A conversion-focused mobile section that pins a persistent Add to Cart button to the bottom of the screen as shoppers scroll your product page. Keeps the buy action one tap away on small screens, so customers never have to scroll back up to purchase. Slides into view on mobile once shoppers scroll past the main button, then taps straight through to your theme's real Add to Cart form Live variant syncing with the price displayed right in the button, plus a customizable separator character between label and price Automatic sold-out handling with its own label and disabled state, so the bar always reflects current availability Custom background and text colors (or a Dawn color scheme), adjustable button padding, bottom offset, z-index, and four button styles to match your theme It's mobile-only (renders below 749px) and product-page-only The button doesn't add to cart directly; it scrolls to and clicks the theme's main ATC form, which is why "taps straight through to your theme's real Add to Cart form" is in there.
