/*
  Husam's five colours on the Django admin (SPEC §3, §4.6):
    #192D2B and #142423, two near-black greens; #CDC9BE and #BDBBAE, two greiges;
    #D49F59, a gold. The other values are tints and shades of them, for surfaces the
    five can't cover with enough contrast. Every text-and-background pair reaches 4.5
    to 1 in both themes; tests/test_m2_daily_tasks.py checks each one.

  The admin's own themes: light by default, dark when the system asks for it unless
  the theme toggle says light, and dark when the toggle says dark.
