   FAHRSCHULPORTAL: DIE TEXTSEITEN
   (/datenschutz, /impressum, /nutzungsbedingungen, /konto-loeschen, und
   die Artikel unter /hilfe, die dasselbe Lese-Layout nutzen)
   ==========================================================================

   After /styles.css, /brand.css and /landing.css: header, footer, buttons
   and icons are the landing page's (src/lib/site-shell.js renders the
   frame). This file is the page between them:

     .pg-hero     crumbs, title, stand, the tabs between the legal pages —
                  over the landing page's ruled paper and a soft light;
     .pg-layout   a reading column and, beside it, a table of contents that
                  stays in view and marks where you are (js/pages.js);
     .lp          the text itself: a reading measure, clear section heads
                  with their number, links that look like links.

   Long text, so motion is limited to the page arriving and the contents
   following the reader. Prefix `pg-` (page), `lp-` kept for the building
   blocks the fragments under src/views/legal/ already use.
