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: one finished abstract wallpaper. Create exactly ONE widescreen 16:9 image, requesting native 3840x2160 when available. An abstract macro glazed ceramic surface in deep cobalt, one broad low sinuous ridge traversing from bottom left through center to upper right. Glossy turquoise light skims just the crest, deep quiet navy elsewhere, coherent softbox light without literal reflected windows. Smooth solid surface, no cloth, no glass ribbons. Palette #0b2048, #195a9b, #87c4d2. Refined contemporary material and light study with intentional large forms, coherent illumination and clean edges. Make the center crop meaningful on a phone and preserve the composition in 16:10, MacBook and ultrawide crops. Quiet areas should work behind desktop icons and sample text. No text, lettering, logos, watermark, border, people, recognizable objects, tiny clutter, banding or rendering artifacts. Output the finished opaque PNG image only.

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.
