Implementing design tokens and theming with CSS-first configuration
Building responsive and accessible components
Standardizing UI patterns across a codebase
Migrating from Tailwind v3 to v4
Setting up dark mode with native CSS features
Key v4 Changes

Core Concepts
1. Design Token Hierarchy Brand Tokens (abstract)
└── Semantic Tokens (purpose)
└── Component Tokens (specific)
Example:
oklch(45% 0.2 260) → --color-primary → bg-primary
2. Component Architecture Base styles → Variants → Sizes → States → Overrides
