ATMOS. Violet horizon above white void.

Atmos is a single-screen meditation: one deep violet sky fading to lavender above an expanse of white silence. The entire interface lives in the first viewport — a colossal serif wordmark, a ring of small caps text orbiting it, and a single pill button — then dissolves into negative space. Typography does the heavy lifting: a custom display serif at 200px whispers rather than shouts, paired with DM Sans for micro-labels. There is no product UI, no navigation bar, no cards, no shadows. The only chromatic note is the violet gradient; everything else is paper-white and ink-black.
