Wall Hook V1

implemented unverified

Screw-mounted J-hook: a molded spine drops from the mounting plate into a half-round bay with a tall upturned tip lip. The bay opens toward the plate; almost every profile joint is tangent by construction. Mounts to a wall or the underside of a shelf (orientation note only — geometry is identical).

Built from a real example — orbit to inspect.
