fix: reduce spacing between logo and company name

- Reduce logo width: 140px → 120px
- Reduce padding/margin: 20px → 16px
- Reduce font-size: 16px → 15px
- Reduce letter-spacing: 1px → 0.5px
- Use exact dimensions (width/height: 100%) instead of max
- Add white-space: nowrap to prevent text wrapping
- Lighter border color: #ddd → #e0e0e0

Result: Tighter, cleaner layout with less wasted space
