/* 
Resume-page Styling:

1. Typography: Clear, professional font stack is easy to read on screens and compatible with ATS systems.
2. Layout: Flexbox is used effectively for header and section layouts, ensuring content is well-aligned and spaced.
3. Color and Contrast: The color palette provides sufficient contrast between text and background, improving readability and accessibility.
4. Responsiveness: The media query adjusts layout for smaller screens, stacking elements and resizing images for mobile usability.
5. Whitespace and Margins: Generous padding and margins create a clean, uncluttered look that guides the reader’s eye naturally.
6. Interactivity: Smooth hover transitions on navigation links enhance user experience without distraction.
