#### Task 1.3: Component Styling Guidelines
**Status:** ⏸️ | **Est:** 1.5 hours

**File:** `docs/COMPONENT_STYLING.md`

**Content:**
```markdown
# Component Styling Guidelines

## When to Use Scoped Styles vs Global CSS

### ✅ Use Global CSS When:
- Pattern is used in 2+ components
- Styling follows established design system
- PrimeVue component customization
- Layout patterns
- Utility classes

### ✅ Use Scoped Styles When:
- Truly component-specific logic
- Complex component state styling
- Third-party library integration (Chart.js, etc.)
- One-off unique components

### ❌ NEVER Do:
- Duplicate existing patterns
- Override PrimeVue with :deep() in components
- Hardcode colors/sizes (use design tokens)
- Use !important in scoped styles
- Create custom form/button/card base styles

## Decision Tree

\`\`\`
Need to style a component?
│
├─ Does this pattern exist in another component?
│  ├─ YES → Use global CSS
│  └─ NO → Continue
│
├─ Is this a form/button/card/table?
│  ├─ YES → Use global CSS (components/forms.css, etc.)
│  └─ NO → Continue
│
├─ Is this a PrimeVue component?
│  ├─ YES → Check vendor/primevue-overrides.css
│  └─ NO → Continue
│
└─ Truly unique to this component?
   ├─ YES → Scoped styles OK
   └─ NO → Extract to global pattern
\`\`\`

## Examples

### ❌ Bad: Duplicate Pattern
\`\`\`vue
<style scoped>
.my-card {
  background: var(--color-bg);
  border: 1px solid var(--color-border);
  /* ... duplicating cards.css ... */
}
</style>
\`\`\`

### ✅ Good: Use Global
\`\`\`vue
<template>
  <div class="card">
    <!-- Content -->
  </div>
</template>

<style scoped>
/* No card styles needed */
</style>
\`\`\`

### ❌ Bad: PrimeVue Override
\`\`\`vue
<style scoped>
:deep(.p-inputtext) {
  border: 2px solid #3b82f6 !important;
}
</style>
\`\`\`

### ✅ Good: Global Override
All PrimeVue styling in vendor/primevue-overrides.css

### ✅ Good: Component-Specific
\`\`\`vue
<style scoped>
/* Chart.js canvas sizing (truly component-specific) */
.chart-canvas {
  width: 100% !important;
  height: 100% !important;
}
</style>
\`\`\`

## Code Review Checklist
- [ ] No duplicate patterns from global CSS
- [ ] Design tokens used (no hardcoded values)
- [ ] No :deep() for PrimeVue
- [ ] No !important (except vendor overrides)
- [ ] Scoped styles < 50 lines (rule of thumb)
- [ ] Responsive handled globally when possible
```

**Acceptance Criteria:**
- [ ] Clear decision tree
- [ ] Good/bad examples

**Content:**
```markdown
# CSS System Onboarding Guide

## Welcome to ROA2WEB CSS Architecture

This guide will help you understand our CSS system and start contributing quickly.

## Quick Start (5 minutes)

1. **Read the pattern library:**
   `docs/CSS_PATTERNS.md`

2. **Understand the structure:**
   - `assets/css/core/` - Design tokens, reset
   - `assets/css/patterns/` - Reusable patterns
   - `assets/css/components/` - Component styles
   - `assets/css/vendor/` - Third-party overrides

3. **Golden rules:**
   - ✅ Use global patterns
   - ❌ Don't duplicate CSS
   - ✅ Use design tokens
   - ❌ No hardcoded values
   - ✅ Scoped styles for unique logic only

## Your First Component (15 minutes)

### Example: Creating a Status Badge

1. **Check if pattern exists:**
   ```bash
   grep -r "badge" src/assets/css/
   ```

2. **If not exists, check similarity:**
   - Similar to buttons? Use button patterns
   - Similar to tags? Create new pattern

3. **Create component:**
   ```vue
   <template>
     <span class="badge badge-success">Active</span>
   </template>

   <style scoped>
   /* No badge styles needed - assuming badges.css exists */
   /* Only component-specific layout if needed */
   </style>
   ```

## Common Tasks

### Adding a New Form
→ See `docs/FORM_TEMPLATE.md`

### Creating a Dashboard Card
→ See `docs/CSS_PATTERNS.md` - Card Patterns

### Styling a Table
→ Use `tables.css` classes

### Customizing PrimeVue
→ Edit `vendor/primevue-overrides.css` (NEVER in components)

## Code Review Checklist

Before submitting PR:
- [ ] No CSS duplication
- [ ] Design tokens used
- [ ] No :deep() in components
- [ ] Pattern library consulted
- [ ] Responsive tested
- [ ] Playwright tests pass

**Add section:**
```markdown
## CSS Architecture

ROA2WEB uses a structured CSS system with design tokens and reusable patterns.

### Documentation
- **[CSS Patterns Library](../../docs/CSS_PATTERNS.md)** - All available patterns with examples
- **[Component Styling Guidelines](../../docs/COMPONENT_STYLING.md)** - When to use global vs scoped CSS
- **[Form Template](../../docs/FORM_TEMPLATE.md)** - Standard form structure
- **[Design Tokens](../../docs/DESIGN_TOKENS.md)** - Available CSS variables
- **[Onboarding Guide](../../docs/ONBOARDING_CSS.md)** - Quick start for new developers

### Quick Reference

**CSS Structure:**
```
src/assets/css/
├── core/         # Design tokens, typography
├── patterns/     # Interactive, dashboard, animations
├── components/   # Cards, forms, buttons, tables
├── vendor/       # PrimeVue overrides
└── utilities/    # Spacing, text, flex, colors
```

**Golden Rules:**
- ✅ Use global patterns (check `docs/CSS_PATTERNS.md` first)
- ✅ Use design tokens (`var(--color-primary)` not `#3b82f6`)
- ❌ No `:deep()` PrimeVue overrides in components
- ❌ No CSS duplication
- ❌ No hardcoded values

### Before You Code
1. Check if pattern exists in `docs/CSS_PATTERNS.md`
2. Use design tokens from `core/variables.css` and `core/tokens.css`
3. PrimeVue customization goes in `vendor/primevue-overrides.css`
4. Keep scoped styles minimal (< 50 lines)

### Testing
```bash
npm run test:e2e  # Visual regression tests
```
```

**Acceptance Criteria:**
- [ ] README updated
- [ ] Links to documentation
