MAT_INPUT_TYPE_OVERRIDE

Per-field writable signal that overrides the input's type attribute.

Provided at the mat-input field component level. The button addon's 'toggle-password-visibility' preset writes to it; the field component reads it to compute its effective type.

Optional from a button's perspective — when the button is hosted inside a field that doesn't provide this token (e.g., textarea or a future non-input field), the toggle preset is a no-op.
