Alerts and toast notifications

Show persistent context inline and transient feedback through the toast store.

Start with your first page. Shared ui* providers are registered by createAdmin. Examples belong inside a route template, not the root HTML document. The page and its optional controller load through Atrium’s lazy route registry.

Minimal example

<div class="alert alert-warning">Storage is almost full.</div>
<button type="button" class="btn btn-secondary" @click="$store.toasts.push('Saved', 'success')">Show confirmation</button>

Settings and behavior

  • Alert variants include success, info, warning, and danger.
  • The toast store accepts push(message, tone) and dismiss(id).
  • The shared shell includes the toast stack once.
  • Use role=“alert” for urgent dynamic failures. Avoid announcing every static gallery alert.

Integration notes

Use theme tokens instead of fixed colors. Keep accessible labels on controls. Test with keyboard navigation, both themes, and a narrow RTL viewport.
