December 2025: Delivered user-centric transport enhancements and hardened deployment practices. Key deliverables include the Funicular Transport Mode rollout with UI updates, icons, and Norwegian localization, plus transportMode-aware querying to display the correct icon for funicular stops. Also completed configuration management cleanup by removing legacy environment files and centralizing Firebase configuration to improve security and reduce deployment risk. A bug fix in postal address construction (createPostalAddress) ensures postal addresses are returned correctly, preventing downstream address errors. These efforts improve user clarity for transit options, strengthen security and maintainability, and ensure data correctness across services.
