# Hover Micro-interactions

## Что это
Микровзаимодействия при наведении: плавные изменения масштаба, тени, свечения бордера, цветового сдвига. Создают ощущение живого интерфейса.

## Типы hover-эффектов

### 1. Card Lift + Shadow
```css
.card {
  transition: transform 0.3s ease, box-shadow 0.3s ease;
}
.card:hover {
  transform: translateY(-4px);
  box-shadow: 0 20px 40px rgba(0, 0, 0, 0.3);
}
```

### 2. Border Glow
```css
.card {
  border: 1px solid var(--color-border);
  transition: border-color 0.3s ease;
}
.card:hover {
  border-color: var(--color-accent);
  box-shadow: 0 0 20px rgba(99, 102, 241, 0.2);
}
```

### 3. Image Zoom
```css
.image-wrapper {
  overflow: hidden;
  border-radius: 16px;
}
.image-wrapper img {
  transition: transform 0.5s ease;
}
.image-wrapper:hover img {
  transform: scale(1.05);
}
```

### 4. Text Color Shift
```css
.link {
  color: var(--color-text-secondary);
  position: relative;
  transition: color 0.3s ease;
}
.link:hover {
  color: var(--color-accent);
}
.link::after {
  content: '';
  position: absolute;
  bottom: -2px;
  left: 0;
  width: 0;
  height: 2px;
  background: var(--color-accent);
  transition: width 0.3s ease;
}
.link:hover::after {
  width: 100%;
}
```

### 5. Icon Rotation/Swing
```css
.icon {
  transition: transform 0.3s ease;
}
.icon:hover {
  transform: rotate(15deg) scale(1.1);
}
```

## Magnetic Hover (Enhanced)

```css
.hover-magnetic {
  transition: transform 0.2s ease;
}
.hover-magnetic:hover {
  transform: scale(1.02);
}
```

```javascript
document.querySelectorAll('.hover-magnetic').forEach(el => {
  el.addEventListener('mousemove', (e) => {
    const rect = el.getBoundingClientRect();
    const x = (e.clientX - rect.left) / rect.width - 0.5;
    const y = (e.clientY - rect.top) / rect.height - 0.5;
    el.style.transform = `perspective(500px) rotateY(${x * 10}deg) rotateX(${-y * 10}deg) scale(1.02)`;
  });
  el.addEventListener('mouseleave', () => {
    el.style.transform = 'perspective(500px) rotateY(0) rotateX(0) scale(1)';
  });
});
```

## Anti-patterns

| ❌ Плохо | ✅ Хорошо |
|----------|-----------|
| `transform: scale(1.2)` — слишком резко | `transform: scale(1.02–1.05)` |
| Без `transition` | `transition: all 0.3s ease` |
| Без `will-change` на тяжёлых | `will-change: transform` |
| Hover на touch-устройствах | `@media (hover: hover)` |

## Mobile Detection

```css
@media (hover: none) {
  .hover-effect:hover {
    transform: none;
  }
}
```

## CV Service Validation

```bash
curl -s -X POST http://localhost:8001/design/analyze \
  -H "Content-Type: application/json" \
  -d '{"image_base64": "...", "full_analysis": false}' | python3 -c "
import sys, json
d = json.load(sys.stdin)
motion = d['dimensions'].get('motion_quality', {})
print(f\"Motion Quality: {motion.get('score', 'N/A')}/10\")
"
```

Ожидается: `motion_quality` > 6.
