Subject: [PATCH] feat: WSPR v1.4.3 - Add separate opacity controls for paths
 and heatmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

✨ New Feature:
- Added two independent opacity sliders in filter panel
  * Path Opacity: Controls propagation paths and station markers (10-100%)
  * Heatmap Opacity: Controls density heatmap circles (10-100%)
- Users can now fine-tune path visibility without affecting heatmap
- Each opacity slider has live value display (shows percentage)

🎨 UI Improvements:
- Added visual separators between control groups
- Path opacity slider with live update (shows 70% default)
- Heatmap opacity slider with live update (shows 60% default)
- Clean organization: Filters → Opacity → Toggles

🔧 Technical Changes:
- Added pathOpacity state (default: 0.7)
- Added heatmapOpacity state (default: 0.6)
- Removed global opacity prop dependency
- Path/marker rendering uses pathOpacity
- Heatmap circles use heatmapOpacity
- Event listeners for both opacity sliders
- Updated filter return object to include both opacities
- Removed old opacity update useEffect (no longer needed)

📊 Benefits:
- Better control over layer visibility
- Can dim paths while keeping heatmap visible
- Can dim heatmap while keeping paths clear
- No more conflict between path and heatmap opacity
- Smooth real-time opacity updates

Version: 1.4.2 → 1.4.3
