How would you implement debounce for a search input using Streams?

This tests whether you understand Stream transformation and event throttling in reactive programming rather than just imperative async logic. A strong answer outlines a timer that resets on every input event and only emits the latest value after 300ms of silence, explicitly referencing debounceTime or DebounceStreamTransformer. It should distinguish debounce from throttle and explain why you want the last event, not the first. Red flag: describing manual Timer management inside a listener without leveraging Stream composition or transformers.
