Refine border styling for cleaner appearance

- Remove unwanted white border around footer while keeping top border line
- Make banner accent line thinner (1px instead of 4px) for more subtle appearance
- Improve overall visual hierarchy and clean up border inconsistencies

These refinements create a more polished and professional look while maintaining the visual separation elements that enhance the design structure.
