in

Push a nested element scope so following steps resolve inside a labeled region. Separate from iframe scope.

Syntax

When I in "<region>"
When I in ".."
When I in "page"

Form	Effect
`in "<region>"`	Push: find a unique visible container under the current root, then nest
`in ".."`	Pop one level — fails if already at root
`in "page"`	Clear the entire element stack (iframe `scope` unchanged)

When I in "products"
When I in "Laptop"
When I fill "note" with "gift"
When I click on "Delete"
When I in ".."
When I in "page"

One-shot click inside a container without changing the stack:

When I click on "Delete" in "Laptop"

Containers resolve by id / aria-label / data-testid / container strategies.
Nested in "outer" then in "inner" narrows under the current root.
Cleared at each Scenario: / Feature: boundary.
Element in does not affect bare should see text search the way iframe scope does.
