Source and sizing
The 3840 × 2160 JPG is upscaled from the 1672 × 941 original PNG. Upscaling adds pixels, not new detail. Device downloads are cut from the original PNG at the size shown on each card, using the same centered crop as its preview.

Generation prompt
This is the submitted prompt. It can guide a similar image; it does not reproduce identical pixels or establish native dimensions.
Use case: stylized-concept. Asset type: a downloadable abstract background for screens, websites and presentations. Generate exactly one finished opaque widescreen 16:9 image; request native 3840x2160 if available. Create three oversized irregular chalk-white mineral plates separated by broad muted blue-grey seams that converge below the center, with smooth eroded boundaries and subtle dry limestone texture. One large pale plate fills upper-left and center for dark text. Flat abstract mineral cross-section, not watery pigment, no paper tears, no tiny cracks or speckles. Palette #eee9de, #b9c0c0, #7c9394. Keep the composition useful in central landscape, 16:10, MacBook, ultrawide and phone crops. Refined material rendering, coherent lighting, few large forms and calm text space. No text, lettering, numbers, logos, watermarks, border, people, recognizable objects, tiny clutter, accidental marks or distracting artifacts.

The embedded generator hint does not identify an exact model version. No provenance signature verification is claimed. Requested prompt-author reasoning is separate from image-model reasoning.
