/* ============================================================
   OKY — Assistant (AI chat) page (redesign)
   Pixel mapping of the approved Figma "Assistant" frame onto the
   panel_ui SPA. Reuses the dashboard redesign palette (--d-*
   tokens + Montserrat/Inter from dashboard.css / vars.css); adds
   only the screen-specific classes below, all `pg-asst-` prefixed
   so nothing here leaks into other views.

   The chat shell is a single white card: a scrollable message log
   on top and a docked input bar at the bottom. Assistant turns use
   an "OK" avatar + light bubble; user turns are right-aligned blue
   pills. The model/vendor behind the assistant is never named
   (hide-security-internals rule).
