   A quiet doorway, not a sales page. Warm paper by day, deep ink by night,
   one accent of candlelight gold. The whole discipline of the type is air:
   wide margins, generous leading, a narrow reading measure, and long pauses
   of empty space that are not empty — they are room to exhale.

   Colours are the app's own tokens (DesignSystem/Theme.swift), verbatim.
