Brass Doorway Bookmark

Generate exactly one finished image, never a collage, grid, or multiple variants. A beautifully made thin brass bookmark shaped like a simple doorway rests across an open cream paper book. Its hard shadow creates a second doorway on the page, with no readable printing. Extreme material clarity, warm morning light, top-down but slightly angled, square. Original visual concept, carefully resolved composition and materials. No watermark. Text-to-image only; do not use previous conversation images as visual inputs.
