Reframe A Campaign That Has Lost Momentum

The table used to buzz after every session and now people check their phones during downtime scenes. This reframes the flatness as a fixable stage rather than a failure, works out whether it is a lull or a genuine dead end, and suggests one concrete change for next time, or a fair way to wrap up.

<context>
Your {SYSTEM_NAME} campaign has been running for {TIME_PERIOD} and sessions have started feeling flat, with players less engaged than at the start.
</context>

<task>
**Reframe the situation and suggest a way forward:**
1. Common causes of mid-campaign flatness that are not about the game master failing (scheduling gaps, plot sprawl, a resolved main goal with nothing yet to replace it)
2. Distinguish between a genuine dead end and a natural lull that a change of pace could fix
3. Suggest one concrete change for the next session: a shorter arc, a new stake, or a change of scene
4. One honest note on when it is fair to just end the campaign well rather than force it on
