Conversation and character pages that mark which lines your own playthrough has read

Once you open your save, conversation and character pages offer a My playthrough reading mode. Lines your run has read show as normal, and lines you missed are hidden behind a Reveal control, with a count of what you missed by speaker. A conversation you never opened hides everything, including its title. Each character on Your playthrough links straight to what you missed with them.

After you sign in, your kept run is also saved to your account, so another browser shows it too. The newer save always wins in both places, and if saving to your account fails, your browser copy stays and you can retry.

Nothing new is downloaded to show the marks, since your run is already in your browser.
