// Two shapes, chosen by whether a NIP-71 mirror was confirmed on relays:
//   mirror    -> quote card via `nostr:naddr1…`, NO bare thumbnail URL
//   no mirror -> bare thumbnail URL (described by the note's NIP-92 imeta)
//
// The "no bare thumbnail while quoting" rule is the one that matters visually:
// keeping both rendered the same image twice (once loose, once in the card).
