+// - the bin script points at dist/src/cli.js, but the package ships dist/cli.js
+// - the compiled date-holidays import expects a synthetic default export
+// - some TfL journeys reference timing links without matching route-link geometry
+//
+// GTFS shapes are optional for R5 routing. Clear shape references and omit
+// shapes.txt so missing route geometry does not drop otherwise usable trips.
