/**
 * Sync state to local storage so that it persists through a page refresh. Usage is
 * similar to useState except we pass in a storage key so that we can default
 * to that value on page load instead of the specified initial value.
 *
 * Since the storage API isn't available in server-rendering environments, we
 * return null during SSR and hydration.
 *
 * @param key - localStorage key. If null, persistence is disabled and
 *   the hook behaves like regular useState.
 * @param initializer - Initial value or function returning initial value
 * @returns A tuple of [value, setValue] where value is the current value
 *   from localStorage (or the initial value) and setValue updates it
