/* Chatbot v5 inbox (owner, 2026-10-28; docs/dev/2026-10-chatbot-v5-spec.md section 6).
   Desktop: customers | chat | Info, three columns. Under 1200px the Info panel slides over the chat; under 900px one
   column at a time (list, then chat, then Info full screen). Every text is at least 16px (owner's rule).
   The four "who is handling it" colours come from server/inbox_state.py: you (yellow), ai (violet), owner (blue),
   log (grey). Loaded after console.css, so the .ht-* rules it overrides stay in one place for the old Bot tab. */
