/* Green Drain — Subscribe & Save PDP module (US store only; see js/subscribe.js)
   Stacked option cards: One-time purchase (first, default) + Subscribe and save.
   The module ships hidden and is revealed by js/subscribe.js only after it is
   fully wired, so a script failure leaves the classic buy button untouched. */
