The `Attachment` component displays a file or image attachment, its media, name, and metadata, with optional actions and upload state. Use it for files and images in chat composers, message threads, and upload lists.

## Usage

```tsx
import {
  Attachment,
  AttachmentAction,
  AttachmentActions,
  AttachmentContent,
  AttachmentDescription,
  AttachmentMedia,
  AttachmentTitle,
} from "@/components/ui/attachment"
```

```tsx
<Attachment>
  <AttachmentMedia>
    <FileTextIcon />
  </AttachmentMedia>
  <AttachmentContent>
    <AttachmentTitle>sales-dashboard.pdf</AttachmentTitle>
    <AttachmentDescription>PDF · 2.4 MB</AttachmentDescription>
  </AttachmentContent>
  <AttachmentActions>
    <AttachmentAction aria-label="Remove sales-dashboard.pdf">
      <XIcon />
    </AttachmentAction>
  </AttachmentActions>
</Attachment>
```

## Composition

Use the following composition to build an attachment:

```text
Attachment
├── AttachmentMedia
├── AttachmentContent
│   ├── AttachmentTitle
│   └── AttachmentDescription
├── AttachmentActions
│   └── AttachmentAction
└── AttachmentTrigger
```

Use `AttachmentGroup` to lay out multiple attachments in a scrollable row:

```text
AttachmentGroup
├── Attachment
└── Attachment
```

## Features

- Icon and image media through `AttachmentMedia`
- Upload states: `idle`, `uploading`, `processing`, `error`, and `done` with built-in styling and a shimmer while in progress
- Three sizes and horizontal or vertical orientation
- A full-card `AttachmentTrigger` that opens a link or dialog while the actions stay independently clickable
- Scrollable, snapping `AttachmentGroup` with an edge fade
- Customizable styling through the `className` prop on every part

## Examples

### Image

Set `variant="image"` on `AttachmentMedia` and render an `<img>` inside it. Use `orientation="vertical"` to stack the media above the content.

<ComponentPreview
  styleName="base-rhea"
  name="attachment-image"
  previewClassName="h-auto theme-blue bg-surface dark:bg-background"
/>

### States

Set `state` to reflect the upload lifecycle. `uploading` and `processing` shimmer the title, and `error` switches to a destructive treatment.

<ComponentPreview
  styleName="base-rhea"
  name="attachment-states"
  previewClassName="h-auto theme-blue bg-surface dark:bg-background"
/>

### Sizes

Use `size` to switch between `default`, `sm`, and `xs`.

<ComponentPreview
  styleName="base-rhea"
  name="attachment-sizes"
  previewClassName="h-auto theme-blue bg-surface dark:bg-background"
/>

### Group

Wrap attachments in `AttachmentGroup` to lay them out in a horizontally scrollable, snapping row with an edge fade.

<ComponentPreview
  styleName="base-rhea"
  name="attachment-group"
  previewClassName="h-auto theme-blue bg-surface dark:bg-background"
/>

### Trigger

Add an `AttachmentTrigger` to make the whole card open a link or dialog. It fills the card behind the actions, so the actions stay clickable.

<ComponentPreview
  styleName="base-rhea"
  name="attachment-trigger"
  previewClassName="h-auto theme-blue bg-surface dark:bg-background"
/>

```tsx showLineNumbers
<Dialog>
  <Attachment>
    {/* media, content, actions */}
    <DialogTrigger
      render={<AttachmentTrigger aria-label="Preview research-summary.pdf" />}
    />
  </Attachment>
  <DialogContent>{/* ... */}</DialogContent>
</Dialog>
```

## Accessibility

`AttachmentAction` renders a `Button`, and `AttachmentTrigger` renders a real `<button>` (or your element via `render`). Follow the guidance below so both are operable and announced.

### Label icon-only actions

`AttachmentAction` is usually icon-only, so give each one an `aria-label` describing the action and its target.

```tsx showLineNumbers
<AttachmentAction aria-label="Remove sales-dashboard.pdf">
  <XIcon />
</AttachmentAction>
```

### Label the trigger

`AttachmentTrigger` covers the card with no text of its own, so give it an `aria-label` for what activating it does.

```tsx showLineNumbers
<AttachmentTrigger
  render={
    <a
      href={url}
      target="_blank"
      rel="noreferrer"
      aria-label="Open workspace.png"
    />
  }
/>
```

The trigger sits behind the actions in the stacking order, so an `AttachmentAction` and the `AttachmentTrigger` never trap each other — both remain separately focusable and clickable.

### Keyboard scrolling

An `AttachmentGroup` scrolls horizontally. When its attachments are interactive: a trigger or actions, keyboard users reach off-screen items by tabbing to them. For a row of presentational attachments, make the group itself focusable and scrollable by adding `tabIndex={0}`, `role="group"`, and an `aria-label`.

### Meaning beyond color

The `error` state uses a destructive color. Keep the failure reason in `AttachmentDescription` so the state is not conveyed by color alone.
