Stylish Nobunaga Ukiyo-e Portrait

Create a vertical 2:3 Japanese ukiyo-e inspired anime illustration of {argument name="character name" default="Oda Nobunaga"} as a stylish mature warlord, shown from the waist up in a dignified three-quarter portrait. He has a tall messy black topknot with loose strands and a gold hair ornament, one visible ear, and his face is intentionally obscured by a centered opaque tan rectangle covering the full facial area from forehead to chin. Dress him in ornate Sengoku-era armor and layered kimono: a high black collar with gold trim, dark navy and black lamellar chest armor with red cords, two large gold chrysanthemum-like crests on the chest, red brocade shoulder panels with floral patterns, cream sleeves with purple and gold cloud motifs, dangling red tassels, and two decorated sword hilts crossing at the lower front. The background is parchment cream with an orange-red setting sun disk behind the figure, fine black ink landscape lines, stylized white cloud streaks, purple-gray ink wash clouds, halftone dot textures, and a small Japanese castle in the lower left distance. Frame the composition with thick black Art Nouveau-style rounded corner borders and spiral ornaments: exactly 6 prominent black spiral/circle ornaments, with 2 at the upper left, 2 at the upper right, and 2 at the lower corners. Use detailed linework, muted antique colors, gold accents, print texture, manga-meets-traditional-Japanese-poster aesthetics, and dramatic heroic posture. Add a small signature and date in the lower right reading {argument name="date text" default="June 2, 2026"} and {argument name="signature text" default="Oyagi"}. No other text, no watermark, keep the central tan face-cover rectangle perfectly flat and untextured.
