import * as React from "react";

/**
 * Runs `fn` once `ms` has elapsed without any value in `deps` changing. The
 * timer is (re)started on mount and whenever `ms` or a value in `deps` changes.
 *
 * Uses the latest-ref pattern instead of `useEffectEvent`: effect events don't
 * update past the first render inside `React.memo`/`React.forwardRef` wrapped
 * components (React 19.2), which would silently break callers.
