+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Bind the existing footer into the landing page and add real Impressum and Datenschutz routes so the legal links resolve correctly.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Landing page renders the footer component below the main landing content
+- [x] #2 Footer links point to /impressum and /datenschutz
+- [x] #3 /impressum contains the provided business and VAT ID information
+- [x] #4 /datenschutz states that no cookies are used and documents the current Rybbit analytics usage
+- [x] #5 Automated content tests and Astro build pass
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add failing content tests for footer rendering and legal pages
+2. Implement footer wiring and legal Astro pages
+3. Run automated tests and build
+4. Check off verified acceptance criteria and leave task In Progress for user confirmation
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Implemented footer rendering on the landing page and added /impressum plus /datenschutz Astro routes.
+
+Verified with node --test tests/*.mjs and env CI=true pnpm build. The first sandboxed build attempt failed because pnpm needed network access to recreate node_modules; the escalated build completed successfully.
+
+Task remains In Progress pending explicit user confirmation before moving to Done.
+
+Adjusted footer per visual feedback: removed the CTA/contact block and kept only the compact copyright, analytics note, Impressum, and Datenschutz row. Footer now uses the same horizontal page padding as the landing sections instead of max-w-6xl centering.
+
+Re-verified after the footer adjustment with node --test tests/*.mjs and env CI=true pnpm build.
