Dreamy Watercolor Portrait Collage

Create a dreamy vertical watercolor photo-collage portrait of {argument name="subject" default="a young East Asian woman"} with {argument name="hair description" default="long wavy brown hair, windswept and tousled"}, bathed in golden-hour backlight. Use a warm beige handmade-paper background with soft watercolor washes, speckled ink splatters, deckled translucent edges, and faint metallic-gold geometric hexagon line accents. Compose exactly 2 photographic portrait panels blended into the paper: the large top panel is an extreme close-up of her face and shoulders, laughing candidly with crinkled eyes, glowing rim light in her hair, loose strands across her face, delicate dangling earrings, and a {argument name="coat" default="beige trench coat"}; the smaller lower panel shows her full body from behind on a wooden lakeside pier at sunset, turning back over her shoulder and smiling, the same beige trench coat belted at the waist, shimmering water and distant hills softly blurred behind her. Frame the collage with exactly 2 botanical watercolor border clusters: one blue flower cluster on the left with large translucent blossoms, small buds, stems, and blue ink droplets; one golden-brown leafy branch cluster on the right with delicate leaves and tiny warm splatters. Overall style should feel romantic, airy, nostalgic, mixed-media scrapbook, realistic photography fused with watercolor illustration, soft focus, warm sunlight, subtle paper grain, no text, no watermark.
