Fixed an issue where the letter R could look like the number 9.
Repositioned taxiways that were covering runway numbers and threshold markings.
Improved taxiway connections at runway ends.
Adjusted curved taxiway centerlines and holding-position markings.
Restored existing gate guidance lines that were unintentionally removed.
Added missing gate-to-taxiway guidance line connections.
