Browser-extension automation cant save page screenshots to disk

A DOM-driving browser extension (e.g. Claude-in-Chrome) cannot interact with Chrome print-preview or native OS save dialogs, so you cannot save a rendered page/email as PDF or PNG from a logged-in session that way. macOS screencapture via shell also fails with could not create image from display unless the terminal has Screen Recording permission. To get an authenticated web page as a file, extract text/HTML via get_page_text and rebuild it, or have the user capture manually dont promise screenshot-to-disk from an authenticated session.
