How to post a thread on X, Threads, Bluesky or Mastodon

// Paragraphs become parts. Check each part against the platform's limit.
const draft = `BuzzTake posts threads now.

Send the first post in text and the rest in thread.

One action, one charge.`;

if (tooLong.length > 0) throw new Error(`${tooLong.length} part(s) over ${LIMIT} characters`);
if (thread.length > 25) throw new Error("A thread takes at most 25 more parts.");
