Each step is the tooltip the visitor sees, a one-line description of the screen, and what that screen is in Everflow. Generated from `screens_json` — not a second CMS.

## Step 1 · Add Rule · Behavior · the condition

- **Screen:** Add Rule · Behavior · the condition
- **In Everflow:** An Everflow product screen in this interactive walkthrough.
- **Tooltip:** This toggle is the fork in the road. Leave it on Metric to count what the customer did. Switch to Custom Data Point only to compare a value you sent. The email that identifies the person never appears here.
