Code Review

This pull request updates the Colors plugin to version 1.3.0, introducing a significant refactor of the user interface and color management logic. Key changes include the addition of new slider components for RGB and HSL color spaces, a centralized configuration store for color formatting preferences, and several new UI utility components such as Select, ToggleButton, and Space. The main page layout has been reorganized into a responsive grid. Feedback focuses on improving visual consistency and code quality, specifically recommending the alignment of transition effects on the Card component, fixing a missing CSS variable in the Slider component, and cleaning up unused logic in the ToggleButton component to ensure it correctly respects its properties.
