🛠 How to Run Locally

You must use a local server (not just open the HTML file directly), because JavaScript modules and API fetches require it.

Option 1: Using VS Code + Live Server plugin

1. Open the project folder in Visual Studio Code
2. Install the extension: Live Server by Ritwick Dey
3. Right-click index.html → Open with Live Server
4. App runs on: http://localhost:5500

Option 2: Using Python (if installed)

# In the project root folder
python -m http.server
