   One content element per viewport, big gaps, bilingual EN/DE,
   light/dark palette, scroll-aware chrome. Framework-free.
   Palette tokens live in CSS custom properties, switched via the
   data-palette attribute on .root; the background is additionally
   tinted by scroll progress in js/main.js.
