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. The centerpiece should be one large three-quarter underside view of the hat. Also include exactly 4 supplementary views/details: 1 side-profile wearing sketch with a faint line-drawn bust, 1 underside interior view, 1 top-down view, and 2 square close-up material swatches. Add exactly 4 thread-color samples near the lower right: blue, red, white, and yellow. At the top center, add the large title {argument name="headline text" default="Tang Xu Hat"} with the romanization {argument name="romanization" default="(thang zhwa)"} beneath it, plus a smaller subtitle describing it as a summer ceremonial hat of high-ranking Tibetan monks. In the upper left, add a boxed metadata panel with multiple short Chinese fields, and in the upper right add a plate number reading {argument name="plate number" default="Plate No. 27"}. At the bottom, add one bordered note paragraph in Chinese. Overall style: meticulous archival infographic, anthropological catalog illustration, historically informed, precise woven texture, ivory-gold base with blue and red ornament, elegant print layout, thin rules and decorative divider marks, high-detail object rendering on a plain paper background.
