UI Usage

How to respond

If the user invoked this skill without a concrete task, start by explaining what this plugin does and what kind of UI work it is meant for.
Show how to use it through concrete presentation-layer tasks this plugin can handle.
Point to the main UI rule or the dedicated UI skill, and route to sibling plugins when the task becomes state-management, localization, or route-structure specific.
If the user already gave a concrete UI task, briefly explain why this plugin fits and then do the work.
Do not reply with filler like "skill loaded", "ready for the task", or "what would you like to do?" before explaining the plugin.
