Using REFERENCE_0 and REFERENCE_1, create a clean ethnographic archive plate focused on the ceremonial hat. Use REFERENCE_0 as the historical Tibetan context and silhouette reference, and REFERENCE_1 as the color, material, and ornament reference for the hat. Isolate and reconstruct the hat as a museum-style object study, removing the seated body as the main subject. Present the hat on an off-white document page as a scholarly catalog sheet in Chinese with small romanization. Add 8 numbered callouts around the object with fine dashed leader lines, each pointing to a specific structural detail.
