/* The modal and the fields inside it - the one stylesheet a dialog needs,
   loaded by BOTH layouts. It lived in site.css until the Submit Feedback
   dialog was found unstyled under the footer of every ported page (UAT
   A8): the legacy layout loads legacy/styles.css and never site.css, so
   the overlay had no rules at all there.

   Every rule is scoped to .po-modal, because on a legacy page the vendor's
   element rules are already in force - label is small caps with a margin,
   h2 is 2.25rem, input fills its width in Open Sans, and button and
   .button carry their own padding and border. A rule here either sets
   what it needs outright or out-specifies the vendor's, so the dialog
   looks the same on both layouts. Reads tokens.css for every value */
