    // --- Configuration ---
    // 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.
     */
    const clickDownloadButton = () => {
        for (const selector of DOWNLOAD_BUTTON_SELECTORS) {
            const downloadBtn = document.querySelector(selector);
            if (downloadBtn) {
                console.log(`Found download button with selector: "${selector}". Clicking it now!`);
                downloadBtn.click();
                return true; // Found and clicked, our job is done.
            }
        }
        console.log('Waiting for a download button to appear...');
        return false; // No button found yet.
    };

    // --- The Magic: MutationObserver ---
    // This is our smart listener. It waits for changes in the webpage's HTML.
    const observer = new MutationObserver((mutationsList, obs) => {
        // We run our click function every time the page changes.
        if (clickDownloadButton()) {
            console.log('Success! Disconnecting the observer to save resources.');
            obs.disconnect(); // Stop watching once we've clicked the button.
        }
    });

    // --- 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 (!clickDownloadButton()) {
        // 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.
        console.log('Button not found immediately. Starting MutationObserver to wait for it.');
        observer.observe(document.body, {
            childList: true, // Watch for direct children being added or removed
            subtree: true    // Watch all descendants, not just direct children
        });
    }
