Editorial technology hero background for a B2B AI advertising assistant. Wide panoramic composition, pearl white and navy architecture, soft lavender and peach glass flowing ribbons concentrated only on right half, sophisticated photorealistic 3D material with studio daylight and delicate shadows. Left 55% clean white negative space for dark HTML headline. No people, no faces, no mascot, no text, no letters, no numbers, no logos. Visual metaphor of calm organized workflow, minimal premium SaaS website design.
