.tip

A spinner that turns into "Saved" only happens visually, so a screen reader says nothing at all. Text inside a live region does get read out, as long as the region was already in the DOM, and empty, when the text arrived.

<p role="status">{status}</p>

role="status" means aria-live="polite", so it waits for a pause in speech. Render the element empty on first paint and set status when the request finishes. If the element and its text mount together, most screen readers stay quiet.
