The outer <code> here is simply a very poor choice due to what I can only imagine is ignorance. It would be better removed, and the `code` rule in the stylesheet changed to `body` and `font-family: monospace` added. (And `code code` would need to be changed to `code`.)

You could use <article /> instead (which I probably would). Jest tested it using dev tools, seems to work.

Using some HTML elements like section makes Safari switch to "reader" mode. Which is broken.
