Add your Google Maps API key

This planner needs your own key to load the live map, route lines, and place photos. Open this file in a text editor and paste your key into the line near the top:

const GOOGLE_API_KEY = "PASTE_YOUR_KEY_HERE";

1. In Google Cloud Console, enable Maps JavaScript API, Directions API, and Places API.
2. Create an API key under Credentials.
3. Restrict it: Application = Websites, and limit API restrictions to those three.
4. Paste it into the file, save, and reload.

Your key stays in your copy of the file — keep it private.
