/* ============================================================
   Session 96 — Hộp thư chat (CTA0_0200) dialog + list layout fix
   (user screenshot 2026-09-02 09:45)
   Bug 1: .messages was display:grid with align-content:start, so a short
   conversation piled every bubble at the TOP of the tall conversation area
   leaving a huge void above the composer; the last staff bubble ("adf")
   looked detached / floating mid-window. Standard chat UX anchors the
   conversation to the BOTTOM. Fix: flex column + a ::before spacer whose
   margin-bottom:auto absorbs the free space (auto margins resolve BEFORE
   flex-grow, and collapse to 0 when content overflows, so scrolling from
   the top never breaks — unlike justify-content:flex-end / grid
   align-content:end which make top overflow unreachable).
   Bug 2: the admin inbox session list had no scroll region on desktop, so
   once rows exceeded the .split-chat height they were clipped by
   .split-chat{overflow:hidden} and unreachable. Fix: chat-list becomes a
   flex column (fixed head + scrollable #chat-session-list).
