+# Responsive Footer Name & Legal Contact Links
+
+**Run ID:** d7e7bdf6
+**Date:** 2026-02-07
+**Specification:** agentic/specs/260207-footer-responsive-hide-name-add-contact-links.md
+
+## Overview
+
+The footer's "markus neusinger" link is hidden on mobile viewports (below 960px / `md` breakpoint) to prevent a cramped layout, and social contact links (LinkedIn, X, GitHub) were added to the Legal Notice page's Contact section to keep contact information discoverable.
+
+## What Was Built
+
+- Responsive hiding of the "markus neusinger" link and its dot separators in the footer on screens below the `md` breakpoint (960px)
+- LinkedIn, X (Twitter), and GitHub contact links added to the Legal Notice page Contact section with analytics tracking
+
+## Technical Implementation
+
+### Files Modified
+
+- `app/src/components/Footer.tsx`: Wrapped the "markus neusinger" link and its surrounding dot separators in a `<Box>` with responsive `display` (`{ xs: 'none', md: 'contents' }`) to hide them on mobile
+- `app/src/pages/LegalPage.tsx`: Added three social links (LinkedIn, X, GitHub) to the Contact section below the existing email link, each with `target="_blank"`, `rel="noopener noreferrer"`, matching `#3776AB` color styling, and `trackEvent` analytics calls
+
+### Key Changes
+
+- Used MUI's responsive `sx` display prop for pure CSS-based hiding — no JavaScript media query hooks needed
+- The `<Box component="span" sx={{ display: { xs: 'none', md: 'contents' } }}>` wrapper ensures the name link and both adjacent dot separators are hidden/shown together, and `contents` on desktop means the Box has no visual impact
+- Social links in the Legal page follow the existing pattern: `<br />` line breaks within the `<Typography>` block, consistent `#3776AB` link color
+- Analytics tracking uses `trackEvent('external_link', { destination: 'linkedin' | 'x' | 'github_personal' })` matching the existing event pattern
+
+## How to Use
+
+1. On mobile devices or viewports narrower than 960px, the footer displays: `github · stats · mcp · legal`
+2. On desktop viewports (960px and wider), the footer displays the full set: `github · stats · markus neusinger · mcp · legal`
+3. Social contact links are always visible on the Legal Notice page (`/legal`) in the Contact section
+
+## Configuration
+
+No configuration needed. The `md` breakpoint (960px) is defined by the MUI theme and matches the FilterBar's mobile breakpoint.
+
+## Testing
+
+- `cd app && npx tsc --noEmit` — Verify TypeScript types
+- `cd app && yarn build` — Verify no compilation errors
+- Resize browser below/above 960px to confirm the footer name link hides/shows
+- Visit `/legal` and verify LinkedIn, X, and GitHub links appear in the Contact section
+
+## Notes
+
+- The 960px breakpoint was chosen to match where the FilterBar catalog/filter row wraps to 2 lines on the homepage
+- The LinkedIn URL in the footer and Legal page are intentionally the same — redundancy ensures discoverability
+- The `github_personal` destination in analytics distinguishes the personal GitHub profile link from the project repository link

+# Feature: Responsive Footer Name & Legal Contact Links
+
+## Metadata
+
+run_id: `d7e7bdf6`
+prompt: `im footer mein name markus neusinger ist recht lang bei kleinen bildschrimen mobile... sieht das nichtmehr gut, minimal aus, ich möchte das ab der grösse bei der auch auf der startseite die filter zeile mit catolog... steht in 2 zeilen übergeht das mein name nichtmehr im footer zu sehen ist, dafür soll aber im legal tab bei contact links zu meinem linkedin x und github account sein zusätlich zu der email die schon da steht https://x.com/MarkusNeusinger https://github.com/MarkusNeusinger https://www.linkedin.com/in/markus-neusinger/`
+
+## Feature Description
+
+Two related changes to improve the mobile experience:
+
+1. **Footer**: Hide the "markus neusinger" link on small screens (below `md` / 960px breakpoint) — the same breakpoint where the FilterBar catalog/filter row wraps to 2 lines on the homepage. The name is too long and makes the footer look cramped on mobile. The dot separator before/after the name link should also be hidden.
+
+2. **Legal Page**: Add social/contact links (LinkedIn, X/Twitter, GitHub) to the Contact section in the Legal Notice, alongside the existing email. This ensures the contact information remains discoverable even when the footer name link is hidden on mobile.
+
+## Requirements
+
+- Hide the "markus neusinger" link (and its surrounding dot separators) in the footer when viewport width is below `md` (960px) — matching the FilterBar's `isMobile` breakpoint
+- On viewports `md` and above (960px+), the footer remains unchanged
+- Add LinkedIn, X (Twitter), and GitHub links to the Contact section of the Legal Notice on LegalPage
+- Social links: LinkedIn (`https://www.linkedin.com/in/markus-neusinger/`), X (`https://x.com/MarkusNeusinger`), GitHub (`https://github.com/MarkusNeusinger`)
+- Maintain consistent styling with existing Legal Page link patterns (color `#3776AB`, monospace font)
+- Track social link clicks via existing analytics (`onTrackEvent` / `trackEvent`)
+
+## Relevant Files
+
+### Existing Files to Modify
+
+- **`app/src/components/Footer.tsx`** — Hide the "markus neusinger" `<Link>` and its adjacent dot `<span>` separators on screens below `md` breakpoint using MUI's `sx` display responsive prop
+- **`app/src/pages/LegalPage.tsx`** — Add LinkedIn, X, and GitHub links to the Contact section (lines 102-109) in the Legal Notice Paper, below the existing email link
+
+### New Files to Create
+
+None.
+
+## Implementation Plan
+
+IMPORTANT: Execute every step in order, top to bottom.
+
+### 1. Update Footer to hide name on mobile
+
+In `app/src/components/Footer.tsx`:
+
+- Add `useMediaQuery` and `useTheme` imports from MUI
+- Add `const theme = useTheme()` and `const isMobile = useMediaQuery(theme.breakpoints.down('md'))` inside the component
+- Wrap the "markus neusinger" `<Link>` (lines 54-66) and the `<span>·</span>` separator immediately **before** it (line 53) in a `<Box>` (or use `sx={{ display: { xs: 'none', md: 'contents' } }}`) to hide them on small screens
+- The simplest approach: use MUI's responsive `display` prop on the separator span and the link:
+  - On the `<span>·</span>` at line 53: add `sx={{ display: { xs: 'none', md: 'inline' } }}`
+  - On the `<Link>` for "markus neusinger": add `display: { xs: 'none', md: 'inline' }` to its `sx` prop
+- This leaves the remaining 4 links (github · stats · mcp · legal) visible on mobile, with proper dot separation
+
+### 2. Add social/contact links to Legal Page
+
+In `app/src/pages/LegalPage.tsx`:
+
+- Locate the Contact section inside the Legal Notice Paper (around lines 102-109)
+- After the existing email link `<Link>`, add three more links on separate lines:
+  - LinkedIn: `https://www.linkedin.com/in/markus-neusinger/`
+  - X: `https://x.com/MarkusNeusinger`
+  - GitHub: `https://github.com/MarkusNeusinger`
+- Use the same styling pattern as the email link (`sx={{ color: '#3776AB' }}`)
+- Add `target="_blank"` and `rel="noopener noreferrer"` for external links
+- Add `onClick` analytics tracking with `trackEvent('external_link', { destination: 'linkedin' })` etc.
+- Structure: keep it as a simple list within the existing `<Typography sx={textStyle}>` block using `<br />` for line breaks (matching the existing pattern in the Contact section)
+
+### 3. Verify responsive behavior
+
+- Build the frontend to ensure no TypeScript/compilation errors
+- Verify the footer shows 4 links on mobile (<960px) and 5 links on desktop (>=960px)
+- Verify the Legal page Contact section shows email + 3 social links
+
+### 4. Add Tests
+
+- No frontend test files exist in the project currently — skip test creation as there is no test infrastructure for React components
+
+## Validation Commands
+
+Execute these commands to validate the feature:
+
+- `cd app && npx tsc --noEmit` - Check TypeScript types
+- `cd app && yarn build` - Build frontend to verify no compilation errors
+
+## Notes
+
+- The `md` breakpoint (960px) was chosen because the user specifically asked for the same breakpoint where the FilterBar wraps to 2 lines, and `FilterBar.tsx` uses `theme.breakpoints.down('md')` for its `isMobile` check
+- Using MUI responsive `display` (`{ xs: 'none', md: 'inline' }`) is the lightest-weight approach — no JS needed, pure CSS media queries via MUI's system
+- The existing LinkedIn link in the footer (`markus neusinger`) already points to the same URL that will be added to the Legal page — this is intentional redundancy for discoverability
+- The GitHub link uses `GITHUB_URL` constant already imported in LegalPage for the Source Code section; the personal GitHub URL (`https://github.com/MarkusNeusinger`) is different from the project repo URL
