Original prompt

The instructions for this task are as follows:

Create a responsive, modern header for a personal developer portfolio site using HTML and CSS. Implement the following layout and styling:

Layout:

• Horizontal layout with left and right sections using Flexbox
• Left section: contains a compact symbol-only logo ("bw_") and the name "Brian Walker"
• Right section: contains external links to GitHub, LinkedIn, and Email

Design Requirements:

• Minimalist and clean, suitable for a dark-themed website
• Adequate spacing and visual breathing room between elements
• Logo and name aligned side-by-side with gap
• Social links are right-aligned and horizontally spaced
• Font should be modern, sans-serif, and readable
• Colors: white text on dark background (#0f0f0f); links can inherit color
• Hover effects on links (underline on hover, slight opacity by default)
• Add a subtle bottom border to the header

Responsiveness:

• On screens below 600px, stack the two sections vertically
• Maintain centered alignment and spacing on mobile

Bonus:

• The logo image should support transparent PNG or SVG
• Add basic accessibility: alt text for the logo, rel="noopener" on external links

Output the complete HTML and CSS. No JavaScript required.

The new CSS variables --bg-header and --border-header need to be defined for light mode as well. Currently, they will use dark mode values even when light mode is active. Add these variables to the body.light-mode selector (around line 32-39) with appropriate light theme values, such as:

--bg-header: #ffffff; --border-header: rgba(0, 0, 0, 0.1);
