Title: Broken Segmentation Plan (deliberately broken sample)

### Segment: Engaged Power Users
- Name: Engaged Power Users
- Rule: people who seem really into the brand and open most of our emails
- Size estimate: a few hundred, roughly
- Treatment: send them nice stuff

### Segment: Casual Browsers
- Name: Casual Browsers
- Rule: folks who just poke around the site sometimes
- Size estimate: not sure, maybe a lot
- Treatment: general newsletter

<!--
Deliberately broken checks:
1. Both "Rule" fields are prose, not machine-evaluable property logic (no
   comparison operators / AND / OR) — "prose-only rules fail" per the rubric.
2. Size estimates have no stated data source ("Source: ...").
3. No mutual-exclusivity/overlap declaration on either segment.
4. No RFM base layer anywhere (no R/F/M numeric boundaries).
5. No sunset/dead segment.
