Accessibility
- The progress semantics and value accessibility are provided by the underlying Radix Progress primitive.
- Pass a meaningful accessible name, such as aria-label or aria-labelledby, so assistive technology users can identify what the bar measures.
- The decorative border overlays are marked aria-hidden and do not add redundant content to the accessibility tree.
