# Page Routing Logic

The system always routes the user to the correct page:

* **Forward Routing**: If the current page is completed and valid, proceed to the next page.
* **Backward Routing**: If the prerequisites of the current page are not met, return to the previous page.
* **Skipping**: Some pages are automatically skipped depending on the user's state (for example: if there is only one delivery option, the selection page is skipped).
