/*
  Shared styles for the Zebal guide pages.

  Kept in one file rather than repeated inside each page, so a change to
  spacing or colour applies everywhere at once.

  Colours mirror the app's own palette, and every text/background pair meets
  the WCAG AA contrast minimum of 4.5:1 — the same standard the app was built
  to. Sizes use rem so the browser's own text-size setting keeps working.
