/* =========================================================================
   NIZU Chat — iOS "Liquid Glass" (2026) skin
   -------------------------------------------------------------------------
   A non-destructive restyle of the Team Messenger widget (.rise-chat-wrapper)
   into a translucent, frosted-glass mobile-app aesthetic. Loaded AFTER
   app.all.css / custom-style.css so it overrides the base chat styles; it
   changes visuals only and keeps every existing class / JS hook intact.

   Structure it themes (unchanged markup):
     .rise-chat-wrapper  → floating glass panel
       .rise-chat-header → frosted top bar + control chips
       .rise-chat-body   → scrollable message area
         .chat-row.chat-me / .chat-other > .chat-msg  → glass bubbles
       .rise-chat-footer → floating glass composer (textarea + send/attach)
     .init-chat-icon     → glass launcher bubble
   ========================================================================= */
