// FIXTURE: pattern-computed-reactive-map
// Verifies: .map() on a Reactive inside computed() is NOT transformed to mapWithPattern
//   computed(() => items.map((n) => n * 2)) → lift(({ items }) => items.map((n) => n * 2))({ items })
// Context: Inside the lift-applied computation, Reactive auto-unwraps to a plain array, so
//   .map() is a standard Array.prototype.map — it must remain untransformed.
//   This is a negative test for reactive method detection.
