+## How the Code Is Organized
+
+The game uses a modular runtime split across 11 files in `js/`. Each module handles a specific domain:
+
+1. **Data layer** (`data.js`) — All game constants, building definitions, project specs
+2. **Core engine** (`engine.js`) — The tick loop, state transitions, event system
+3. **Rendering** (`render.js`) — DOM updates, UI state visualization
+4. **Gameplay systems** — `combat.js`, `strategy.js`, `dismantle.js`, `emergent-mechanics.js`
+5. **Support systems** — `sound.js`, `tutorial.js`, `utils.js`
+6. **Entry point** (`main.js`) — Bootstrap, event listeners, initialization
+
+`index.html` loads all modules in dependency order. No bundler required.

-### Potentially Unimported Files
+### Dead Code — Resolved (2026-04-15, Issue #192)
 
-The following files were added by recent PRs but may not be imported
-by the main game runtime (`js/main.js` → `js/engine.js`):
+The following files were confirmed dead code — never imported by any runtime module.
+They have been moved to `docs/reference/` as prototype reference code.

-**Action:** Check if `js/main.js` or `js/engine.js` imports from `game/` or `scripts/`.
-If not, these files are dead code and should either be:
-1. Imported and wired into the game loop, or
