A Shaft of Skylight in the Bathroom

Generate exactly one original image, a single finished photograph with aspect ratio 4:5. A compact bathroom finished in matte dusty-blue square tiles with an oval cream freestanding basin on a walnut ledge and one rectangular mirror. A small overhead skylight sends a bright vertical column of natural light onto the basin while the shower corner remains softly shaded. One burnt-orange towel and a plain soap dish provide scale. Plausible plumbing, crisp tile alignment, restrained reflections, quiet architectural photograph, no people. Create an original scene; no borrowed likeness, no collage, no text, no logos, no watermark.
