/* ProvenExit. One brand accent (violet, --accent) carries the page: labels, links, lines, icons, focus
   and tinted grounds. Green and red are evidence: those tokens are used only in the last block of this
   file, under html[data-state="verified"] or html[data-state="refused"], which app.js sets from the
   current status response. The accent never stands for a verdict. */
