EXCLUSIVE WRITE BOUNDARIES:
You exclusively own:
- `tests/unit/test_map_style_assets_integrity.py`

YOUR MISSION:
Develop automated unit test suite `tests/unit/test_map_style_assets_integrity.py` verifying the integrity and quality of all 30 map style asset packages.

TEST REQUIREMENTS:
1. Verify that all 30 style folders exist under `client/webapp/assets/map/styles/`.
2. Verify that each style folder contains:
   `floor.png`, `wall.png`, `path.png`, `liquid.png`, `props.png`,
   `floor_normal.png`, `wall_normal.png`, `path_normal.png`, `liquid_normal.png`.
3. Verify that every file is a valid non-empty PNG with valid PNG magic header (`\x89PNG\r\n\x1a\n`).
4. Verify image dimensions (floor/path/liquid either 64x32 or 128x64 px; wall 128x128 px).
5. Verify normal maps have Blue channel dominant ($B > 128$) conforming to tangent-space lighting shader standards.
6. Verify file size efficiency: individual tile files < 60 KB, total asset folder size < 10 MB.
7. Run `pytest tests/unit/test_map_style_assets_integrity.py -v` to ensure 100% pass once worker produces the assets.

OUTPUT REQUIREMENTS:
Write your handoff report to `c:\Projects\FreeExile\.agents\teamwork\test_writer_m2\handoff.md`.
Send a message to orchestrator_14 when complete.
