提示词A vertical, atmospheric composition focusing on a single, distant, mottled planet. The planet is delicately swaddled in a swirling nebula composed of warm amber, soft turquoise, and hints of pale gold. The background is a profound, inky navy blue, sparsely populated by sharp, pinprick stars. The lighting is soft and diffused, highlighting the gaseous textures of the nebula. Rendered as a high-fidelity digital painting with a rich, controlled color palette. The planet occupies the central third, allowing the vast, dark sky to act as negative space. Vertical 9:16 wallpaper; main subject in the lower-middle, quiet upper quarter for a lock-screen clock. Full-bleed artwork, no border, no frame, no text, no typography, no logos, no signature, no watermark.
