* Refactor aircraft photo and hero banner components to reset loading state on photo change - Updated Lightbox component to reset image loading state when navigating between photos. - Modified HeroBanner component to reset loading state when the photo changes. Clean up control panel search logic - Removed unnecessary hasResults variable in SearchContent component. Implement flight API client with fallback mechanism - Added flight-api-client to handle fetching flight data from multiple sources (airplanes.live, adsb.lol, OpenSky). - Introduced flight-api-parsing module to convert raw API responses into standardized FlightState objects. - Created flight-api-types for shared types between API responses. Refactor useFlights hook to utilize new flight API client - Updated useFlights hook to fetch flights using the new flight API client. - Removed credit management logic as it is no longer applicable with the new API structure. Fix useFlightMonitors to fetch flight data by hex address - Changed useFlightMonitors to use fetchFlightByHex instead of fetchFlightByIcao24. Update geo utility function for better readability - Refactored splitAtAntimeridian function to improve variable naming and clarity. Enhance OpenSky types with additional fields - Added typeCode and registration fields to FlightState type for better integration with readsb data. * fix: correct 6 files that diverged during rebase (iata code, globe mode ref, terrain attribution, cache eviction, opensky parsing) * fix: improve keyboard shortcuts help focus trapping feat: add showAirspace option to MapAttribution component fix: clear hideTimer on ScrollArea cleanup refactor: change pendingFpvRef to MutableRefObject in useFlightMonitors fix: handle sessionStorage availability in useFlightTrack refactor: increase POLL_INTERVAL_MS in useFlights for better performance fix: optimize keyboard shortcuts dialog check refactor: optimize useMergedTrails by caching selected flight position feat: extend Settings type with airspace options refactor: improve airline logo normalization functions refactor: enhance flight API client with serialized rate limiting refactor: optimize registration country lookup with pre-built maps refactor: enhance logo cache management with size limits feat: update map attribution to include airspace option fix: validate rawState in parseStateRow function refactor: improve utility functions with clamp implementation * feat: add ATC lookup functionality and GPU memory monitoring - Implemented ATC lookup functions in `atc-lookup.ts` for converting IATA to ICAO codes, finding nearby ATC feeds, and looking up ATC feeds by code. - Introduced `atc-types.ts` to define types and priorities for ATC feeds. - Added GPU memory monitoring in `gpu-memory-monitor.ts` to track WebGL resource allocations and provide memory reports. - Enhanced trail stitching logic in `trail-stitching.ts` by adding a function to clear the splined track cache and optimizing altitude checks. * feat: enhance flight data handling and improve API resilience - Implemented a maximum empty response streak guard in useFlights to prevent data loss during transient API failures. - Added immediate fetch on network reconnect in useFlights to ensure timely data retrieval. - Updated useMergedTrails to include timestamps for trail points. - Removed smoothAnimations setting from useSettings as it is no longer needed. - Enhanced useTrailHistory to preserve last-known trails during empty flight responses and added dynamic jump detection for tab resume scenarios. - Improved flight API client with a circuit breaker mechanism to handle provider failures and prevent excessive retries. - Updated flight API parsing to reject non-JSON responses from OpenSky and other providers. - Enhanced trail smoothing and stitching logic to ensure better continuity at junctions between historical and live data. * feat: migrate aircraft models to Cloudinary CDN and update mapping logic * fix: adjust UI component styles and improve trail smoothing parameters * fix: adjust base aircraft size for improved rendering * feat: update changelog with recent enhancements and modify data source attribution * fix: update model optimization details and remove Draco compression dependency * feat: update changelog with recent code review fixes and fallback provider adjustments
