 ## [Unreleased]
 
 ### Fixed
+- i18n: improve German nav labels — "Verzeichnis" → "Anbieterverzeichnis", "Planer" → "Kostenrechner"
 - CI: add missing env vars to `.env` heredoc — `WAITLIST_MODE`, `LEADS_EMAIL`, `UMAMI_API_URL`; make Paddle vars optional (`:-`) so they don't break deploys when unset
