Find size and variant friction hiding inside add to cart

Separate desire from selection failure

Track attempts on unavailable sizes, changes between variants, size-guide opens, validation errors, and exits after selection. These actions reveal shoppers who want the product but cannot confidently choose it.

Fix sequence

1. Show unavailable options without letting them look selectable.
2. Keep size guidance beside the selector.
3. Explain whether fit is small, true, or relaxed.
4. Offer restock capture on the exact missing option.
