  -d '{"model":"nano-banana-2","prompt":"Macro still life of glowing potion bottles on a wooden shelf in a fantasy shop, warm candle light, dust in the air, no labels, no text. Vertical 4:5 composition: the subject fills the upper two thirds and stays inside the central square of the frame. Full-frame cinema still, 100mm macro 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"}'
