Use case: stylized-concept
Asset type: Square portrait background for a professional profile photo, suitable for circular avatar cropping.
Output: exactly one 1:1 square standalone background, requested 2048 x 2048 pixels.
Primary request: Elegant RAITEC navy portrait backdrop. Keep the central oval occupying the middle 60% smooth deep navy/steel-blue with only a very subtle radial soft studio halo behind where a person's head will later be inserted. Frame the scene along the extreme lower-left and upper-right edges with very large satin folded blue-gray triangular planes and two fine orange edge accents. Quiet diffuse lighting, restrained depth, professional profile photography background. The inner circle of diameter 85% must remain useful after circular cropping. Central face and shoulder region completely free of geometry and bright lines. Deep navy #05345d, steel blue-gray #516f82, #718797, #91a1af, orange #f7a824 and #faba57, neutral white. HEX values are visual art direction. Refined restrained RAITEC corporate aesthetic, crisp folded triangular architecture, no neon or cyberpunk.
Constraints: no person, face, silhouette, head, bust, mannequin or object in the center. No text, logo, watermark, typography, border or circle outline. This is ONLY the background into which a portrait may later be inserted.
