Role Assignment Interface - Copy this Html, Tailwind Component to your project

Design a UI for assigning roles to a device in a media streaming network. The interface should feature a clear with greeting and text to "select option". For the device, include a dropdown or selection box where the user can choose roles like 'Video Control Master,' 'Video Display Slave,' etc. At the bottom, provide a 'Confirm' button to save the assignments and an 'Shutdown' option for changes. Use a clean, modern style with clear labels and intuitive positioning for the role assignment section. Highlight the selected role with a light colored background.
