- Add isSatelliteFrontFacing() to detect if satellite is on visible side
- Filter satellites in hover and click handlers by front-facing check
- Apply same logic as cables for consistent back-face culling
- Add sizeAttenuation: false to sprite materials for fixed ring size
- Move breathing animation parameters to SATELLITE_CONFIG constants
- Export updateBreathingPhase function to avoid ES module binding issues
- Adjust breathing speed and amplitude for better visual effect
- Calculate orbital period from meanMotion
- Generate predicted orbit points with 10s sampling
- Show complete orbit line when satellite is locked
- Hide orbit when satellite is unlocked
- Color gradient: bright (current) to dark (end)
- Fix TLE epoch format issue with fallback circle orbit
- Add visibility change handler to clear trails on page hide
- Fix satellite count display after loading
- Merge predicted-orbit plan into single file
- Changed trail data structure to {pos, time} with Date.now() timestamp
- Replaced length-based filtering with time-based filtering (5 second window)
- Trail now naturally clears when page returns to foreground
- No more ugly frame-skipping or visibilitychange workarounds
Build: passes
- Fill unfilled trail points with satellite position instead of (0,0,0)
- Update toggle-satellites button state after auto-show on init
- Remove trailsReady flag since it's no longer needed
- Change satellite points from squares to circular dots
- Add hover ring (white) and lock ring (yellow) for satellites
- Fix satellite hover/lock ring state management
- Dim all cables when satellite is locked
- Increase MAX_SATELLITES to 2000
- Fix satIntersects scoping bug
