-// - pw_start: Start browser (only if not already running)
-// - pw_stop: Stop browser (only when you're truly done and browser is no longer needed)
-// - pw_is_running: Check if browser is running
-// - pw_navigate: Go to a URL
-// - pw_click: Click an element by CSS selector
-// - pw_fill: Type text into an input
-// - pw_extract_text: Get text from page/element
-// - pw_screenshot: Take a screenshot (returns file path)
-// - pw_screenshot_and_view: Take screenshot with image for viewing
-// - pw_wait_for_selector: Wait for element to appear
-// - pw_drag: Drag mouse from one point to another
-// - pw_click_at: Click at X,Y coordinates
-// - pw_get_html: Get HTML content
-// - pw_get_dom: Get structured DOM tree
