/* ==========================================================================
   Ziidoo — professional services design system
   --------------------------------------------------------------------------
   Principles
   1. White page, near-black type, hairline rules. Structure comes from space
      and rules, not from boxes and shadows.
   2. Brand green (#83BD32, sampled from the logo) is an accent, never a
      surface. It appears on the wordmark dot, link arrows, and index numerals.
   3. Display type is large and light. Weight is earned by size, not by 800.
   4. One accent, one neutral ramp, one type family. No gradients, no glows.
