   DialogueScan: site styles
   Sister site to jpgrolle.com. Layout, spacing, buttons, header and
   footer mirror jpgrolle.com; colors and display type come from the
   brand brief in /brand (JP_Grolle_-_Brand.dotx). Body text is Inter,
   not the template's Source Serif 4: sans reads better on phones and
   matches jpgrolle.com. The serif stays in the Word reports.
   Rule of thumb: every selector is declared once. If a change doesn't
   take effect, look for a more specific selector, not a duplicate.
