## 🔍 WHAT EACH FILE DOES

### `client_intelligence_helper.py`
**In One Sentence**: Analytics engine that calculates client metrics and generates smart product recommendations.

**What It Calculates**:
```
1. Revenue (3-year breakdown)
2. Product mix (revenue by line)
3. Margins (avg %, total €)
4. Purchase frequency (orders/year)
5. AOV (avg revenue per order)
6. Last visit date
7. Similar clients (±25% revenue)
8. Missing product recommendations
```

**How to Use It**:
```python
from client_intelligence_helper import generate_client_intelligence_profile

# Pass data to main function
profile = generate_client_intelligence_profile(
    all_sales_df,      # Your full sales DataFrame
    "José Silva",      # Client name
    visit_logs_df      # Optional visit logs
)

# Use profile in template
# profile['revenue_3years']
# profile['product_mix']
# profile['margin']
# profile['frequency']
# profile['recommendations']
```

### `templates/client_intelligence.html`
**In One Sentence**: Beautiful, responsive HTML dashboard displaying client analytics and recommendations.

**What It Displays**:
- Header with client name and last visit
- 4 KPI cards at top
- Revenue chart (3-year trend)
- Product mix chart
- Recommendation cards
- Action buttons (back, details, visit)

**How It Works**:
```html
<!-- Receives 'profile' dict from Flask route -->
<!-- Renders data with Jinja2 templating -->
<!-- Chart.js creates interactive charts -->
<!-- Bootstrap handles responsive design -->
```

### `/client-intelligence` Route (in app.py)
**In One Sentence**: Flask HTTP endpoint that loads data and renders Client Intelligence Panel.

**What It Does**:
1. Validates authentication (`@login_required`)
2. Checks authorization (RBAC)
3. Loads sales data from Google Sheets
4. Optionally loads visit logs
5. Calls `cih.generate_client_intelligence_profile()`
6. Renders `client_intelligence.html` template
7. Returns HTML to browser

**How to Access**:
```
GET /client-intelligence?cliente=José%20Silva
→ Loads Client Intelligence Panel for José Silva
```
