Preconditions:
  1. Start a trial project and follow the onboarding flow up to the subscriptions: https://onboarding.ucraft.ai/subscriptions
  2. Make sure you choose a subscription other than 'Free'
Observations:
  1. Though 'Checkout' button is active, it is not super-clear that the user can checkout without attaching a credit card, if plan is not 'free', because it shows e.g. $216 in total to pay and there are no messages guiding the user the they can checkout for free without attaching a card, how long their trial will take, when will we need them to attach a card, etc.
So we may need to add texts and descriptions here to guide the user.
  1. There is no 'back' button, so it is not clear that the user can go back to change the plan or click on the 'Plan' to change the plan there, if they have changed their mind about the plan.
Back button might be needed, or arrows to show the stepper.
