/*
  Pottles — pottles.app

  The tokens are the app's own (DesignSystem/PottleColor.swift), including its one
  rule that matters most here: the page behind a character is always white. Cream is
  for things that sit ON the page — bubbles, the promise panel — never for the page.

  The apricot dot means what it means in the app: a plant has something to say.
  It never pushes, so it never pulses.

  The type is the app's too. `ui-rounded` is SF Rounded on the iPhones and Macs this
  app is for; Nunito stands in everywhere else.
