/* ============================================================================
 * Component: camp-theme-roboter-arm (0.334.0) — the look of /feriencamp/roboter-arm/ (activity 17189), «Greif den Würfel».
 * Motif from the owner's hero (a wooden servo arm holding a yellow cube, a girl in a coral T-shirt): the cube in the
 * gripper. Hero: warm plywood light with the arm's reach drawn as dashed arcs, eyebrow in coral. Section: a small arm to
 * move joint by joint, and photos from a robot-arm camp. Wood, coral and cube yellow are decoration only (variables);
 * every action stays ROBBO green.
