 * Positioned auto-hiding toast (replaces MUI `Snackbar`). Portalled, fixed to the `anchorOrigin`
 * corner; auto-hides after `autoHideDuration` (null disables). Public props preserved (DEC-003).
 * TASK-402.
 *
 * Positioning primitive — no standalone Figma node. The DS severity toast is
 * `StyledDefaultSnackbar` (Figma "System notification-toast"); consumers pass it via `children`.
 * The built-in dark pill is only a bare MUI-compat fallback; radius aligned to the DS 4px token.
