    "prompt": "Use case: scientific-educational.\nAsset type: a premium biomedical library website's closing cinematic background, widescreen 16:9 landscape, preferably 1920 x 1080.\nInput images: the most recent reference image (glowing wireframe human with golden concentric geometry) is the composition and visual idea reference. The user wants a new medically focused adaptation, not the existing website's ocean, cosmic portal or distant walking person.\nPrimary request: create a sophisticated three-dimensional translucent human anatomical figure in the center, front-facing from head to upper thighs with arms gently angled out, inspired by the reference's luminous mesh human. It must read immediately as human medicine and biomedical anatomy. Beneath its fine cyan-teal contour and geometric wire mesh, subtly visible ivory skeletal landmarks and an anatomically placed heart and branching vessels. Warm pale-gold illumination from within the chest, carefully restrained rather than a blinding flare. Surround the figure, mainly along the LEFT AND RIGHT OUTER THIRDS and upper/lower corners, with recognizable MEDICAL components: a detailed anatomical heart with coronary vessels, brain with cortical folds, translucent lung lobes and bronchial tree, liver, delicate red/blue vascular branches, a DNA helix, a cluster of translucent cells, soft magenta histology-like tissue islands, and a few grayscale CT/MRI cross-sections embedded as luminous thin medical imaging planes. These elements share the same physical lighting and fine detail, arranged as an elegant layered scientific atlas around the central human, with different apparent scales and optical depth. A restrained few concentric measurement arcs echo the reference, but are subordinate to the anatomy; no generic energy waves filling the composition.\nScene/backdrop: deep ink navy and blue-green, matching a dark biomedical website (#111a20). Sophisticated teal/cyan rim lighting, muted ivory and warm-gold anatomical highlights, restrained magenta in tissue and cells. Premium scientific cover illustration, convincing dimensional materials, finely detailed translucent membranes and branching tissue, controlled depth of field. Not a poster collage or separate card grid.\nComposition/framing: broad widescreen, all major subjects comfortably within frame. Central figure slightly softer/lower contrast than the detailed surrounding anatomy. Preserve a visually QUIET DARK HORIZONTAL AREA through the central 60% of the image at 40–65% image height, where the website overlays its large white title and lime call-to-action. This space may overlap the subtly visible torso, but no bright chest glare or dense anatomy over that title zone. Keep outer medical elements distinct and legible. No text should be drawn.\nAvoid: ocean, mountains, clouds, stars, cosmic portal, a tiny person walking away, fantasy scenery, spiritual symbols, extra arms, clinical photographs, gore, blood spills, UI panels, written numbers, letters, labels, logos, watermarks, magazine typography. The medical imagery is an artistic illustration, not diagnostic data.\nText: none.",

Create an original 16:9 landscape composition, ideally 1792 x 1024 pixels, with extraordinarily convincing physical depth and scientific editorial image quality. Molecular world viewed from within: a large three-dimensional DNA double helix winding diagonally from dramatically cropped near foreground at lower left into the middle distance, interwoven with a separate precisely folded protein structure made of translucent teal alpha-helix ribbon coils and smooth beta-sheet ribbons. DNA has two continuous pearl-cyan beaded sugar-phosphate backbones and paired delicate copper-gold molecular rungs; distinct beadlike atoms join in an intricate physical structure. The central composition forms an open spiral aperture with deep dark space beyond, allowing a camera push into the helix. Materials resemble subtle translucent molecular glass and softly glowing wet pearl rather than shiny toy plastic. Deep ink navy #111c21 background with atmospheric cyan, muted gold, tiny lime glints, isolated floating molecular motes. Sophisticated macro lens, wide-aperture depth of field with one foreground strand dramatically defocused, center structure crisp, soft cinematic volumetric rim lighting and believable occlusion, generous negative deep background. Detail-rich layered depth, striking sculptural scientific cover-art quality. No letters, no text, no labels, no logos, no watermarks, no borders. Do not reproduce an existing magazine cover.

Large translucent cells in the near foreground show delicately folded phospholipid membranes, fine reticulated cytoskeleton, intricate mitochondria and endoplasmic-reticulum-like organelles, and textured luminous nuclei with small nucleoli. Each cell is a believable soft irregular three-dimensional volume with moist subsurface scattering, some cells forming a visible cleavage furrow and pairs of daughter cells. Many dozens of progressively smaller cells fan and branch into the deep middle and background, conveying rapid proliferation into tissue. One sweeping diagonal stream of cells across frame creates an expansive sense of scale; larger sharply focused cells across the central area, foreground edges dramatically defocused, background fades into depth. Rich fluorescent magenta nuclei, translucent cool cyan cell membranes, tiny pale-gold organelle highlights, delicate lime micro-glints, deep dark ink navy negative space.
