/* HOUSBE Deal Room — compact chat (2026-11-11)
   Rows rendered by js/hb-compact-chat.js. Spec: HOUSBE_Compact_Chat_Developer_Specification
   ("selected design 1"). New class names (hbc-*) so none of the old glass-card
   rules in assets/css/deal-room-shell.css (.msg-row / .bubble / .sender-line)
   reach these rows. Where a row reuses an old hook class for its handler
   (.msg-viewer-summary, .editMsgVisibility, .askConcierge) the old styling is
   overridden here with a more specific selector. */
