   ADVISORY BOARD — style.css
   
   Advisor colors are NOT hardcoded here.
   Each advisor element receives --advisor-color as an inline
   CSS custom property set by ui.js at render time.
   Generic rules read var(--advisor-color) for borders, dots,
   avatars etc. Adding a new advisor requires zero CSS changes.
