# CSS Design System Rules

## Documentation (READ FIRST)
- **Quick Start**: `docs/ONBOARDING_CSS.md` (5 min read)
- **Complete Patterns**: `docs/CSS_PATTERNS.md` (cards, forms, buttons, tables, etc.)
- **Design Tokens**: `docs/DESIGN_TOKENS.md` (colors, spacing, typography variables)

## Core Principles
- Use CSS variables from design tokens, NEVER hardcoded values
- Check `CSS_PATTERNS.md` BEFORE writing any CSS
- Import shared styles from `shared/frontend/styles/`

## Shared Styles to Import
- Login: `@import 'shared/frontend/styles/login.css'`
- Header: `@import 'shared/frontend/styles/layout/header.css'`
- Navigation: `@import 'shared/frontend/styles/layout/navigation.css'`

## NEVER
- Use `:deep()` for PrimeVue overrides (use `vendor/` files)
- Duplicate patterns that exist in CSS_PATTERNS.md
- Use hardcoded colors like `#2563eb` (use `var(--color-primary)`)
- Create scoped CSS for patterns that already exist in shared files
