  -d '{"model":"grok-imagine-2","prompt":"ROOK, a handmade cardboard knight: a full suit of armor built from corrugated cardboard, brown kraft paper and silver duct tape with visible cut edges and hand-drawn rivets, a bucket-shaped cardboard great helm with a narrow eye slit (no face visible), a tall bright red feather plume, a round cardboard shield painted with a simple tangerine sun, charging on a chestnut horse through a river ford at golden hour, water spray backlit, petals in the air. Composition for a website hero: the subject sits in the right 55 to 60 percent of the frame; the lower-left quarter of the frame stays calm, darker and empty of detail (soft ground, shadow or sky) so type can sit there. Full-frame cinema still, 24mm lens, f/2, shallow depth of field. One motivated key light, strong rim light, real bounce, lifted warm blacks (never pure black), atmosphere (haze, dust or spray) catching the light. Kodak Vision3 500T color, fine film grain, natural skin and material texture, true reflections. Premium game-trailer cinematography, one hero subject big in frame, clean uncluttered edges. No text, no letters, no numbers, no logos, no watermark, no UI, no captions, no signage with writing. Avoid: painterly concept-art look, glowing runes, generic fantasy castles, plastic skin, extra fingers, HUDs, stock-photo smiles, celebrity or franchise lookalikes.","aspectRatio":"1:1","idempotencyKey":"a-new-uuid-per-run"}'
