Generate alt-text captions for images with ViT-GPT2 (Xenova/vit-gpt2-image-captioning, ~230MB) entirely on-device, accumulating results in a gallery (caption as the card label, native per-card delete) with copy-caption-to-clipboard + transient copied feedback, remove-single, Clear All, a captioned-count indicator, and a compact add-another dropzone once results exist. Validates JPEG/PNG/WebP/GIF up to 10MB; the model loads lazily on the first dropped image. Consumes none of the promoted image ops. Split out of the tabbed image-studio Caption tool (split-image-privacy).
