Summary
Status changes conveyed without moving focus must also reach assistive technology. Search result counts, cart confirmations, and save notices all qualify. Live regions (`aria-live`, `role="status"`) handle this, but the region must exist beforehand and only its content change for announcements to fire reliably.
Common failures
- Updating the result count visually without announcing it through a live region.
- Injecting the `aria-live` element together with its message, so screen readers never announce it.
