Debugging headless browsers is indeed a nightmare sometimes! One tool that saved me is Puppeteer Recorder—it captures actions and generates code snippets, which helps trace issues faster.
Also, for sites blocking headless mode, try adding `--disable-blink-features=AutomationControlled` in Chrome flags. Some sites also check for `navigator.webdriver`, so overriding that in your script might help.
Dynamic content? Yeah, that’s a classic. I usually add explicit waits or use `page.waitForSelector()` with custom timeouts.
