Sticky add to cart bar on scroll
A compact bar with the product name, price and an add-to-cart button that sticks to the bottom of the viewport once the primary CTA scrolls out of view. Keeps the purchase action always reachable on long product pages.

Hypothesis
If we keep an add-to-cart button visible at all times via a sticky bar, then add to cart rate will increase, because shoppers who scroll deep into the page never have to scroll back up to act.
Notes
Sample entry for layout preview. Allbirds PDP has a long content section below the fold, so the sticky bar carries most mobile ATC clicks.
