  "prompt": "Create a square t-shirt graphic design with the following concept:\n\nTitle: Feral Echoes\nSlogan: Whispers beneath cracked ink\nVisual style: chalk sketch with layered collage and subtle scanlines\nMood: feral sinister tension\nCore concept prompt: A layered collage composition featuring a chalk sketch style skull intertwined with a totem mask, overlaid on a nordic frost palette background. The image is textured with cracked ink and ink splatter effects, accented by faint laser grid lines and horizontal scanlines to add a cyber-analog atmosphere. Typography combines bold condensed minimal sans font with psychedelic lettering arranged prominently below the image displaying a mysterious slogan. Mood evokes a sinister, feral tension with careful low energy flow and medium complexity, all elements centered for print clarity.\n\nHard constraints:\n- Keep composition centered and shirt-print friendly.\n- Use high-contrast, clear forms suitable for print.\n- Any text must be large and easily readable.\n- Exclude all forbidden elements: real brand logos, celebrity likenesses, political slogans, explicit content, tiny unreadable text\n- Do not include real brand names/logos, celebrity likenesses, copyrighted characters, political campaign slogans, hateful content, or explicit content.\n\nOutput a clean standalone design graphic, no mockup, no watermark, no background scene.",
