- **Depends on:** `2026-10-26-zig-generics-and-numbers.md`, which supplies duck-typed per-type-copy generics, no traits (enums plus duck-typed operator methods), native typed arrays, and `Int`/`Float` kept as i64/f64 with `Int` narrowed to Int at `extern fun` boundaries (no JS BigInt in the browser bridge). That plan runs first.

  **Goal:** Port `../kam_macroquad`, a 98k-line Rust/macroquad remake of Knights and Merchants that already runs in the browser via wasm, to Plum as a **simplified** game. There is no mission scripting (rhai) and the rules are simpler, but animations and sounds stay identical. It runs in the browser first.

  **Architecture:** the Rust/macroquad host keeps asset decoding, audio and the window, compiled to wasm32 for the web or native. The Plum wasm-gc module owns game state, rules, pathfinding, AI, animation timing and per-frame draw calls. On the web the two modules talk through JS (miniquad plugin), and natively through wasmtime.
