Sep 1, 2025September 2025 performance highlights for HSLdevcom/digitransit-ui. Focused on front-end ticket link visibility improvements to improve user experience and testing parity. Implemented a Ticket Link Visibility Configuration with conditional rendering based on externalFareRouteIds, and removed environment-specific gating to ensure ticket link visibility across testing environments. This work reduces manual UI tweaks and QA variance while aligning with product goals for external fares; lays groundwork for more granular route-level UI controls.
