   Spacing and layout utilities.

   These exist because the Content-Security-Policy sets `style-src 'self'
   'nonce-...'` with no 'unsafe-inline'. A nonce cannot apply to a style
   ATTRIBUTE, and style-src-attr falls back to style-src, so every
   `style="..."` in a template was being silently dropped by the browser and
   the spacing collapsed across half the admin. Weakening the policy to allow
   inline styles would have been the smaller diff; these classes are the
   smaller compromise.
