WHY IT WORKS
Structure meets readability

Karla is a grotesque with a little quirk in its forms, giving the body more personality than a pure neutral while still reading cleanly under Roboto Slab's confident slab headings.

Where it shines

Design-led and indie product sites wanting a sturdy heading over a body with some character.

Where to be careful

Karla's character competes slightly — keep it to body and small UI, not headings.
