   static/shared/vivian-theme.css — Vivian Unified Design System

   One theme for ALL Vivian websites. Every landing page, dashboard, and
   admin panel shares these CSS variables and base styles.

   Drop into any page:
     <link rel="stylesheet" href="/static/shared/vivian-theme.css">

   The shared navbar (vivian-navbar.css) handles the top bar.
   This file handles everything else — colors, typography, cards, buttons,
   forms, and the cross-linking footer.
