Phase 2 of i18n rollout:
- All 54 static custom sites now have data-de/data-en attributes on
visible text elements with English translations
- i18n.js script tag injected into all sites
- Language toggle button with machine-translation disclaimer added
to every site's footer area
- Brand names / domain wordplay preserved unchanged in both languages
- 2 dynamic sites (dasbes.de, dumusst.com) skipped — no static HTML
