// Option 1: Immediately initialize with default config
// function run() { init(); }

// Option 2: Expose init globally to allow custom config injection (Recommended for flexibility)

  // or just require manual initialization from the HTML.
  // For simplicity, we'll require manual init call from HTML when using custom config.
  // If you always want it to run with defaults unless overridden, you could do:
