+   :::warning Recommended slider setup
+   Using a slider is most effective when users can easily choose a value. If the range between the minimum and maximum values is too large (and/or the step is is too small), it may be difficult to select a specific value on the slider, leading to issues with the <MobileAppNameShort />.
