Cover is reused Volt card art from examples/gallery/combine-images/preview.webp (wet neon alley + matte-charcoal night-ride radio), pending a true SAM 3 QC isolate — no paid sam3-image run this PR. Job is text-selected isolate: name a region (the Volt radio / cyan lightning chevron) in a cluttered courier desk or wet neon alley. Distinct from Product cutout / BiRefNet V2, which knocks out the whole background. Open the graph from Examples — upload a cluttered scene; Isolate names the object; Text-selected isolate pins sam3-image at auto. Export preview is a local 1024 fit.
