      # Redundant today: `npm ci` above runs `prepare`, which builds `webpack:all`, and its
      # ts-loader already typechecks this same tsconfig program - so a type error fails that
      # step first. Kept explicit so the guarantee does not rest on that incidental side

      # it, and nothing would tell us.
