 * FIX: The add-to-cart button is truly disabled (not just styled) when
 * the gate is locked. pointer-events:none stops theme ajax handlers from
 * wiring up their own click listener via jQuery delegation. The disabled
 * attribute stops browser-native click events AND jQuery's :disabled check.
 * Both are required — pointer-events alone doesn't block jQuery .trigger().
