/* ============================================================================
   Larkon Toast & Confirm — global notification system (16-May-2026)
   Replaces native alert() / confirm() everywhere.
   Usage from JS:
     Toast.success('Saved'); Toast.error('Failed'); Toast.info('FYI'); Toast.warning('Heads up');
     await Toast.confirm('Delete this?', { title: 'Confirm', variant: 'danger' });
