nx_gassim_wasm_vm_gate.nx source

1// nx_gassim_wasm_vm_gate.nx -- RUN (not just compile) the browser gas-sim wasm in our OWN sovereign WASM VM 2// (nx_wasm_vm), no browser/node/wasmtime. Loads web_assets/nx_gassim.wasm, instantiates, calls init()/tick(0)/ 3// render() (the integer hard-disk physics + rasterizer execute), reads step counter + framebuffer back out, and 4// confirms determinism. Closes the compile-vs-execute gap.
