/* =====================================================
   Messenger (Messages module) — modern two-pane layout
   Left pane  : conversation list (search, tabs, threads)
   Right pane : conversation (messages + composer)
   >=1024px   : panes sit side by side inside one frame.
   <1024px    : one pane visible; selecting a thread slides
                the chat pane over the list (slide-over).
   NOTE: Tailwind Play CDN injects its generated stylesheet after this file,
   so its .hidden / md:flex etc. win cascade ties against the display rules
   below — no !important needed (one that would also break responsive
   un-hides like `hidden md:flex` inside the messenger).
