# amp — Style Reference
> warm orange pill on cool white. The design feels like a premium fitness product photographed in a sunlit loft: one object, one accent, one confident typeface doing all the work.

amp is a single-color, single-typeface system: one warm orange against an achromatic canvas, and one custom sans-serif used at every size. The page reads like a product photography spread — generous whitespace, large editorial headlines, and a single device (the amp column) photographed in a soft beige interior. Orange is rationed: it marks the buy button, the current step indicator, and a thin accent rule. Everything else stays in white, off-white, and near-black, so the accent does the talking. Cards and inputs use small 5px corners; the primary CTA is a 50px pill with a brand-colored glow; secondary controls round to 24px. Typography is one family (PublicaSans) at weights 300/400/500, tightening its tracking aggressively as sizes scale up — -0.036em at display, almost zero at body.
