CSS Author Skill

This skill provides patterns for organizing CSS in modern, maintainable ways without build tools. We leverage native CSS features: @import for modularization, @layer for cascade control, and nesting for readability.

Philosophy

CSS should be:

1. Native - No preprocessors or build steps required
2. Modular - Organized by scope and purpose
3. Predictable - Cascade layers eliminate specificity wars
4. Semantic - Target elements, not class soup
