tsconfig.engine.json

// #15: engine-only tsconfig — drops `DOM` lib + `vite/client` types so a
// browser global inside an engine kernel (chaos, density, calibration, etc.)
// becomes a compile error. The seam ("single engine, two consumers") was
// previously enforced by grep only; this catches violations at typecheck.
//
// Strategy: explicit kernel WHITELIST (the canonical compute path + data
// model + serialization). Files NOT listed below are either FE/BE host
// layers (DOM, navigator, requestAnimationFrame, `import.meta.env`, etc.)
// or middle-tier shims that transitively import host code. They typecheck
// in the base tsconfig.json which keeps DOM + vite/client.
//
// Ambient `*.wgsl?raw` module declaration is shared via src/wgsl-modules.d.ts.

    // now carries them explicitly.
