/* ============================================================================
   MUN Suite — shared design system
   An institutional, UN-document-inspired theme: deep navy, a restrained
   brass/gold accent used sparingly for primary actions and emphasis, a
   serif wordmark/display face paired with a clean sans for dense UI, and a
   single reusable "globe" emblem as the brand mark throughout.
   Built entirely as CSS variables so a conference can restyle
   (theme_color from the conferences table) without touching structure —
   and every class name below is referenced from the page scripts, so keep
   the names stable even if you retune the values.
