## 🗺️ Map Integration - Complete Flow

### Question: Will the map appear on the frontend?

**Answer: YES! ✅**

### How It Works:

#### Option A: With Coordinates (Precise)
```
Admin:
1. Paste Google Maps/Mapy.cz link in MapLinkImporter
2. Coordinates extracted automatically
3. Map preview appears in admin
4. Add location name
5. Save

Frontend:
→ EventLocationMap uses location name
→ Geocodes to coordinates
→ Shows map with club colors
→ Precise location!
```

#### Option B: Without Coordinates (Quick)
```
Admin:
1. Type location name: "Sportovní hala TJ Sokol"
2. Save (no coordinates needed)

Frontend:
→ EventLocationMap geocodes the name
→ Shows map with club colors
→ Works automatically!
```

### Result:
- ✅ **Map ALWAYS shows** if location is set
- ✅ **Club colors applied** (primary for marker, accent for elements)
- ✅ **Responsive** on mobile
- ✅ **Interactive** - zoom, pan
