/* Connections > Always-on assistant.

   Operator, 30 Sep: "this entire assistant page is too ugly, it needs to be
   simpler, more elegant." What it was: an accent-tinted system card, a row of
   engine cards, a surfaces grid and a second explainer bar at the bottom that
   repeated the first one.

   What it is: one calm hero that says what the assistant is, with its state
   and its model on the same line, and then Channels — cards in the connector
   cards' own grammar, because a channel is a connection and the board already
   has a card for that (they share .assistant-channel / .connection-card in
   foundation.css, so the shell, the grid and the logo are literally the same
   rules). */
