Many companies have these style guides around typography. Beautiful, thoughtful, very well made things for sure, yet when some backend dev makes a typo so the custom font drops to arial or whatever, it can be days before someone notices and the ones who notice are the font nerds from marketing. Nobody else seems to mind much.
Compare that with what happens if someone misunderstands the 20 year old SQL schema and writes the wrong magic string to a table. Instant crash, everybody notices immediately. Yet database schemas for internal applications tend not to be documented in Porsche-brochure-like sites like this Sweden Sans is.
How did the typography guys get a voice so strong? Note that I don't mind it, I like to see well made things in general, but it's puzzling. It's like there is a secret society of typography nerds that have spread to all major organisations.
>Might I also remind you, the point of the entire backend of an app is to serve the front end. An app with amazing backend practices but fails at matching designs or specs is just a failure and is noticeable by customers.
Just checked my notes and it turns out that frontend is just a temporary fashion-dictated skin over the actually important features of the backend! ;-)
