   🎨 GLOBAL THEME COLOR
   Change the single --theme value below and the whole page re-colors
   (background glows, brand pill, avatar ring, buttons, focus states).
   Every accent shade is derived from it with color-mix(), so nothing
   else needs editing. Remember to sync <meta name="theme-color"> in
   index.html if you want the browser chrome to match.
   Supported: Chrome/Edge 111+, Firefox 113+, Safari 16.2+
