During the resolution-unify epic (#22), the scaler's HDR/10-bit path was verified only by argv unit tests + tonemapping=none — the real NVENC encodes on the RTX 4080 used 8-bit bt709 sources (no HDR clip available). Confirm a real HDR (smpte2084/PQ) source upscaled via the libplacebo path stays 10-bit (yuv420p10le/main10) with no unintended tone-mapping. Files: _decode_filter_args libplacebo branch, calc_encode_params HDR detection. Verify: encode a real HDR clip with target_res set; ffprobe pix_fmt + color_transfer.
