  "prompt": "Create a refined conceptual editorial cover for an English computer-science research collection. Landscape 3:2 composition. Subject: Two interlocking glass ledgers whose individually aligned sheets create a visible impossible gap when combined, one amber joining pin restoring the invariant. 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.",
