How I Built Map Route Polylines & a Clean Country-Code Picker

In this one I walk through drawing route polylines on the map — connecting stops into clean, accurate route lines — and building a proper country-code picker for phone input. I cover how the polyline rendering works, the edge cases I ran into, and how I'm handling country codes so numbers validate correctly across regions.
