What counts, and what doesn't
- Bluesky counts graphemes, so emoji and accented characters count as one each, friendlier than X's counting.
- You can trim how a link displays; the visible text is what counts against the limit.
- Threads (reply chains) are native, so 300 characters is a soft limit for a single beat of a longer idea.
