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
- shared/impressum.js: configurable via data-owner and data-style attrs
- Default: minimal msbls.de attribution for satire sites
- Build now copies shared/ to build output
- Caddyfile serves /shared/* globally across all domains
- Removed martinsiebels.de references from 7 KI-satire sites
