  "prompt": "Create a refined conceptual editorial cover for an English computer-science research collection. Landscape 3:2 composition. Subject: Two graceful streams of luminous particles narrowing through a transparent throat, a restrained feedback loop of amber light. Museum-quality sculptural still life, physically plausible glass and ceramic, warm ivory background, deep petrol teal and restrained amber gold palette, exquisite soft directional light, sophisticated spatial composition, generous negative space, tactile fine detail. No text, no letters, no numbers, no logos, no charts, no human figures, no circuit-board stock imagery, no neon sci-fi. This is a conceptual illustration, not experimental evidence. Distinct strong visual silhouette legible as a small cover. Full bleed, opaque background.",
