## Demonstrated here

- A runnable browser interaction from sample booking to operator queue.
- Queue filtering and visible attention states.
- A simulated delayed event and explicit recovery action.
- Responsive layouts at desktop and mobile widths.
- A local-only runtime with no third-party dependencies.

## Informed by experience

The case reflects general engineering experience with booking workflows, operational dashboards, failure visibility, and recovery-oriented releases. Those patterns are represented as a new clean-room implementation.
