URL-awareEach detected link reserves 23 weighted characters.

Weight map
Tokens marked ×2 use two weighted units under the public v3 ranges. Detected URLs are represented as URL · 23. This view is intentionally capped for speed on very long drafts.
Thread studio
Write a long post and choose Split into thread. The splitter preserves sentence/paragraph boundaries where possible and validates every segment with the same weighted counter.
