The heron is the clear focal point, with anatomically accurate legs, beak, eye, layered feathers, and a calm alert pose. Surround it with realistic wetland plants, shallow reflective water, distant mist, and warm ivory dawn light. Use an elegant museum-quality observational illustration style with fine linework, subtle paper texture, generous natural breathing room, and no graphic-design elements. The image must contain no writing or typography of any kind: no title, letters, numbers, symbols, panels, article columns, captions, annotations, labels, legends, logos, products, promotional marks, or watermarks.",
