+## Quick Start: Video Track
+
+`Thumbnail` can read thumbnail cues directly from your video track. Add a `<track>` with `kind="metadata"` and `label="thumbnails"` to your media element.
+
+Mux provides this as `storyboard.vtt`:
+
+`https://image.mux.com/{PLAYBACK_ID}/storyboard.vtt`
+
+<FrameworkCase frameworks={["react"]}>
+  ```tsx
+  <Video src="video.mp4">
+    <track
+      kind="metadata"
+      label="thumbnails"
+      src="https://image.mux.com/lhnU49l1VGi3zrTAZhDm9LUUxSjpaPW9BL4jY25Kwo4/storyboard.vtt"
+      default
+    />
+  </Video>
+  <Thumbnail time={12} />
+  ```
+</FrameworkCase>
+

+      default

+  </video>
+  <media-thumbnail time="12"></media-thumbnail>
+  ```
+</FrameworkCase>
+
+## Anatomy
+
+<FrameworkCase frameworks={["react"]}>
+  ```tsx
+  <Thumbnail time={12} />
+  ```
+</FrameworkCase>
+
+<FrameworkCase frameworks={["html"]}>
+  ```html
+  <media-thumbnail time="12"></media-thumbnail>
+  ```
+</FrameworkCase>
+
+## Behavior
+
+`Thumbnail` resolves an image for the current `time`.
+
+Supported source formats:
+
+- Text track: `<track kind="metadata" label="thumbnails" src="...vtt">`
+- JSON array: `{ url, startTime, endTime? }[]`
+- JSON sprite array: `{ url, startTime, endTime?, width, height, coords }[]`
+
+In React, text-track mode needs `Player.Provider` because it reads track state from the player store. JSON modes (`thumbnails` prop) work without `Provider`.
+
+The component picks the latest thumbnail whose `startTime` is less than or equal to the current `time`, then scales/clips sprite tiles to fit CSS min/max constraints while preserving aspect ratio.
+
+## Styling
+
+Use state data attributes for pure CSS styling:
+
+```css
+media-thumbnail[data-hidden] {
+  display: none;
+}
+
+media-thumbnail[data-loading] {
+  opacity: 0.6;
+}
+
+media-thumbnail[data-error] {
+  outline: 1px solid #ef4444;
+}
+```
+
+## Accessibility
+
+`Thumbnail` is decorative by default (`aria-hidden="true"`). It is intended for visual preview UX (for example, timeline hover previews) rather than primary accessible content.
