# GAL-52: Display Score, Lives, and Stage on the screen using `bevy_ui`

Display Score, Lives, and Stage on the screen using `bevy_ui`.

## Acceptance criteria

- [ ] HUD shows `Score`, `PlayerLives`, and `CurrentStage` as on-screen `Text` nodes via `bevy_ui`.
- [ ] HUD updates each frame the underlying resource changes (use `Changed<T>` filters or run-conditions).
- [ ] HUD is hidden (or not spawned) during `StartMenu`; visible during `Playing` and `GameOver`.
- [ ] Window title is no longer the source of truth for these values (kept only as debug, or removed — pick one).
- [ ] Layout survives window resize without overlapping the play field.

## Integration test hints

- Build `App`, mutate `Score` resource, run schedule one tick, query for the score `Text` component, assert its content includes the new score string.
- Transition into `StartMenu`; assert HUD nodes have `Display::None` or are despawned.
- Visual smoke test via `nix run .#take-screenshots` after resource changes; eyeball that text positions are sensible.
