      "prompt": "Use case: ads-marketing.\nAsset type: raster artwork for a scientific biomedical library cinematic homepage animation, displayed as four cropped life-stage portraits.\nPrimary request: a single extremely high quality wide 3:1 photographic contact sheet, exactly four equal-width vertical areas from left to right representing the human lifespan: (1) newborn baby in a simple soft ivory sleepsuit, comfortably lying on a very dark pillow, upper-body view; (2) teenager around 14 years old wearing a plain dark crewneck shirt; (3) middle aged person around 45 wearing a plain dark crewneck; (4) elderly person around 78 in a plain dark crewneck. The four subjects are different people, a universal human journey. All completely clothed. Exactly one human per quarter, four subjects total.\nComposition/framing: final image landscape approximately 3072x1024. Each subject centered precisely in their own equal quarter, face centers at x=12.5%,37.5%,62.5%,87.5% of image width. Three older portraits consistent head-and-shoulders bust framing, newborn upper body with head near same vertical height. All four heads and shoulders completely contained within their quarter with sufficient margin, no crossing quarter boundaries. Faces prominent, balanced, no accessories. Each facing nearly forward, gentle attentive expression. The background is one continuous uniform seamless dark ink #111b21. No dividers or visible panel edges.\nStyle/medium: lifelike cinematic editorial portrait photography, subtle natural pores and realistic skin, refined premium biomedical research campaign imagery, dignified human expressions, no futuristic armor or effects.\nLighting/mood: soft ivory studio key light, restrained subtle lime/cyan rim light, dark moody background, clear natural faces. Soft falloff to ink at bottom.\nConstraints: no text, typography, labels, logos, watermark, frame, decorative border, diagram, UI, medical equipment, human anatomy cutaways or nudity. Four subjects only, strict four equal areas, no collage mixing between areas. Keep a coherent lens and lighting across the four portraits.",

      "prompt": "Use case: scientific-educational.\nAsset type: cinematic biomedical homepage transition artwork, educational scientific illustration, not a real medical scan.\nPrimary request: a beautifully detailed recognizably early human embryo, approximately 7-8 gestational weeks, shown in side profile with curved C-shaped body, relatively large flexed head, small developing arm and leg buds, delicate visible contours and connection through a short fine umbilical stalk. Embryo curled inside one extremely thin translucent gestational/amniotic-like membrane sphere. Accurate early human embryonic proportions; do not show a mature newborn or a fetus with adult proportions.\nStyle/medium: premium lifelike scientific 3D illustration, delicate semi-translucent warm ivory/blush living tissue, fine capillary detail and soft membranous specular highlights, subtle depth of field, elegant editorial campaign quality.\nComposition/framing: landscape 16:9 image; embryo and membrane sphere centered, occupying about 58% of canvas height, very generous seamless dark ink #111b21 negative space left and right. No other subjects. Close scientific macro lens, eye-level side profile.\nLighting/mood: soft warm transmitted ivory light through tissue, restrained cyan and lime rim glow, dark cinematic environment, beautiful quiet sense of beginning life. A few extremely fine softly defocused particulate points only, very sparse.\nConstraints: no words, no letters, no typography, no watermark, no logo, no labels, no UI, no diagram arrows, no scale bars; no graphic gore or surgery. Not a clinical diagnosis illustration, not a real microscope photograph. No overly developed child, no fully formed large hands. Membrane should be subtle and nearly transparent, not glass ball object or science fiction planet.",
