# Open invisible-watermark (imwatermark) decoder for detecting the DWT-DCT
# watermarks embedded by Stable Diffusion / SDXL / FLUX. Optional because it
# pulls non-headless opencv AND torch (invisible-watermark declares torch a hard
# dependency, and WatermarkDecoder eagerly imports rivaGan -> torch at import
# time, so the dwtDct-only detect path still needs torch present even though it
# never runs on GPU). So `detect` alone pulls torch -- no need to add `gpu` for
# detection. identify() guards the import and skips the signal when absent.

# Adobe TrustMark decoder -- the open, keyless watermark behind Adobe Durable
