Seline Analytics. Quiet analyst's desk on warm paper.

Seline sits on a warm-stone canvas (#fafaf9) with a single vivid cyan as its only chromatic accent — every other color is a neutral pulled from the Tailwind stone scale. Headlines use a custom geometric sans (roobert) at weight 400 with tight negative tracking, giving display copy an unhurried, almost whispered authority that contrasts with the usual SaaS shout. UI surfaces are flat white cards floating over the warm background via a single soft 16px-blur shadow; borders are 1px stone hairlines used generously as the primary structural device instead of heavy dividers or panels. The layout breathes: max-width content centered on generous vertical rhythm, with pill-shaped interactive controls, a mascot sticker illustration for personality, and data dashboard screenshots as proof-of-product. The overall feel is editorial analytics — calm, monochrome, confident — where the blue CTA is the loudest thing on the page by deliberate restraint of everything else.
