We aim for WCAG-conscious contrast, visible focus rings, and a keyboard path to spin (Space, when focus is not in a field). Winners are exposed to assistive technology via a live region, not only the canvas.
The wheel graphic is labeled as an image. Entry editing uses a standard textarea. If you prefer reduced motion, enable it in the operating system — NamesWheel skips the long spin and still selects a fair winner.
Known limit: a canvas wheel cannot expose every slice as individual accessible nodes without harming performance on long lists. The list editor is the accessible source of truth for who is on the wheel.
