// Hands-On tutorial — Movie Dashboard custom component (C# side).
// Implements IRenderableComponentV2 (the modern contract) and
// IComponentTypeProvider (to expose a stable type-key for the React shell).
//
// Wiring:
//   MIB3UX_COMPONENTS.ASSEMBLY_NAME = "Acme.Mib.HandsOn"
//   MIB3UX_COMPONENTS.CLASS_NAME    = "Acme.Mib.HandsOn.MovieDashboardComponent"
// The React widget under "acme_movie_dashboard" will render this.
