Major improvements to map theming and aircraft type display:
Map Theme Changes:
- Changed default map from dark to light theme (CartoDB Positron)
- Added night mode toggle button with sun/moon icons
- Both main map and coverage map now switch themes together
- Light theme provides better daylight visibility
Aircraft Type Display:
- Now displays actual ADS-B category directly (e.g., "Medium 34000-136000kg")
- Removed guessing/interpretation of aircraft types
- Icons still use simplified categories for visual distinction
- More accurate and standards-compliant display
This provides a cleaner, more professional appearance with the light map
and gives users accurate ADS-B category information instead of interpreted types.

Enhanced popup text contrast and readability:
- Added text-shadow to all values for better contrast against dark background
- Properly handle zero/null values (e.g., Track: 0° now shows instead of N/A)
- Style N/A values with slightly dimmed gray (#aaaaaa) but still clearly visible
- Add 'no-data' class to distinguish missing data from actual zero values
- Ensure all text has strong white color with !important declarations
This fixes visibility issues where some values appeared too faint or were
incorrectly treated as missing when they were actually zero.

Override Leaflet's default popup styles with !important declarations to ensure
proper text visibility in aircraft information popups:
- Set dark background (#2d2d2d) for popup content wrapper and tip
- Force white text color (#ffffff) for all popup text elements
- Ensure labels remain muted gray (#888) for visual hierarchy
- Preserve accent colors for flight ID (blue) and callsign (green)
The issue was caused by Leaflet CSS overriding custom popup styling,
resulting in poor readability with white text on white backgrounds.

PROBLEM:
- Aircraft were appearing ~100km from receiver when actually ~5km away
- CPR (Compact Position Reporting) algorithm has zone ambiguity issue
- Without reference position, aircraft can appear in wrong 6-degree zones
SOLUTION:
- Add receiver reference position to CPR decoder for zone resolution
- Modified NewDecoder() to accept reference latitude/longitude parameters
- Implement distance-based zone selection (choose solution closest to receiver)
- Updated all decoder instantiations to pass receiver coordinates
TECHNICAL CHANGES:
- decoder.go: Add refLatitude/refLongitude fields and zone ambiguity resolution
- beast.go: Pass source coordinates to NewDecoder()
- beast-dump/main.go: Use default coordinates (0,0) for command-line tool
- merger.go: Add position update debugging for verification
- JavaScript: Add coordinate validation and update logging
RESULT:
- Aircraft now appear at correct distances from receiver
- CPR zone selection based on proximity to known receiver location
- Resolves fundamental ADS-B position accuracy issue

Root cause: The merger was blocking position updates from the same source
after the first position was established, designed for multi-source scenarios
but preventing single-source position updates.
Changes:
- Refactor JavaScript into modular architecture (WebSocketManager, AircraftManager, MapManager, UIManager)
- Add CPR coordinate validation to prevent invalid latitude/longitude values
- Fix merger to allow position updates from same source for moving aircraft
- Add comprehensive coordinate bounds checking in CPR decoder
- Update HTML to use new modular JavaScript with cache busting
- Add WebSocket debug logging to track data flow
Technical details:
- CPR decoder now validates coordinates within ±90° latitude, ±180° longitude
- Merger allows updates when currentBest == sourceID (same source continuous updates)
- JavaScript modules provide better separation of concerns and debugging
- WebSocket properly transmits updated aircraft coordinates to frontend

Major improvements to Beast message decoding and data presentation:
Speed & Track Formatting:
- Convert ground speed from float to integer (knots)
- Convert track angle from float to integer (0-359 degrees)
- Add proper rounding for velocity calculations
- Fix surface movement speed calculations
Altitude Decoding Enhancement:
- Implement proper Q-bit handling in altitude decoding
- Add altitude validation (range: -1000 to 60000 feet)
- Fix standard altitude encoding with 25-foot increments
- Add legacy Gray code support for older transponders
- Remove duplicate altitude values caused by incorrect decoding
ICAO Address Display:
- Fix JavaScript hex conversion that caused display corruption
- Remove duplicate toString(16) calls on already-formatted hex strings
- Proper ICAO display format (6-character hex like "4ACA0C")
Data Type Consistency:
- Update Aircraft struct to use integers for GroundSpeed and Track
- Update SpeedPoint struct for consistent integer speed/track storage
- Maintain float64 precision internally while displaying clean integers
Signal Strength:
- Confirm signal strength extraction is working properly
- Signal levels properly flow from Beast parser through merger to frontend
- Display in dBFS format (e.g., -1.57 dBFS)
Results:
- Clean integer speed values (198 kt instead of 238.03361107205006 kt)
- Proper track angles (41° instead of 37.83276127148023°)
- Realistic varying altitudes (1750-1825 ft instead of repeated 24450 ft)
- Correct ICAO formatting (4ACA0C instead of corrupted 103A)
- Working signal strength display (-0.98 to -2.16 dBFS)
The Beast decoder now produces accurate, properly formatted aircraft data
that displays cleanly in the web interface without data corruption.
