/*
  Moch — site stylesheet
  World: the Mocheme theme the app ships today. Near-black indigo surfaces
  (#0A0813, hue ~249°), one saturated accent — Moch's antenna orange #F79236 —
  reserved for action, cream #F6ECE1 for the user's own words (the app's user
  bubble), and Moch the mascot as the friendly face. Bricolage Grotesque
  display voice over Hanken Grotesk body; the miniature phone UI uses the
  app's own vocabulary: cream bubbles, dashed thinking pill, gradient send.
