// These are the "selectors" we'll use to find the button. They are like a precise address for an element on a webpage.
// I've included several common ones for different download pages on the site.
const DOWNLOAD_BUTTON_SELECTORS = [
'a.btn.btn-primary.btn-lg', // The main "Download now" button
'button[type="submit"]', // A common fallback for form-based downloads
'a[href*="/download/"]' // A general selector for links containing "/download/"
];

* Finds and clicks the first available download button from our list of selectors.
* @returns {boolean} - True if a button was found and clicked, otherwise false.

// --- The Magic: MutationObserver ---
// This is our smart listener. It waits for changes in the webpage's HTML.

// --- Script Execution ---
// Try to click the button immediately when the script runs.
// This handles cases where the page loads fast and the button is already there.

// If the button isn't there yet, we start our observer.
// We tell it to watch the entire body of the page for new elements being added.
