+## Spotlight Sandbox
+
+A sample Enact application that demonstrates standalone usage of `@enact/spotlight` for 5-way navigation and focus management.
+
+The sample includes:
+
+- **Container navigation** — nested spotlight containers with visual feedback when a container receives focus
+- **Sandbox** — draggable and resizable spottable controls to exercise spatial navigation
+- **Disappear sample** — focus behavior when controls are disabled, destroyed, or hidden
+- **Hold sample** — press-and-hold Enter on a focused control to trigger hold and pulse events
+- **Test page** — wide and tall controls for nearest-neighbor navigation testing
+
+Use the arrow keys on your keyboard to move focus between controls. Press Enter to activate a focused control.
+
+Each sample runs on its own page so 5-way navigation is not affected by other examples on screen.
+
+Run `npm install` then `npm run serve` to view the app at [http://localhost:8080](http://localhost:8080).
+
+---
+
+This project was bootstrapped with the Enact [cli](https://github.com/enactjs/cli).
