<!--
  Why: the Web control surface (DOC-20 §6 Phase 2, ONB-3) — a browser chat page
       that drives managed sessions through the EXISTING action-capable chat
       endpoint. It embeds no session logic; it is a thin presentation layer over
       POST /api/v1/sessions/chat with `actions: true`.
  What: a single self-contained page (no build step, no external assets) that
       POSTs the operator's message to the chat-core endpoint, renders the SM
       `reply`, and surfaces the `actions_taken` audit trail. `conv_id` is echoed
       back and resent so the rolling SM context continues across turns.
  Test: served by `web_chat_page` (see web_routes.rs); the daemon route tests pin
       status + content-type + key markers in this body.
