    But new request "Deep blue and clean white color scheme".
    Usually Deep Blue themes have Dark Footers.
    I will stick to the Deep Blue Theme variables which define Footer as Deep BG ?? 
    Wait, in my CSS I defined: --tech-deep-bg: #0f172a; 
    Let's check the previous plan. "Footer: Lighten the background".
    However, the latest prompt "High-High-End UI... Deep blue and clean white".
    A white footer is safer for "Lighten the background".
    I will make the footer LIGHT in CSS to respect the earlier specific feedback.
