  House style for the oTree admin (navy, Nunito, white cards on a navy band,
  "oTree × LISS" in the top menu).
  Loaded by _templates/otree/BaseAdminAll.html after oTree's own styles, so
  only admin pages use it. Participant pages use styles.css.
  oTree's admin is built on Bootstrap 5.0.1; the rules below restyle its classes.
