 ## Shared Test Fakes
 
-Both test projects share hand-rolled fakes from `tests/Shared/`. No mocking framework is used.
+Both test projects use hand-rolled fakes — no mocking framework is used. Cross-project fakes live in `tests/Shared/` (e.g., `TestDashboardClient`, `ModelTestHelpers`), while bUnit-specific fakes live in `tests/Aspire.Dashboard.Components.Tests/Shared/` (e.g., `TestLocalStorage`, `TestTimeProvider`).

 ## Test Conventions

+### DO: Use `[UseCulture("en-US")]` for Culture-Sensitive Component Tests
 
-All bUnit test classes should be decorated with `[UseCulture("en-US")]` for deterministic formatting:
+Apply `[UseCulture("en-US")]` to bUnit test classes that assert culture-sensitive formatting (for example, numbers or dates) so those tests run deterministically across environments:
