Style: match the attached base exactly: richly painted aged-ivory bone look, same line weight and lighting, steampunk brass and copper fittings, rivets, gears and gauges, teal glass lenses or vials.

Facing: FRONT, straight on at eye level, the same view as the skull.

Placement: the hat is WORN, pulled DOWN over the cranium. The skull crown is at y=172, centred on x=512. The skull outline is about x=305–720 at y=300.

The hat's band and lower edge must wrap the head and fully cover the cranium silhouette across at least x=295–730. The hat's lowest pixel falls between y=290 and y=325 (target y≈300), always above the brow ridge (~y=385) and the eye line (y=455). Brims may extend wider, up to x=112–912.

Never show the inside, underside, lining or opening. Never perch the hat above the skull with bone visible between brim and crown.

Variety: top hats, bowlers, aviator caps with teal goggles pushed up, gear-banded toppers, copper-plated helmets, pith helmets with gauges, and similar. Vary silhouette and height, but keep every lower edge at y≈300.
