/* Cadence — cohort schedule.
   Identity: one session, two clocks. Rose is India's clock, periwinkle is
   yours, violet is the bridge — the same gradient runs through the wordmark,
   the primary button, and the ribbon that slopes between the two 24-hour
   tracks on every card. Two committed themes: a deep-space dark and a
   lavender-paper light. Ornament budget is spent on the hero ambience and
   the strip; everything else stays quiet and precise. */
