Build a ridiculous contraption around my real portrait

Use an authorised [UPLOADED PORTRAIT] as the base for one wide still-image collage of a harmless, absurd chain reaction. Preserve the visible person's face, hair, hands, pose and clothing; edit only unoccupied space and an empty tabletop area if present. Do not invent a table if the source has none: ask for another image or use clear background space instead. Arrange three supplied [APPROVED OBJECTS] in a visually traceable sequence: a rolling object triggers a lever, the lever releases a harmless prop, and that prop leads to [SILLY FINISH]. Show contact points, consistent gravity, cast shadows and modest drawn motion arrows. This is a playful illustration, not a working construction diagram or evidence of an event. Return one image and optionally identify the three beats. Reject unsafe mechanisms, extra hands, private background text and altered identity. If exact facial pixels matter, mask and composite the untouched source face rather than relying on this prompt alone.
