PIN registration
There is no public open signup. Every account consumes exactly one activation PIN.
Flow
Enter the PIN → the app shows a safe sponsor preview (alias / member code only).
Create email, alias, and password → accept terms → account is created and the PIN is consumed atomically.
Verify email before full activation.
Rules
A PIN cannot register two accounts. Concurrent attempts will fail for the loser.
PIN purchase never creates binary volume or commissions. Only configured product revenue can.
