- media color primaries/transfer tags now flow from the FFmpeg probe through VideoParams into Footage::get_colorspace_to_use(); precedence is user override > media tags > project default - export nclc tags derive from the output colorspace (PQ/HLG/BT.2020, P3, sRGB, Rec.601, Rec.709) instead of hardcoded BT.709 - new OCIO Color Grading (Log) node (lift/gamma/gain) and White Balance node (kelvin temperature + tint, HDR-safe) - LUT whitelist extended to 9 OCIO-supported formats - waveform scope gains an RGB parade mode (GPU and software paths) - tests updated for the new colorspace precedence
