# Logo & Burger Button Refinement

## 🎯 Objectifs
1. **Réduire les bordures du logo** (trop imposantes)
2. **Logo mobile à gauche** (pas centré)
3. **Burger button complètement refait** (respecte les règles CSS premium)

## ✅ Changements

### 1. Logo Desktop - Bordures Réduites

**Avant:**
```scss
padding: 10px 18px;
border-radius: 16px;
border: 1px solid rgba(99, 102, 241, 0.2);
background: linear-gradient(...);
```

**Après:**
```scss
padding: 8px 14px;          // Réduit de 10/18 → 8/14
border-radius: 12px;         // Réduit de 16 → 12
border: none;                // Supprimé
background: rgba(99, 102, 241, 0.06);  // Simplifié, plus subtil
```

**Shadows:**
```scss
// Avant: 4 couches complexes
box-shadow: 
  0 4px 12px rgba(99, 102, 241, 0.12),
  0 2px 6px rgba(139, 92, 246, 0.08),
  inset 0 1px 0 rgba(255, 255, 255, 0.15);

// Après: 2 couches subtiles
box-shadow: 
  0 2px 8px rgba(99, 102, 241, 0.08),
  inset 0 1px 0 rgba(255, 255, 255, 0.08);
```

**Hover:**
```scss
// Avant: translateY(-2px)
transform: translateY(-2px);

// Après: translateY(-1px) - plus subtil
transform: translateY(-1px);
```

### 2. Logo Mobile - Position à Gauche

**Avant:**
```scss
.app-shell__mobile-logo {
  position: fixed;
  top: 12px;
  left: 50%;
  transform: translateX(-50%);  // Centré
}
```

**Après:**
```scss
.app-shell__mobile-logo {
  position: fixed;
  top: 12px;
  left: 16px;      // À gauche
  // Pas de transform
}
```

**Bordures Réduites (Mobile):**
```scss
:deep(.app-brand) {
  padding: 6px 12px;      // Réduit de 8/16 → 6/12
  border-radius: 12px;    // Réduit de 20 → 12
  border: none;           // Supprimé
  background: rgba(99, 102, 241, 0.08);  // Simplifié
  backdrop-filter: blur(16px) saturate(140%);  // Réduit de 24 → 16
}

:deep(.app-brand__icon) {
  width: 28px;   // Réduit de 32 → 28
  height: 28px;
}
```

**Light Mode (Simplifié):**
```scss
html[data-theme="light"] .app-shell__mobile-logo {
  :deep(.app-brand) {
    background: rgba(255, 255, 255, 0.9);
    backdrop-filter: blur(16px) saturate(140%);
    border: none;
    box-shadow: 
      0 2px 8px rgba(15, 23, 42, 0.06),
      inset 0 1px 0 rgba(255, 255, 255, 0.5);
  }
}
```
