/* The commercial site. Hand-written HTML on its own static hosting project, because the
   only thing it shares with the editor is a look — and the editor's build is 900 files of
   React to serve four paragraphs.

   The palette and the two faces are copied from the app's globals.css rather than imported:
   a second origin cannot read the first one's stylesheet, and a font served cross-origin
   needs CORS the app does not set. Three faces instead of six — this site has one heading
   and some running text. */
