WHY IT WORKS
Structure meets readability

Source Sans is a humanist sans, so against Poppins's geometric construction there's genuine structural contrast: Poppins leads with geometric confidence, Source Sans recedes as calm, neutral, readable text. That humanist-versus-geometric difference keeps an all-sans system from looking like two similar fonts placed together by mistake.

Where it shines

Tech, corporate and app marketing that wants a clean, uncluttered sans-only system.

Where to be careful

Keep headings at Poppins 600+ and body at Source Sans 400 so the roles stay clearly separated.
