/* ═══════════════════════════════════════════════════
   MR. CHATBOT — DEFAULT WIDGET STYLING  (business-agnostic)
   ---------------------------------------------------
   The original project shipped with NO stylesheet — the
   chat panel's look lived entirely in each client site's
   own CSS, targeting the old .guru-* class names. This
   file makes the engine self-contained: drop the whole
   MR-COOL folder into a site, link this stylesheet, and
   the widget already looks clean on both desktop and
   mobile with zero extra CSS required.

   INTEGRATING INTO A SITE THAT ALREADY HAS ITS OWN CHAT
   STYLES (targeting the old .guru-* classes): either link
   this file instead and delete the old rules, or update
   your existing selectors from .guru-* to .mrchat-* (a
   simple find/replace) — see README.md.

   Colours are CSS variables so a brand colour swap for a
   new business takes one edit, right here at the top.
