Visual Theme & Atmosphere

Clean, commerce-confident design built for merchants: a white canvas with near-black text and the bold Square blue as the interactive accent. The signature device is a large forest-green rounded feature block (24px radius, white text) holding photos of Square hardware or checkout screens. Type is Square's own humanist sans at regular weight — size, not weight, makes the hierarchy — with pill CTAs and soft 16–24px rounded cards. Elevation is mostly flat, with separation via white / gray-50 / forest-green blocks rather than shadows; nothing flashy — confidence over spectacle. Feels: trustworthy, practical, friendly-professional.

Patterns: body 16–18px / 400 / #1a1a1a. Display is REGULAR weight (400) — Square uses size, not weight, for hierarchy; tracking near-neutral, slight negative tracking only on the biggest size. Headlines are never bold; buttons step up to 500. Calm, legible, commerce-friendly.
