# Hero artwork — v0.4

Generated with the built-in image-generation tool. Native masters are 1672 × 941 pixels; the tool did not produce the requested 4K dimensions. Web exports preserve that native detail and add smaller delivery sizes. No upscaling is presented as new detail. The CSS glass composition is resolution-independent.

## Light source prompt

Use case: stylized-concept. Asset type: high-definition full-screen website hero background for Form & Phase, an independent design and application engineering studio. Create a 3840x2160 landscape image, exceptionally crisp, photorealistic physically rendered optical glass. Warm ivory seamless studio backdrop (#FAF9F6). The left 52% is mostly quiet, almost empty ivory space for live black headlines; keep all distinct geometry in the right half. Subject: a monumental single thick optical-glass ribbon, gently folded into two broad intersecting planar surfaces with one flowing rounded bend, architectural and composed. Large sculptural geometry extends beyond the top and right edge; the visible lower bend and a clear open aperture create negative space. Glass must be visibly transparent: doubled beveled edges, transmitted/refracted environment, precise internal reflections, light gathering along edges. A restrained vermilion/amber light traces one edge and projects fine warm caustics on the pale ground in the lower right. Subtle smoky neutral edge contrast makes the form legible on ivory. Cinematic directional studio lighting, tactility, measured restraint, no depth-of-field blur, no grain, no fog, high definition throughout. Composition: visual weight right, quiet left, ample open space, not a collage. No text, no logo, no interface, no spheres, no bubbles, no chrome/metal, no opaque plastic, no rainbow holographic wash. The deliverable is only the background artwork, not a website mockup.

## Dark edit prompt

Use case: lighting-weather. Input image is the edit target for a paired dark-theme website hero. Change only the lighting and environment to a deep near-black charcoal studio (#111512) with a subdued green-neutral cast. Preserve the glass ribbon geometry, camera, framing, empty left half, and relative positions EXACTLY. Keep the glass transparent, with precise bright silver-white bevel highlights, visible internal refraction, and restrained amber/vermilion caustics in the lower right. Left half stays dark and quiet for live ivory headlines. This is glass, not metal. Extreme clarity of edges and caustic detail, no fog, no blur, no noise, no extra objects, no text or UI. Preserve all structural details of the original. Output at the highest available native resolution, ideally 3840x2160.
