Tool: built-in image_gen, transparent_background=true.

Use case: scientific-educational. Asset type: one reusable galaxy illustration to insert into a precisely plotted scientific figure; generate only the galaxy asset, no graph. A single generic luminous spiral galaxy, isolated on a truly transparent background. Orthographic isometric oblique view from 30 degrees above the disk plane. Projected major axis exactly horizontal, elliptical disk with approximately 2:1 width to height; a warm ivory and soft amber central bulge, delicate blue-white spiral arms, subtle dusty structure, fine realistic star texture, restrained soft glow. Elegant scientific visualization, clear recognizable galaxy at small size. Galaxy centered with generous transparent margins, full object visible, no surrounding unrelated stars. No labels, no text, no axes, no grid, no frame, no black rectangle, no checkerboard. This is a generic schematic illustration, not a depiction of a named real galaxy. Landscape composition.
