/* ─── Home (chat) page summary block ───────────────────────────────────────
   Embedded BELOW the chat example cards on the new-chat landing. Visually
   demoted from the main feed (smaller cards, denser spacing) so it doesn't
   compete with the chat input.

   No max-width / horizontal padding — we want this block to align exactly
   with .chat-examples-wrap above. The example wrapper sets its own width
   from the chat layout container; if we constrain max-width here, our
   block reads as slightly narrower than the examples and the visual
   alignment breaks.
