        - The data is formatted for readability
    - GET summary raw
      - Fetch Pi-hole Summary raw from API
        - The data is in raw format
  - export prebuilt React hooks for 'Summary' queries
    - useGetSummaryQuery
      - React hook for fetching Pi-hole Summary
    - useGetSummaryRawQuery
      - React hook for fetching Pi-hole Summary in raw format
