## 🔤 2. Fluid Typography

```css
:root {
  --fluid-sm: clamp(0.875rem, 0.8rem + 0.35vw, 1rem);
  --fluid-base: clamp(1rem, 0.9rem + 0.5vw, 1.125rem);
  --fluid-lg: clamp(1.25rem, 1rem + 1vw, 1.5rem);
  --fluid-xl: clamp(1.5rem, 1.2rem + 1.5vw, 2rem);

## ⚙️ 5. User Preferences

## 🔄 Workflow

> **Kaynak:** [MDN - Container Queries](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Containment/Container_Queries) & [Utopia - Fluid Responsive Design](https://utopia.fyi/)

### Aşama 1: Viewport & Layout Strategy
- [ ] **Mobile First**: Tasarımı en küçük ekran boyutundan başlayarak kurgula.
- [ ] **Breakpoints Selection**: Cihaz bazlı değil, içerik bazlı (Content-driven) kırılma noktaları belirle.
- [ ] **Fluid Scaling**: Typography ve spacing için `clamp()` fonksiyonlarını hesapla ve entegre et.

### Aşama 2: Modern CSS Implementation
- [ ] **Container Queries**: Komponentlerin içindeki bulundukları alana göre (Viewport değil) şekil almasını sağla.
- [ ] **Grid/Flex Optimization**: Kompleks layout'lar için `CSS Grid` (Area naming) ve `Flexbox` (Gap) kullan.
- [ ] **Image Optimization**: `srcset` ve `aspect-ratio` kullanarak görsel yüklemelerini ve düzenini optimize et.

### Aşama 3: Performance & Accessibility Audit
- [ ] **Lighthouse Check**: Core Web Vitals (LCP/CLS) metriklerini mobil için optimize et.
- [ ] **Interaction Check**: Dokunmatik (Touch) alanların yeterli boyutta (min 44x44px) olduğunu doğrula.
- [ ] **User Preferences**: `prefers-color-scheme` ve `prefers-reduced-motion` desteğini test et.

### Kontrol Noktaları
| Aşama | Doğrulama |
|-------|-----------|
| 1 | Tasarım 320px (iPhone SE) ve 2560px (Ultra-wide) arasında sorunsuz mu? |
| 2 | Horizontal scroll oluşuyor mu? (Overflow kontrolü) |
| 3 | Font boyutları her viewport'ta okunabilir mi? |
