- CreationWizard: add sys.skills to the loader effect's deps (stable singleton).
- Extract NotFound to src/app/NotFound.tsx so router.tsx no longer trips
react-refresh/only-export-components.
Branch is now warning-clean (the 3 remaining eslint errors are pre-existing on master,
in files this branch does not touch).
