/* 
Contact-page Styling:

1. Base styles: Sets a clean font stack, neutral background, and readable text color.
2. Header: Flexbox aligns the logo dot, name, role, and navigation horizontally with spacing. Navigation links highlight in yellow on hover.
3. Main contact section: Flexbox layout with two columns — contact info and form. Form inputs and textarea are styled for usability and accessibility.
4. Buttons: Styled with distinct color and hover effect for user interaction.
5. Footer: Flexbox layout with spaced sections, grayscale social icons that colorize on hover, and responsive stacking on smaller screens.
6. Responsive design: Media query adjusts main content and footer layout for narrow viewports, stacking elements vertically and resizing images.
