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.
Introduced mobile and medium responsiveness in stylesheets for better layout on smaller screens. Adjusted FAQ script to properly remove duplicate event listeners and ensure functionality remains smooth on initialization.
