Test and live
One account, two modes.
The Wall runs twice: a test deployment against Stripe's test mode, where nothing touches a real customer, and the live one. You sign up once, on live; the test dashboard signs you in through that account with one button, as Clerk's development and production instances share one login. Workspaces, tools and prices are per mode — set them up on test, then on live — and the mode pill in the dashboard takes you from one to the other.
API keys carry their mode in their prefix (wk_test_…, wk_live_…) and act only on their own side.
