REPRODUCE IT IN 30 SECONDS

Try Ocean. Then Clay.

  1. Before repairChoose Ocean: the price, URL and form ID stay on Sand. A local receipt exposes the mismatch.
  2. Check sold-out behaviorChoose Clay: the old mode still enables submission for the wrong variant.
  3. After repairThe price and ID update. Clay disables submission. Reload a shared variant URL to keep the selection.

Inspect the Shopify section source.

A separate Liquid product section uses native variant IDs, works without JavaScript for selection, and includes setup, test and rollback notes. It is limited to one-time, single-unit purchases with up to 100 variants. It has not been accepted on a real merchant store.
