Markdown spec sheets that teach the model how products actually work.
A flip-top skincare tube doesn't unscrew. A dropper bottle doesn't pump. We carry 13 (and counting) product-handling skills — each a structured spec covering motion, dispensing, anatomy, and the artefacts that specific form-factor invites.
