Educational technical book figure, 16:9 landscape, flat vector with soft 3D depth, deep night navy background, cyan and soft violet accents, warm off-white panels, high contrast, generous margins.

Center: one solid rounded cube labeled exact text "ENGINE" with a soft cyan edge glow.
Exactly three surface cards around the engine, connected by thin spokes — no fourth card:
top-left card exact text "TUI" with a minimal terminal window silhouette,
top-right card exact text "Headless" with a script pipe and exit-code badge,
bottom card exact text "ACP" with a simple socket / IDE outline (generic, no brand marks).
A thin ring under the engine with exact text "same config" and exact text "same permissions".

Exact labels only, spell exactly: "ENGINE", "TUI", "Headless", "ACP", "same config", "same permissions".
No logos, no watermarks, no artifact letters, no extra surfaces, no meta notes. Architectural clarity, calm practice-book style.
