- Added High Vortex Large as distinct category in legend
- Assigned red-orange color (#ff4500) to differentiate from regular Large
- Updated JavaScript to check for high vortex before regular large
- Maintains proper ADS-B category distinctions for wake turbulence
High Vortex Large aircraft (like B757) create stronger wake turbulence
than typical large aircraft, warranting visual distinction for safety.

**Transponder Display Improvements:**
- Simplified transponder capability labels to be more concise
- "Level 2+ Transponder" → "Level 2+"
- "Enhanced Transponder" → "Enhanced"
- "Alert/Emergency Status" → "Alert/Emergency"
- Removes redundant "Transponder" suffix for cleaner popup display
**New Signal Quality Feature:**
- Added SignalQuality field combining NACp, NACv, and SIL into human-readable assessment
- Quality levels: "Excellent", "Good", "Fair", "Poor" based on aviation standards
- Prioritizes surveillance integrity (SIL) then position accuracy (NACp)
- Automatically calculated when operational status messages (TC 31) are received
- Displayed in aircraft popup when available
**Signal Quality Algorithm:**
- **Excellent**: High integrity (SIL ≥ 2) with precise position (NACp ≥ 9)
- **Good**: Good integrity with moderate accuracy OR very high accuracy
- **Fair**: Some integrity with basic accuracy OR high accuracy without integrity
- **Poor**: Low but usable quality indicators
- **Empty**: No quality data available
**Frontend Enhancements:**
- Added "Signal Quality" row to aircraft popup
- Only displays when quality data is available
- Clean integration with existing popup layout
- Shows alongside transponder information
**Data Quality Context:**
- NACp: Position accuracy (0-11, higher = more precise location)
- NACv: Velocity accuracy (0-4, higher = more precise speed/heading)
- SIL: Surveillance integrity (0-3, higher = more reliable data)
This gives users a quick understanding of data reliability without needing
to interpret technical NACp/NACv/SIL values directly.

Add dedicated transponder fields to prevent Mode S decoder from overwriting
the aircraft Category field with transponder capability information.
**Problem Fixed:**
- DF11 All-Call Reply messages were setting aircraft.Category to "Enhanced Transponder"
- This overwrote the actual aircraft type (Light, Medium, Heavy, etc.) from ADS-B
- Users saw "Enhanced Transponder" instead of proper aircraft classification
**Solution:**
- Added dedicated TransponderCapability and TransponderLevel fields to Aircraft struct
- Updated JSON marshaling to include new transponder fields
- Modified decodeAllCallReply() to use dedicated fields instead of Category
- Enhanced popup display to show transponder info separately from aircraft type
- Removed Category overwriting in decodeCommD() for DF24 messages
**New Aircraft Fields:**
- TransponderCapability: Human-readable capability description
- TransponderLevel: Numeric capability level (0-7)
**Popup Display:**
- Aircraft type now shows correctly (Light, Medium, Heavy, etc.)
- Transponder capability displayed as separate "Transponder:" field when available
- Only shows transponder info when DF11 messages have been received
**Data Quality Indicators Clarification:**
- NACp: Navigation Accuracy Category - Position (0-11, higher = more accurate)
- NACv: Navigation Accuracy Category - Velocity (0-4, higher = more accurate)
- SIL: Surveillance Integrity Level (0-3, higher = more reliable)
Users now see both proper aircraft classification AND transponder capability
information without conflicts between different message types.

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

- 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.
