Two follow-ups to the Nostr-native newsletter (skipped auto-DM by design — too spammy/fragile for now; the bell mailbox already covers the inbox feel). Subscriber count (social proof): - useNewsletterSubscriberCount tallies public NIP-78 subscription markers (deduped per author, counting current "true" state). - Shown under the subscribe CTA as "Join N+ skaters getting the drops", hidden until it's meaningful (>=3) and rounded once it grows. Archive backfill (consistency without losing the rich page): - lib/newsletterArticle.ts converts a static NEWSLETTER_ISSUES entry into a NIP-23 (kind 30023) article — structured sections rendered to Markdown, stable slug `issue-N`, published_at from the issue date. - NewsletterBackfillPanel (admin-only) diffs the static archive against what's already on-relay and publishes only the missing issues; safe to re-run, reports partial failures. The rich static page rendering is untouched. Co-authored-by: shakespeare.diy <assistant@shakespeare.diy>
