/* ============================================================
   SRT ENGINEERING COPILOT — Chat Widget Stylesheet
   Phase CHAT-UX-1
   ------------------------------------------------------------
   Design tokens reuse the site's existing brand colors, already
   hardcoded across chatbot.js and styles.css:
     Navy   #13294B   Orange #F07C1D
     Fog    #F7F9FB   Border #E3E8ED   Muted #8496A3
   This file introduces no new brand colors — only structure,
   spacing, typography and (new) dark-mode variants of the same
   palette.
