Desk tidy with a tabletop arm

Unconstrained "clean my desk" is research-hard. Constrained tidy is product-possible: colored zones, known object classes, and a fixed camera overhead. The arm picks pens into a cup and pushes paper toward a tray. Great agent skill target: "tidy desk" → run the script.

Curated seed / example for arm kits and sim. Pair with bring-a-bottle for shared grasp primitives.

Keep liquids and laptops out of the workspace.
