tests/UI remains the active validation entry point. new_editor is not a test entry point.
Shared infrastructure belongs in shared/. Do not duplicate host plumbing per scenario unless the scenario is intentionally a custom host.
One scenario maps to one executable.

Build:

cmake --build build --config Debug --target editor_ui_integration_tests

Screenshot output:

Shared Editor integration hosts write screenshots only under the active CMake build directory.
The output root is the executable directory: .../Debug/captures/<scenario>/.
Example output: <build>/tests/UI/Editor/integration/shell/object_field_basic/Debug/captures/object_field_basic/latest.png
History output: <build>/tests/UI/Editor/integration/shell/object_field_basic/Debug/captures/object_field_basic/history/<timestamp>_<index>_<reason>.png
No new screenshot output is allowed under source-tree tests/UI/.../captures/.
