/* ============================================================
   CONTAINED CHAT — shared Browse Mode primitive (Task #424).
   A bordered on-ramp surface (NOT the real chat shell). Sits
   inside /home and /ai-ops as a way to hand a visitor's first
   prompt across to Ask mode. Chip click or composer submit calls
   BE.containedChat's onSubmit which, by default, writes the text to
   sessionStorage.be_pending_seed_prompt and navigates `/` (chat.js
   then dispatches it as the visitor's first user turn).
