Make every new page I load look like this, or a slightly cleaned up or mobile-specific version.
We don't currently have a way to provide a reference during generation, but if I were you, I'd personally try downloading the old page archive and a new page archive, throw them both in codex/claude code as context and see what it can come up with. Wouldn't be surprised if it could do a decent job writing a converter.
Somewhat tangential: I have had luck with more generic retheming, e.g. "Turn Google into a 1970s era CLI " (https://www.tweeks.io/share/script/8c8c0953f6984163922c4da7) or "Turn LinkedIn into a 90s era Neocities site" These aren't the most useful, but they are fun!
