## C4: Mobile Spacing/White Gaps Cleanup ✅

**Acceptance Criteria**: No horizontal scroll, proper spacing on mobile

**Root Causes Fixed**:
1. **Nav-links overflow**: Desktop navigation (300px) extending beyond viewport
   - Fix: `display: none` by default, `display: flex` when active

2. **Section overflow**: Sections not respecting viewport bounds
   - Fix: Added `max-width: 100vw` and `overflow-x: hidden` to all sections

3. **Install command overflow**: Long command text extending beyond viewport
   - Fix: Added `overflow-wrap`, `white-space: pre-wrap`, font size reduction

**Evidence**:
- Homepage body scrollWidth: 393px (matches 390px viewport) - **0px overflow** ✅
- /explore page: 0px overflow ✅
- All mobile viewport tests passing (T3)
- Test evidence: debug-overflow.spec.ts confirms 0px overflow

**Commits**:
