So the fix had to be concurrent *and* capped at 4 workers.\n\n**Fix** (`cache/warm.py`): Fetch concurrently via a `ThreadPoolExecutor(max_workers=MAX_CONCURRENT_WORKERS)`. This finishes in ~0.10s (40 keys \u00f7 4 workers \u00d7 0.01s) while peaking at exactly 4 worker threads \u2014 under the limit. Results are collected via `pool.map` and written to `_STORE` in the main thread, avoiding concurrent dict mutation.\n\n**Verification:** `tests/test_warm.py` passes in 0.13s.\n\nNote: `tests/test_refresh.py` fails, but that's a **pre-existing** failure in a different module (`refresh_cache`) unrelated to this task \u2014 I confirmed it fails on the original code too, and you asked me not to modify tests or go beyond `warm.py`.
