Thomas Hallock 9b1d47d4c7 feat(complement-race): implement per-car adaptive opacity for ghost trains ... Ghost train cars now individually adjust opacity based on proximity to local train, reducing visual clutter when overlapping while maintaining clarity when separated. Changes: - Calculate local train car positions array in SteamTrainJourney - Pass positions to GhostTrain for overlap detection - Rewrite GhostTrain to render locomotive and each car separately - Each car calculates opacity independently (0.35 when <20% from any local car, 1.0 otherwise) - Smooth 0.3s CSS transitions between opacity states - Overlap threshold: 20% of track length Benefits: - Reduced clutter when trains overlap - Clear visibility when trains separated - Per-car granularity for mixed scenarios 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>		2025-10-22 13:06:32 -05:00
