// null0 - AssemblyScript bindings for the null0 fantasy console
//
// This module provides AssemblyScript bindings for the null0 fantasy console API.
// It allows you to create games that compile to WebAssembly and run in the null0 runtime.
//
// Usage:
//
// Create your cart by implementing the required callbacks:
//
// ```typescript
// import { clear, draw_circle, BLACK, RED } from "./null0";
//
// export function load(): void {
//     // Initialize your game
// }
//
// export function update(): void {
//     // Update game logic (60 FPS)
//     clear(BLACK);
//     draw_circle(100, 100, 50, RED);
// }
// ```
