GLOBAL STYLE (apply to every figure unless overridden):
- Genre: clean educational technical illustration for a professional practice book about agentic coding tools; flat vector + soft 3D depth; not photorealistic clutter.
- Palette: deep night navy (#0B1B2B), cyan (#2EC4FF), soft violet (#8B7CFF), warm off-white panels, muted slate grays; subtle glass/glow accents.
- Typography in image: minimal English labels only (2–6 words max per label); no paragraphs; no fake code walls.
- No brand logos (no xAI, no GitHub, no VS Code marks); only generic terminal / editor / browser chrome.
- Composition: clear focal hierarchy, generous margins for print crop, high contrast suitable for grayscale photocopy fallback.
- Negative: no stock-photo faces, no cartoon mascots, no neon cyberpunk overload, no watermarks, no UI screenshot photorealism.

QUALITY GUARDRAILS (mandatory):
- Every visible word must be real English, correctly spelled; never invent gibberish filenames or pseudo-code.
- Never render meta instructions, style notes, palette names, or prompt fragments as labels (e.g. no “night navy metallic”, “detail crystals”).
- Prefer real short path examples when needed: auth.js, routes.ts, store.py, tests/api/**, AGENTS.md, config.toml — not random letter salad.
- No versioned model product names; use generic “model” or “coding model” if needed.
- Max ~12 short labels total; if cluttered, drop labels rather than inventing filler text.
- This book title is “Grok Build Practice Guide” — never “The Claude Code Harness” or sister-book titles.
