crop_image

act imperative

Crop one JPEG, PNG, WebP or AVIF raster in the browser to an explicit source-pixel rectangle (sx, sy, sw, sh). Pass image { mime, base64 } (max 12 MiB decoded). ratio locks the UI for humans; the machine must still send the rectangle in source pixels. Variant URLs are not a second machine Tool. Missing rect is invalid — do not guess a crop. Do not upload.
