According to Mendix best practices, where should $variables be stored?

Storing $variables in any partial with the name variable aligns with Mendix best practices because it promotes modularity and reusability across the application. By defining $variables in a specific partial dedicated to variables, developers ensure that these variables are organized in one location, making them easier to manage and update as needed. This approach also minimizes the risk of conflicts or inconsistencies that could arise from scattering variables throughout various parts of the application.

In a setup where $variables are stored in a dedicated partial, it enhances collaboration among team members, as everyone can quickly identify where the variables are defined and how they can be utilized. This leads to cleaner code, improved readability, and a more efficient workflow, particularly in larger projects where multiple stylesheets may be in play.

The other choices do not support these best practices as effectively. Storing variables only in global stylesheets does not provide the same level of organization or accessibility, as this method could lead to cluttering and difficulty in tracking variable usage. Using a separate configuration file may be appropriate for some settings but does not align with the goal of making variables easily accessible within the styling context. Keeping variables in the main stylesheet can also complicate management, especially if that stylesheet contains a variety of other styles that could
