    "name": "earth",
    "prompt": "Use case scientific-educational. Create an extremely beautiful premium natural history exhibition hero illustration of planet Earth with a clean quarter wedge removed to reveal its interior. Landscape 3:2. Earth globe occupies the RIGHT 74 percent, with the LEFT 26 percent nearly black empty negative space for website text. Sophisticated photoreal 3D museum model, suspended against absolutely flat charcoal black #101110, no stars or galaxies. Cool muted blue oceans and subdued realistic continents on the round outer shell, very thin crust rim; cut plane is visible facing viewer and lower-left. Four distinct concentric material regions, scientifically considered proportions: mantle extends from the very thin crust down to core boundary at about 55 percent of planet radius; outer core metal surrounds an inner solid sphere of radius about 19 percent of planet radius. The thick mantle is dense matte rocky deep umber, sienna and ochre, NOT liquid lava. The liquid outer core is burnished orange-copper metal, restrained glow, subtly rippling only in that zone. The solid inner core is pale warm gold metal with subtle crystalline texture. Strong geological material texture and quiet cinematic chiaroscuro, copper warmth in the cut face, a fine cool atmospheric edge at top. Realistic sphere and depth, luxurious restrained typography-ready composition, soft boundary into black. NO text, no labels, no arrows, no grids, no watermark, no exploded layers, no visible flames, no open caves or dinosaurs. Explanatory model rather than actual underground photograph. The geological layers must be continuous nested spherical shells, not stacked flat disks."

    "name": "strata",
    "prompt": "Use case scientific-educational. Panoramic cinematic geological diorama for a museum website: a rugged austere mountain landscape and the layered solid crust beneath it, shown as an exposed cross-sectional rock face. Landscape 3:2. Top quarter has sharp charcoal mountain peaks, a tiny cold blue-gray dawn sky, subtle hazy distant ridges. Beneath, enormous finely textured bands of sedimentary rock, fractured dark metamorphic rock and massive crystalline bedrock descend through most of the frame. Compelling irregular diagonal strata, deep crevices, dense SOLID rock all the way down, with very subtle warmer copper mineral accents at the lowest edge. Premium realistic geological 3D cutaway, tactile highly detailed stone, vast scale and solitude, restrained palette of slate, charcoal, dark ochre, dusky brown. Almost black #101110 edges for blending into a dark exhibition page. No molten mantle, no glowing river of lava, no tunnel, no people, no numbers or labels, no fossils or fantasy, no text. An artistic crust cross-section, not a real measured borehole."

    "name": "granite",
    "prompt": "Use case scientific-educational. Premium natural history museum specimen photography style. A single large rough angular hand specimen of GRANITE, suspended on completely flat near-black charcoal #101110 background. Full rock in frame centered with generous negative space. Precisely realistic visibly coarse interlocking mineral grains: pale gray translucent quartz, creamy white and muted pink feldspar, sparse black shiny mica flakes. Dense massive rock with rugged fractured surfaces, no crystals sticking out like geodes, no holes. Dramatic soft raking light from upper left revealing grain texture, restrained warm reflection below, exquisitely detailed realistic geology, luxurious editorial object portrait. Landscape 3:2. No pedestal, no hand, no ruler, no labels, no logos, no text, no glow. Illustrative specimen image only, not a claimed catalog sample."

    "name": "basalt",
    "prompt": "Use case scientific-educational. Premium natural history museum specimen photography style. A single large rough angular hand specimen of BASALT, suspended on completely flat near-black charcoal #101110 background. Full specimen centered with generous negative space. Precisely realistic dense dark charcoal to dark gray very fine-grained volcanic rock, fine compact texture, irregular fresh broken faces with a few tiny pores and no prominent large mineral grains. This is massive basalt not a pumice, not shiny obsidian glass, not crystalline granite, not a column cluster. Dramatic soft raking light from upper left revealing dense subtle surface texture, restrained copper rim reflection, exquisite geological realism, luxurious editorial object portrait. Landscape 3:2. No pedestal, no hand, no ruler, no labels, no logos, no text, no glow. Illustrative specimen image only, not a claimed catalog sample."

    "name": "peridotite",
    "prompt": "Use case scientific-educational. Premium natural history museum specimen photography style. A single rough angular PERIDOTITE rock hand specimen, a typical upper mantle rock dominated by olive-green granular olivine with darker green-black pyroxene, dense and visibly crystalline interlocking grains, angular naturally fractured uneven surfaces, weathered muted brown outer edge in places. Scientifically believable rock, not emerald gemstones, not moss, no geode or quartz spires. Full specimen centered in landscape 3:2 with generous negative space on a completely flat near-black charcoal #151310 background. Dramatic restrained museum raking light, realistic high detail and tactile mineral grain, subtle warm rim reflection. No labels, no words, no hand, no ruler, no pedestal, no fire or flowing lava, no diagram. An illustrative upper mantle specimen portrait, not a sample collected from the lower mantle or the Earth's core."

    "name": "inner-core",
    "prompt": "Use case scientific-educational. An exquisite conceptual 3D museum model of the Earth's SOLID inner core, alone as a coherent spherical metal mass against a completely flat near-black brown #17110e background. The sphere occupies central 65 percent in a landscape 3:2 composition, whole sphere in frame with negative space. Realistic dense iron alloy material, subtle faceted and crystalline grain structure across the solid surface, irregular fine metallic texture, soft champagne gold on illuminated upper left face grading into burnished copper and near-black lower right shadow. A thin restrained amber rim glow communicates extreme heat artistically, not actual visible surface observations. Cinematic quiet light, premium science museum object study, tangible heavy solid material, no flowing lava, no cracks filled with magma, no melting drips, no solar flares, no flames, no floating fragments, no exaggerated giant crystals. No text, no labels, no arrows, no human, no spacecraft, no watermark. A speculative explanatory model, not a photograph or a claim about known visible core texture."
