Prompt d’image
Vertical3:4 abstract signal visualization on nearly black. A narrow luminous structure occupies x20–85%,y4–94%, leaving generous side voids. Its top begins as many parallel near-vertical hairline threads at x25–43%, tiny pink-white nodes connected like a comb. At y27% these strands collect into a broad electric-blue light curtain descending along an S-shaped boundary: bright warm white/orange ridge starts x33%,y39%, dips to x56%,y59%, rises to x75%,y49%, ending near x83%,y54%. Below this upper wave, a second blue curtain sweeps downward to a trough around x51%,y94%, rising back to x77%,y79%. Individual red, cyan and blue nodes trace wave edges. Two thin horizontal elliptical pools of diffused light glow left of center near y75% and81%. Keep upper-right largely empty black. A few tiny nonsemantic micro-labels near edges, not meaningful chart labels. Fine linework, concentrated blue bloom only within curtain, warm ridge as narrow accent, not a broad orange field.
Negative prompt
No landscape, no solid ribbon sculpture, no symmetric sine wave, no filled chart axes, no giant labels, no purple neon, no starry sky, no opaque thick lines.
