## Description

Suit is a CSS component architecture framework and methodology designed for organizing styles using predictable naming conventions for components, descendants, and visual variations. It serves as a design system styling framework that maps application states and design variations to modular CSS rules.

The system utilizes namespace-based CSS scoping to isolate component styles and prevent unintended side effects in global stylesheets. It also functions as a utility-first toolkit, providing a system for applying single-purpose layout and spacing rules to reduce code duplication.

The methodology covers the management of frontend design systems through modular UI styling and standardized component naming. It incorporates patterns for structuring stylesheets into components and modifiers to ensure styles remain scalable as user interfaces grow.
