/*
  prose.css -- reading typography for Portable Text bodies. Wrap rendered
  content in an element with class="prose".

  These rules sit in @layer base, so overrides in theme.css win without
  specificity tricks. The variables at the top theme EmDash's built-in
  block components (images, pullquotes, buttons, files, tables) to match.
  The exception is the short unlayered block at the end, which needs
  !important to restyle EmDash's code, button, and file blocks; override
  those properties with !important too.
