# Exxat DS — no toast

## MUST NOT

- Do **not** use **`toast()`** (e.g. **Sonner**), **snackbar**, or other **transient corner notifications** for product feedback in this app.
- Do **not** add new imports from **`sonner`** or wire **`Toaster`** for feature surfaces.

## Use instead

- **`LocalBanner`** / **`SystemBanner`** for persistent, readable messaging.
- **Inline status** next to the action (e.g. button label change, subtle text under the control, row-level state).
- **Dialog / drawer** confirmations when the user must acknowledge an outcome.

## Why

Toasts are easy to miss, stack poorly with complex layouts, and behave inconsistently with screen readers and focus. This product standardizes on **banners + inline + dialogs**.
