A small kit of the type, colour, and ground rules we use across the site. Borrow what you need. One ask: don't make it look generic.
Use the wordmark as-is. Don't recolour it (apart from the two approved variants below), don't reset the spacing, and please leave the “code” roundel where it sits — that loop is the brand.
Mostly paper, ink, and a single confident teal. Keep accents sparing — they're loudest when they're rare.
Serif for headlines, sans for everything you actually read, mono for labels and small print. Default fonts are off-limits — if you can't load one of these, fall back to system serif/sans/mono in that order.
