Prompt d’image
Portrait3:4 black scientific-interface poster with a giant circular instrument occupying x2–96%,y5–76%. Its center is x50%,y41%. Left semicircle is a dense fan of hundreds of pale electric-blue radial bars and thin spokes, variable outer bar lengths create a serrated edge; inner semicircular ring has fine blue tick marks around a central black void. Right half is mostly sparse ticks around the circumference, with a horizontal red-to-blue volumetric waveform expanding from a thin red point near center toward a tall blue wispy branching profile at right. Preserve sharp vertical split at center between left radial fan and right waveform. Bottom fifth contains compact pale-blue pseudo-technical tables at left and sparse right-angle node diagrams at right. Tiny indecipherable status clusters top corners, a hairline blue rounded border just inside full canvas. Brightest cold light is left perimeter, warm red limited to right center waveform. Fine luminous wires and nodes, grainy dark screen texture, no large headline.
Negative prompt
No full filled circular radar, no concentric target replacing fan, no orange left bars, no readable fabricated statistics, no large UI buttons, no thick border, no landscape.
