Pay for capability, not content

Every lesson, every banked exercise, and real test feedback are free — forever, with a daily energy meter that refills on its own (reviews and remediation never cost energy). Pro removes the meter and the friction. Max adds the expensive, AI-native capabilities: unlimited tutoring, fresh generation made for you, and every capstone project with a senior-engineer review. No content is ever locked.
