This is super cool, well done!
Some fun historical context: the 74181 chip (part of the 74HC series) was one of the key technologies behind the Xerox Alto. It was the first complete ALU on a single chip using a medium-scale integration (MSI) design. This was what enabled the Alto to be much smaller than minicomputers like the PDP-8, which used small-scale integration (SSI) that spread the processor over many individual logic gate chips and circuit boards.

Author here, apologies for the dark mode issue and thanks for flagging it -- looks to be an open bug in theme-ui (https://github.com/system-ui/theme-ui/issues/1602).
I've just pushed a workaround that appears to have fixed it.
