// We show here how slots can be used to create generic components.
// In this example, the Card component is basically only a container. It is not
// aware of its content. It just knows where it should be (with t-slot).
// The parent component define the content with t-set-slot.
//
// Note that the t-on-click event, defined in the Root template, is executed in
// the context of the Root component, even though it is inside the Card component
