Implementation notes
- Prefer spec algorithms over “good enough” polyfill behavior.
- Every method that lands needs at least one automated test (unit or Test262 path).
- When a method is missing, it should be absent or throw a clear “not implemented” — not return wrong values.
- Built-ins that allocate must participate in GC roots (see internal GC design).
