This is a simple Express + EJS app (no React) that fetches a list of jamatkhanas from a JSON endpoint,
lets users search by text, and optionally sort/filter by distance when coordinates are available.
Tips
Click Use my location to fill lat/lng, then press Search to sort by distance.
Change the radius to filter results within that many miles (when coordinates exist).
Set JK_SOURCE_URL to point to your own endpoint if you host the data elsewhere.
