- On the gallery, show the previous or next photo. In the finish and size groups, move the selection.
- Tab
- Move from the gallery to thumbnails, variants, the stepper, add to bag, and the accordion.
- EnterorSpace
- Choose a thumbnail, toggle an accordion section, or add to bag.
- The gallery is a labelled carousel region with slide groups; hidden slides are aria-hidden and the counter is live.
- Finish and size are radiogroups with roving tab stops, like native radios. Sold out sizes stay selectable and say Sold out in text.
- Add to bag reports aria-busy while adding and announces the result; failures show Try again on the button itself.
- Accordion buttons sit in headings with aria-expanded and aria-controls.
- Review bars are hidden from assistive technology and each row carries a text label with its count.
- The gallery follows the pointer 1:1, rubber-bands at the ends, projects the flick with momentum, and hands the release velocity to the spring.
- Changing finish crossfades each photo in place; the thumbnail ring slides between thumbnails.
- The price rolls when size changes. Add to bag morphs through Adding and Added to bag without changing width while the bag icon tilts and its count rolls.
- Review bars fill once when they scroll into view; accordion sections open on a critically damped height spring.
- Reduced motion jumps the gallery, removes travel and blur, and shows final bar widths.
- Above 980px the gallery sticks beside the info column; from 680px to 980px both columns share the width equally.
- Below 680px everything stacks: a square gallery with a four up thumbnail row, then the info.
- Under 420px the reviews summary stacks above the bars. Gallery arrows appear on hover only; touch uses swipe.
- The gallery drags one track with a motion value; only transform changes during a swipe.
- The first photo uses priority loading; the rest load lazily at the gallery's size.
Notes for AI
Give your coding assistant the Markdown reference instead of screenshots.
- Use as the main product page. Put finish specific photos on each finish so the gallery always matches the chosen swatch.
- Return your cart request from onAddToCart so the button shows real pending and error states.
- Keep sections to three or four; long policies belong on their own page.
