/*
  Pericope website. One column of text in the app's own colours and type.

  Colours come from App/Pericope/DesignSystem/Theme.swift. The one change is
  --ink-2 in light mode: the app's #7A7A80 is 4.27:1 on white, below WCAG AA
  for body text, so the site uses #66666C (5.70:1 on white, 5.19:1 on the tile).

  Poppins is the app's typeface. Copyright 2020 The Poppins Project Authors,
  licensed under the SIL Open Font License 1.1 (https://scripts.sil.org/OFL).
  The files in fonts/ are Latin subsets of the app's own font files, served
  from this site so no page loads anything from another website.
