Seline
A calm, privacy-first analytics SaaS interface built on a warm stone-gray canvas (#fafaf9) with white product cards, a single sky-blue accent, and lightweight Roobert display headlines paired with Inter body text. The system reads as quiet, engineered, and trustworthy — generous whitespace, soft 10px cards holding real product UI fragments (dashboards, funnels, journeys), pill-shaped controls everywhere, and a restrained green/red semantic palette borrowed from the analytics charts themselves.
