island-boundary-slots.ts:9:12 - error SC1100: passing 'any'-typed values where '() => void' is expected (argument 1 of timers.setTimeout) is not supported yet

   8 | const cb: any = () => {};
   9 | setTimeout(cb, 1);
     |            ^~

  hint: validate with 'as <type>' first — the cast checks the dynamic value at runtime and throws on mismatch
