Per Adobe PSD spec, the Image Data Section has ONE 2-byte compression field followed by all planes in planar order (RRR GGG BBB). The previous code wrote a compression marker per channel (4 extra bytes) and used RLE, which third-party viewers parse incorrectly (stretching) and Photoshop rejected. Now writes RAW data with a single compression marker, verified by pytoshop (decompresses to 3x4882x9764).
