A retro flat-color 3D isometric editorial illustration on a pure white background.

Scene: “Threat Modeling — Chess Board vs Chess Pieces”. A 40-year-old male security engineer (dolfly: short graying hair, glasses, casual retro-blue shirt) stands at a split view. His LEFT hand rests on a glowing holographic chess board showing system topology — servers connected by lines, data flow arrows, attack surface marked in coral red. His RIGHT hand points at a isolated chess piece (a glowing blue knight) — representing AI’s code-level view that only sees individual pieces, not the whole game.

The chess board dominates the left side with interconnected nodes. The single isolated piece sits on the right. The engineer stands in the center, bridging both worlds — the human who sees the full picture.

Style: 3-5 vintage colors from olive green, mustard yellow, retro blue, coral red, warm gray. Flat blocks, soft contact shadows, slight volume. 16:9 horizontal. Pure white background.

NO realistic humans, no backgrounds — pure white to all edges. Subject 55-65% of frame.
