The Announcement component shows an important global message in the application layout, most often in the header area. Use it when users need to see a visible app-wide notice without blocking their current work.
Use it for:
- Global notices: Show a message that should be visible across the app or current layout.
- Header messages: Place billing, maintenance, deadline, onboarding, or product update notices near the top of the UI.
- Optional actions: Add an icon, title, link, variant, or close button when the message needs more context.
- Dynamic announcements: Use the announcement store and global announcement component for app-level messages.
Do not use Announcement for field-level validation, local inline feedback, toast messages, modal confirmations, or critical required actions. Use Alert, Snack Bar, Dialog, or Action Required for those cases.
