// A topic feed (#gardenstr) goes back as far as the relays remember: the
// big relays prune, so topics also ask archive-keeping ones, and a page
// whose posts were all filtered out (replies, muted, spam) is not the end.
// Before: ~5 posts, then "You're all caught up".
//
// Run: bun tools/topic-depth-test.js
