Plans and credits

• Choosing a plan: how the free trial, credit packs and subscriptions differ, and how to pick one.
• How credits work: what moves the price of a generation, where you see it first, and how long credits stay usable.
• Cancel a subscription: the steps in Settings, what you keep until your paid date, and when money can come back.
