   Used by /events/ and /tour/. Moved here verbatim from /events/; the only
   addition is the button block at the bottom, scoped to the card so the card
   looks the same on pages whose own .btn is styled differently (/tour/).
   Relies on the page defining the usual palette vars (--surface, --cyan, …).
