// Notifications: a custom-emoji reaction (NIP-30, ":peepoClap:" with an
// emoji tag) reads "reacted" plus its picture — it showed the bare
// :peepoClap: text, because the row kept the content and not the tag.
// A row saved before that is healed when the relay hands the reaction again.
// Run: bun tools/notif-custom-emoji-test.js
