Implements a Vue directive (v-auth) for conditional rendering based on user permissions and roles. It encapsulates permission checking logic into a reusable, self-contained directive that can be applied to any element for button-level or view-level access control without tight coupling to specific components or stores.

A self-contained horizontal scrollable navigation container with navigation buttons to scroll overflow content. It demonstrates a reusable UI pattern for handling horizontal overflow in tabs or menus, encapsulating scroll logic, button controls, and touch/swipe support in an isolated component that depends only on basic Vue utilities.

Extends Element Plus's upload component with additional features like drag-and-drop support, file list management, progress tracking, and batch upload handling. It isolates complex upload logic into a reusable component that can be easily integrated into any form, demonstrating non-obvious skill in wrapping and enhancing third-party components while maintaining a clean API.

Provides a drawer-based panel for real-time theme customization (layout, colors, etc.) using CSS variables and dynamic style injection. It demonstrates a non-obvious pattern for runtime theme switching in a Vue 3 application, allowing users to personalize the UI without page reloads while maintaining type safety and encapsulation.
