## Description

This project provides a methodology for organizing, scoping, and naming styles to ensure maintainable and scalable stylesheets in large web applications. It functions as a structured approach to managing component-based styles, preventing global namespace collisions and simplifying long-term codebase maintenance through a set of established design principles.

The architecture relies on strict namespace-based encapsulation, where all class names are prefixed with unique component identifiers to ensure visual isolation between modules. It enforces a class-only selector strategy to avoid the maintenance risks associated with element or identifier selectors, while utilizing child-combinator selectors to restrict style application to direct descendants and prevent unintended visual leakage into nested components.

The methodology promotes modular development by grouping related assets, such as styles, scripts, and tests, into single directories for each component. It also includes patterns for wrapping third-party styles within local definitions, allowing for the integration of external design systems while maintaining control over local naming conventions and implementation details. A strict one-to-one mapping between component namespaces and source files is enforced to ensure predictable discovery and simplify refactoring as the project grows.
