~4 minutes and ~$0.50 later the character is in the Lab — mouth, blink, and three idle-life poses, aligned and registered. Runtime cost stays $0/min.
If the mouth/eye boxes need a nudge, use the region helper below on your image, then re-run with the printed --mouth/--eyes values (or edit the character's manifest.json).
Region helper optional
Pick your image, drag the boxes onto the mouth and eyes, copy the command. Runs entirely in your browser — nothing uploads.
