/* Landing page (Brief 17 → 19, D-068/D-069/D-070): the shell (header, footer, buttons, logo, fonts) is css/site.css; the approved variant 11 – the poster language of 09 Plakat with the
   scenario wall of 04 Leitwarte. All colours are tokens from feldmelder.css (:root, --lp-*); no Tabler on this page.
   Boldonse (statements) and Work Sans (text), self-hosted, SIL OFL 1.1; loaded with font-display: block and preloaded,
   because a fallback swap of Boldonse reflows the whole poster. Concept and decisions: docs/design/variants/v11.md. */
