+Supporting text and the character counter describe the field without becoming
+part of its accessible name. On web, their generated `nativeID` values are
+referenced by the input's `aria-describedby`. Additional IDs passed through
+`aria-describedby` are preserved. On Android and iOS, these descriptions are
+included in `accessibilityHint`, alongside any hint you provide, because React
+Native does not support native described-by relationships.
+
+Error supporting text uses `role="alert"`. Android uses an assertive live region;
+iOS announces changed error messages through `AccessibilityInfo`.
+Custom input renderers should forward the accessibility props they receive.
+Explicit `aria-invalid` values are preserved; when omitted, validity is derived
+from `error` and the character counter.
+Empty fields remain visible to native accessibility before focus and after
+clearing. The field content no longer fades with the floating label.
+
+The filled resting indicator now uses `onSurfaceVariant` and changes to
+`onSurface` on hover. An invalid filled field uses `error` at rest and
+`onErrorContainer` on hover. The focused indicator continues to use `primary` (or
+`error` for an invalid field). Outlined fields continue to use `outline` at rest.
