Automation

Supply ?tag=chrome&device=lab-pc-01 to label and save automatically. Add &json=true&persist=false for local JSON without saving to D1.

GPU calculations, capability limits, selected raster outputs, audio integrity and video codecs are retained. Labels describe your setup; collection does not observe target-site blocks.
