Feature Prioritizer (RICE)

Score each PRD feature using RICE:

- Reach: How many users affected?
- Impact: How much improvement? (3=massive, 2=high, 1=medium, 0.5=low)
- Confidence: How sure are we? (100%, 80%, 50%)
- Effort: Person-weeks to build

RICE = (Reach × Impact × Confidence) / Effort

Rank features by score.
