/*
  Zepworks site styles, layered over the Hextra theme.

  Idea: the diff is the signature. The homepage headline is a diff hunk, and the
  removed/added colors appear only where something actually changed (the hero,
  the wordmark glyph, `diff` code blocks). Everything else is ink on paper.

  Hextra's utility classes live in a CSS layer, so these unlayered rules win
  without !important. Its typography rules use :where(), so one class beats them.
