Thank you for this. I just tried it out and it worked perfectly with no problems. Previously I was planning to go into Chrome's developer tools and entering "window.scrollY" in the console to get the scroll position of the .htm page, taking a screenshot of where I stopped reading, then the next day going back into developer tools and entering window.scrollTo(0, 175000), with "175000" replaced by yesterday's scroll position.

A bit surprised that Anthropic doesn't have an investor relations section with user-friendly links to their filings.
