Technical Polish — Inter, KaTeX, and Prose Styling

Typography & Readability

I've swapped the primary UI font to Inter. This change improves compatibility with markdown parsing and ensures a cleaner, more professional look across different devices.

Mathematical Expressions

Integrated KaTeX support to allow for high-quality rendering of mathematical expressions within blog posts. This was achieved by importing the KaTeX CSS into the main stylesheet and ensuring the markdown parser correctly handles the syntax.

Prose Styling

• Heading Underlines: Added subtle underlines to headings to improve section separation.
• Code Blocks: Enhanced code block styling for better contrast and readability.
• UK Localization: Standardized on en-GB localization, including "licence" spelling and UK-specific date formatting for OG images.
• Copyright: Added a dynamic copyright year range that automatically updates based on the current year.
