/**
 * WARNING:
 *
 * Any changes made to the types of the Redux store could potentially require a migration.
 *
 * If you're making a change that alters the structure or types of the Redux state,
 * consider whether existing state stored in users' browsers will still be compatible
 * with the new types.
 *
 * If compatibility could be broken, you may need to create a migration
 * function that can convert the existing state into a format that's compatible with
 * the new types, or otherwise adjust the user's persisted state in some way
 * to prevent undesirable behavior.
 *
 * See state/README.md for more information on creating a migration.
 *
 * If no migration is needed, just update the expected types here to fix the typecheck.
