Vintage Patent: Clockwork Hummingbird

镜头设定：A vintage patent document for an automatic hat-tipping device for gentlemen, styled after late 1800s United States Patent Office filings. The page features precise technical drawings with numbered callouts (Fig. 1, Fig. 2, Fig. 3) showing front, side, and exploded views. Handwritten annotations in fountain-pen ink describe mechanisms. The paper is aged ivory with foxing stains and soft fold creases. An official embossed seal and red wax stamp appear in the corner. A hand-signed inventor's name and date appear at the bottom. The entire image feels like a recovered archival document—authoritative, historic, and slightly mysterious.。建议：分别做硬光和柔光两版，对比后再选定方向更稳妥。
