To apply different styling for various parts of an app, what is the recommended setting?

The recommended setting to apply different styling for various parts of an app is to use the option that applies to the app and all modules. This approach ensures a consistent design language across the entire application, allowing for customizable styles at both the app level and within individual modules. By using this setting, any specific design choices made at the app level will automatically propagate to all modules, simplifying management and ensuring coherence in user experience.

This is particularly important when working on larger applications comprised of multiple modules, as it helps maintain brand identity and functionality without the need to replicate styling rules in each module separately. It enhances the developer's ability to implement design changes efficiently, as adjustments made at the global level are automatically reflected throughout the system.

Other options may limit the scope of styling, either to individual modules or the app without incorporation of all modules, which could lead to inconsistencies and increased maintenance efforts. Global style settings, while also crucial, may not directly imply the propagation across all modules unless specifically configured to do so, lacking clarity in the context of styling application across an entire app structure.
