   - notification rule custom subjects and bodies in DE/EN
   - welcome email subject and body in DE/EN
   - request language capture on onboarding/offboarding to choose the correct email language
+- Language stability hardening is in place:

+  - both request tables now have a database default of `de`
 - Several generated PDF business text blocks are still not fully bilingual yet.
 - CI now validates that translation catalogs compile successfully on push and pull request.

       <li><strong>Phase 2 added:</strong> dynamic Form Builder option labels, field label/help-text overrides, and intro-builder checklist item labels now support German and English values.</li>
       <li><strong>Email phase added:</strong> admin-managed notification template subject/body content, notification rule custom subject/body content, and welcome email subject/body content now support explicit DE/EN values.</li>
       <li><strong>Runtime selection:</strong> onboarding and offboarding requests store the UI language at submission time, and notification delivery uses that language with German fallback.</li>

       <li><strong>Not fully bilingual yet:</strong> several generated PDF/business text blocks still remain primarily single-language.</li>
       <li><strong>Implementation:</strong> Django i18n with locale middleware, translation catalogs, and a DE/EN language switch in the main UI.</li>
