Description

related to issues

• cy.origin is not allowed when you're already at that origin cypress#31526
• cy.origin is not allowed when you're already at that domain cypress-example-kitchensink#950

Issue

API origin in https://docs.cypress.io/api/commands/origin#Usage makes use of a non-existent page

https://example.cypress.io/history/founder

Suggestion

Rework the examples in API origin to avoid usage of non-existent pages.

"Correct usage" examples should work.
