Prefer BUILD_MODE.md for the language of record. This page is a short pointer — older JS-transpile guidance was removed with the legacy emitters (LEGACY.md).
Browser / JS host
Build -target browser ships WASM + a thin DOM boot (scripts/luke_browser_loader.cjs). Luke owns layout/paint (Hanka → Argus); the page is a host surface, not the source of truth.
Errors
- Build:
ATTEMPT/GIVE UP/OTHERWISE, plus reactive isolation when using the reactive runtime. - Play VM: runtime errors surface through the SHOW path.
Modules
