listbox EXPANDS INLINE (not absolute) because the drawer content is an
   overflow:auto scroll container that would clip an overlay.
