Layout: `{year}/track_{id}/{frame:03d}.png`, where the frame number matches the index in the original `mcstrack_YYYYMMDD_HHMMSS_N.png` file name and the time index of the corresponding track NetCDF. These are the frames that carry **no morphology label yet**. 2004 is fully labeled and 270 of the 370 tracks in 2005 are labeled; neither is included here. Per-frame metadata — valid time, system motion direction and speed, precipitation-feature shape — lives in the manifests inside the Space, not in this repo.
