Create a premium high-resolution book cover BACKGROUND ART (typography will be added later in layout). Portrait aspect ratio 2:3 (ideal export 2400×3600 px or higher). Professional German technical non-fiction about agentic coding tools — calm, precise, demystifying; NOT marketing hype, NOT cyberpunk poster.

SUBJECT / CONCEPT:
"The Grok Build harness — a precision workbench for an AI coding agent, not magic."
Visual metaphor: elegant control room / developer workbench that steers a language model. The model proposes; the harness gates, tools, and loops.

COMPOSITION (strict zones for later typography):
- Upper third (~0–35% height): mostly clean deep negative space (dark navy gradient) for title overlay later. Very few sparse floating elements only at the edges; center-upper remains uncluttered and dark.
- Middle band (~30–65%): hero focal composition — a refined geometric “harness core”: layered translucent panels stacked like a precision instrument.
  Include these abstract modules (icons, not screenshots):
  1) Terminal TUI shell with single glowing cursor line
  2) Permission gate as a small three-state traffic-light node (allow / deny / ask) — subtle, elegant, not cartoonish
  3) Circular tool-loop ring (proposal → gate → execute → result returns)
  4) Thin scroll / document slab suggesting AGENTS.md / config — NO readable long text
  5) Soft satellite surfaces orbiting the core (tiny terminal TUI, headless pipe, ACP socket) connected by thin cyan spokes — “one engine, three surfaces”
- Lower third (~60–100%): grounded technical terrain — subtle circuit / architecture lattice fading into darkness; soft cyan and violet light paths; generous quiet margins for author line / year later.

STYLE:
- Hybrid of premium editorial 3D glassmorphism + clean flat vector clarity
- Depth via soft volumetric light, gentle bloom, restrained reflections
- Material feel: dark frosted glass, brushed metal edges, holographic edge light — sophisticated tech non-fiction, O'Reilly-adjacent seriousness without their animal illustration
- Lighting: cool cyan rim light from lower-left/right, soft violet ambient fill top-left; no harsh neon floods
- Photoreal faces: none. Human figures: none (or at most a tiny abstract geometric operator silhouette without face, optional, very small)

COLOR PALETTE (strict):
- Base: deep night navy #0B1B2B, indigo #1A365D
- Accents: cyan #2EC4FF, soft teal #2A9D8F
- Secondary: soft violet #8B7CFF
- Neutrals: slate #4A5568, warm off-white #F4F7F6 for tiny highlights only
- Avoid: pure black voids that crush detail; rainbow gradients; red alert overload

TYPOGRAPHY IN IMAGE:
- NONE. Zero letters, zero words, zero fake titles, zero brand names, zero monospaced code paragraphs.
- Any “labels” must be pure iconography / abstract glyphs only.

NEGATIVE CONSTRAINTS:
- No xAI logo, no Grok brand mark, no VS Code / JetBrains / GitHub logos
- No Anthropic/Claude references, no robot mascot, no magic clichés, no watermark, no dense fake code walls
