## 🎯 Completed Tasks

### 1. ✅ Earthquake Animation (v1.1.0)
**Feature:** Animated new earthquake detection

**Implementation:**
- **Growing Dot**: New earthquakes animate from 0 to full size (0.6s)
- **Pulse Ring**: Expanding circular ring (50km radius, 3s animation)
- **🆕 Badge**: New quakes marked in popup
- **Tracking**: `previousQuakeIds` ref tracks seen earthquakes
- **CSS Animations**: Added to `src/styles/main.css`

**CSS Keyframes:**
```css
@keyframes earthquake-pulse {
  0% { transform: scale(1); opacity: 0.8; }
  100% { transform: scale(3); opacity: 0; }
}

@keyframes earthquake-grow {
  0% { transform: scale(0); opacity: 0; }
  50% { transform: scale(1.5); opacity: 1; }
  100% { transform: scale(1); opacity: 1; }
}
```

**User Experience:**
- Immediate visual notification of new seismic events
- Helps operators spot fresh earthquakes at a glance
- Animation plays once, then marker remains static
- No performance impact (CSS-based)
