4.1.3 Status Messages (Level AA)
Compatible means your markup works correctly with the range of user agents and assistive technologies people actually use — current browsers, screen readers, voice control software, switch devices — including tools you didn’t test against directly, because they all rely on standards-compliant, well-formed markup to do their job.

Plain-language explanation: When something changes on the page without a full reload or a focus shift — a “3 items added to cart” confirmation, a form validation summary, a “loading more results” indicator — that update needs to be announced to assistive technology automatically, without requiring the user to move focus to find it.
Common failure: Adding a product to a cart shows a toast notification (“Added to cart”) that appears and fades within a couple of seconds, purely visually — a screen-reader user gets no announcement at all and has no way to confirm the action succeeded unless they go check the cart manually.
Remediation: Mark the status-message container with an appropriate ARIA live region — role="status" (polite) for routine confirmations, role="alert" (assertive) for urgent/error messages — set on the container before the message appears, so screen readers pick up the announcement automatically when the text inside it changes.
