## Simple and Safe Bandwidth Optimization
### Single Line Change
- Added `EnableCompression: true` to WebSocket upgrader
- Enables automatic deflate compression for all WebSocket messages
- No other code changes required
### Expected Benefits
- 60-90% reduction in WebSocket message size
- Automatic compression/decompression handled by browser and Go
- Particularly effective for JSON data with repeated field names
- No impact on functionality or reliability
### Why This Approach
- Minimal risk - single configuration flag
- Immediate benefits without complex logic
- Built-in browser and Go support
- No client-side changes needed
- Easy to disable if issues arise
This provides significant bandwidth savings with zero complexity,
allowing us to evaluate the impact before considering more advanced
optimizations.

The embedded files debug output was showing on every database page visit,
cluttering the logs with unnecessary information. Made it conditional on
the -verbose flag to reduce noise in production logs.
Changes:
- Added 'debug' field to Server struct
- Updated NewWebServer constructor to accept debug parameter
- Pass verbose flag from main.go to server constructor
- Made debugEmbeddedFiles() conditional on debug flag
Now debug output only appears when -verbose flag is used, keeping
normal operation clean while preserving debugging capability.

Track and display the number of active WebSocket connections viewing the
aircraft tracker. Features:
Backend:
- Add getActiveClientCount() method for thread-safe client counting
- Include active_clients count in all statistics responses
- Integrate with existing stats API endpoints
Frontend:
- Display "X viewer(s)" in header stats with proper plural/singular grammar
- Add "Active Viewers" card to Statistics view
- Real-time updates as clients connect/disconnect
- Fallback to 1 when stats not yet available
This adds a social element showing "Now being watched by X users" style
information prominently in the interface.

- Run go fmt on all Go code (server.go formatting cleanup)
- Fix shellcheck issues in build-deb.sh script:
- Replace indirect exit code checks ($?) with direct command checks
- Use 'if ! command' instead of 'if [ $? -ne 0 ]'
- Use 'if command' instead of 'if [ $? -eq 0 ]'
- All quality checks now pass:
- go fmt: ✅ Code properly formatted
- go vet: ✅ No issues found
- shellcheck: ✅ All shell scripts validated
- go test: ✅ No test failures (no tests yet)
Follows project guidelines for shell script validation and code quality.

Cleanup:
- Remove unused aircraft-icon.svg (replaced by type-specific icons)
- Remove test files: beast-dump-with-heli.bin, beast.test, main, old.json, ux.png
- Remove duplicate config.json.example (kept config.example.json)
- Remove empty internal/coverage/ directory
- Move CLAUDE.md to project root
- Update assets.go documentation to reflect current icon structure
- Format all Go code with gofmt
Server Host Binding Fix:
- Fix critical bug where server host configuration was ignored
- Add host parameter to Server struct and NewWebServer constructor
- Rename NewServer to NewWebServer for better clarity
- Fix IPv6 address formatting in server binding (wrap in brackets)
- Update startup message to show correct bind address format
- Support localhost-only, IPv4, IPv6, and interface-specific binding
This resolves the "too many colons in address" error for IPv6 hosts like ::1
and enables proper localhost-only deployment as configured.

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

Backend Changes:
- Added OriginConfig struct to server package
- Modified NewServer to accept origin configuration
- Added /api/origin endpoint to serve origin data to frontend
- Updated main.go to pass origin configuration to server
Frontend Changes:
- Modified initializeMap() to fetch origin from API before map creation
- Updated initializeCoverageMap() to also use origin data
- Added fallback coordinates in case API request fails
- Maps now center on the calculated origin position instead of hardcoded coordinates
The map now properly centers on the calculated average position of enabled
sources (or manually configured origin), providing a much better user experience
with appropriate regional view.
