Generate exactly one finished image, never a collage, grid, or multiple variants. An energetic editorial illustration of one adult runner in an orange jacket crossing a midnight-blue city footbridge; long graphic shadow turns into a smooth ribbon echoing the river below. Textured dry brush, precise simple anatomy, architecture cropped into bold blocks, limited but luminous palette. Vertical 3:4, no text. Original visual concept, carefully resolved composition and materials. No watermark. Text-to-image only; do not use previous conversation images as visual inputs.
