This commit introduces three new documentation files: `anwendungen.md` for AI solution use cases, `stylesheets/modules/blog.scss` for blog-specific styling, and `datenschutz.md` for the privacy policy. Additionally, it enhances blog author and sidebar styling for consistency and readability.
Reorganized font and image assets, replacing outdated files with new ones. Removed unused SVG icons and updated the sitemap with new URLs and last modified dates. Simplified font-face declarations to reflect the updated font structure.
