Most of the uses of monospace font within the openbmc web interface are presenting very "terminal-like" data. The Courier family is good because it is universal, but it isn't considered a great font for terminal work because it can be difficult to read compared to other fonts. Can we explore a more modern font, such as the Menlo / DejuVu / Bitstream Vera Sans Mono family? While none of them are universal on their own, I think if you specify all 3 you'll get coverage on MacOS / Windows / Linux respectively (and all 3 are nearly identical fonts).
