# Toast Rules

@docs/components.md — _Toasts_

## Variants

Use `variant` on `toast()` — never `className: 'destructive …'` or `showErrorToast` / `showSuccessToast` helpers.

| Variant | When |
|---------|------|
| `default` | Success, confirmation (omit `variant`) |
| `error` | Failures; omit `title` for the generic `Error` title |
| `warning` | Caution, rate limits |
| `info` | Neutral info (e.g. clipboard copy) |

## API

```tsx
import { toast } from '@/molecules/Toaster/toast';

toast({ variant: 'error', description: '...' });
toast({ title: 'Saved', description: '...' }); // default
toast({ title: 'Reposted', action: { label: 'Undo', altText: 'Undo', onClick: () => {} } });
```

`toast()` is the only public producer API; `toast.store.ts`, `useToastState.ts`, and the `@/atoms/Toast/*` renderer atoms are Toaster-internal (ESLint-enforced). Custom actions are descriptors (`{ label, altText, onClick }`), never components — the Toaster renders and styles them. Styling: [`Toast.variants.ts`](src/components/atoms/Toast/Toast.variants.ts) only.
