   Birthe C. Reimers, PhD — Independent Ombuds Program Advisory
   Editorial design system.

   Restraint is the point: ivory and white grounds, deep navy for authority,
   charcoal body, warm-gray hairlines, a muted teal used only for eyebrows,
   small rules, and fine accents. Elegant serif headlines (Cormorant Garamond),
   quiet sans-serif body (Inter). Thin rules instead of boxes. No drop shadows,
   no card chrome, no loud color. Whitespace does the work.
