* replace NavigationStack with ElementNavigationStack to allow the content to be rendered without a NavigationStack in a11y tests
* fix a11y tests
* update xcodeproject
* swiftformat fix
* use iOS 26.1 for CI
* use a wrapper to solve the issue for a11y tests
* ElementNavigationStack only uses the trick in DEBUG mode, and added a swiftlint rule to prevent the usage of NavigationStack
- Fixes a bug where gradients wouldn't use the latest tokens after first use.
- Makes the bloom aware of colour overrides (and discovers a bug with dark mode).
- Decouples HomeScreenCell from the HomeScreenViewModel.Context (so it can be previewed with colour overrides).
* Refactor the bloom into a modifier.
It currently depends on the home screen context but that will be removed in the future.
* Add an initial implementation of the new bloom using an image on the navigation item's appearance.
* Add a feature flag to control the new bloom.
