## World

| Benchmark | Time | Notes |
|-----------|------|-------|
| new_default | **1.53 ms** | 3×3 tiles with noise (optimized with rayon: was 10.2ms) |
| height_operation | 11.4 µs | radius=10, delta=5 |
| paint_operation | 4.18 µs | radius=10 |
| serialize_json | 5.25 ms | 3×3 tiles |
| deserialize_json | 6.37 ms | 3×3 tiles |
| render_image_scale4 | 1.98 ms | via render_to_image |

## Hot-path Summary

All benchmarks are **below 10ms**. The only candidate (World::new at 10.2ms) was optimized with parallel tile generation via `rayon` — now **1.5ms (85% faster)**.
