# Story 144: Add build timestamp to frontend UI

## User Story

As a developer, I want to see when the frontend was last built so I can tell whether it includes recent changes.

## Acceptance Criteria

- [ ] Inject a `__BUILD_TIME__` compile-time constant via `define` in `frontend/vite.config.ts`
- [ ] Display the build timestamp somewhere subtle in the UI (e.g. bottom corner, header tooltip, or footer)
- [ ] Timestamp should be human-readable (e.g. "Built: 2026-02-24 14:30")

## Out of Scope

- TBD
