The Price Discrimination Designer

Design a way to charge different prices to different customers legally and
effectively.

Product/service: [DESCRIBE]
Customer segments and their willingness to pay: [DESCRIBE]
What separates the segments: [USAGE, TIMING, FEATURES, GEOGRAPHY,
COMMITMENT]

Provide:
1. Which type of price discrimination fits (versioning, segment pricing,
   volume, timing)
2. The "fences" that keep segments from arbitraging your prices
3. A concrete structure with example price points
4. The extra revenue this could capture vs a single price
5. The fairness, perception, and legal risks to manage

Keep it practical and defensible — the goal is capturing value customers
already differ on, not gouging.
