Seven-Layer Reference Architecture

Landscape illustration in a consistent series style: flat-vector editorial tech illustration with subtle isometric depth; clean geometric shapes, crisp edges, generous negative space. Background: deep navy gradient #020617 to #0F172A with a faint technical grid; the image carries its own background. Neon accent palette with a soft glow: cyan #06B6D4, violet #A855F7, blue #3B82F6, green #22C55E, orange #F97316. One clear central subject with at least 8 percent safe margin on every side. People appear only as simple abstract figures or silhouettes, never realistic faces. ABSOLUTELY NO text, letters, numbers, labels, logos, brand marks, watermarks, or readable UI anywhere. Code and documents are shown as abstract lines and blocks only. Scene: Seven thin translucent rectangular layers float in an exploded isometric stack with even gaps between them. The bottom layer holds a small tray of blank ticket cards; the next a state-machine diagram of rounded nodes and arrows; the middle layer a small robot agent at a workbench; above it an open book with connector plugs; then a shield; then a test tube with a check mark; and the top layer is a soft dome with a heartbeat line. A single vertical beam of light runs through all seven layers. Lead colors cyan #06B6D4 and blue #3B82F6. No text of any kind.
