Answer
Shared state must be managed in a common parent to keep child components synchronized.
Quick Answer
When two sibling components need to share state, move that state up to their common parent. The parent manages the state and passes it down as props. This keeps state in sync without global stores. It's the fundamental React pattern for sharing data — keep state as close to where it's needed as possible, but no lower.
