16 d2 diagrams covering architecture (IPC bridge, system tiers,
testability, audio bus), data flow (perception, dialogue, eavesdrop
pipelines), entity (knowledge graph, NPC generation, dialogue tags),
state (simulation tiers, movement stances, knowledge confidence), and
UI (HUD layout, interaction flow, fog layers). PNG output for universal
viewer compatibility. Removes test SVG from font debugging.
