## software/headless WebGL diagnostic baseline

**Not a live-demo GPU characteristic.**

```text
Average FPS: ~8.9–9.6
Renderer: SwiftShader
Status: BLOCKED_BY_DISPLAY_ENVIRONMENT on server
```

## Replay geometries

Earlier probe showed +12 geometries after 3 replays under SwiftShader.
Re-run on production (`npm run perf:replay-stability`): **STABLE** (147 geos flat through 10 replays; +3 after GC pause only).
