-- `moth` - Higher-level game framework that simplifies Prosperon usage
-  - Handles window creation, game loop, and event dispatching
-  - Provides simple configuration via config.js 
-  - Auto-initializes systems like rendering and input
-  - Manages camera, resolution, and FPS automatically

 ### Rendering
 - `draw2d` - 2D drawing primitives
 - `render` - Low-level rendering operations

-### Actor Object Transparency
-Actor objects must be completely opaque black boxes that work identically regardless of transport:
-
-```javascript
-// Actor objects work transparently for:
-// - Same-process communication (fastest - uses mailbox)
-// - Inter-process communication (uses mailbox) 
-// - Network communication (uses ENet)
-
-// The actor shouldn't know or care about the transport mechanism
-send(opponent, {type: 'move', from: [0,0], to: [1,1]});
-```
 
 **Key Implementation Details:**
 - `actor_send()` in `scripts/core/engine.js` handles routing based on available actor data
