To achieve the desired outcome, I’ve opted for an approach that follows this pattern:

— Create a service with a `mediaQuery()` method, which returns an RxJS Observable containing information on whether a specific breakpoint is matched or not.

— Create a property inside the component class (in the example we will call it `isMobile`, since we have only one breakpoint) and bind it the the `mediaQuery()` method previously crafted, but also converting the Observable to a signal.

— Utilize the `NgClass` directive to dynamically apply a class based on the value of the `isMobile` property.
