First GH Pages deployment

So this is a big step towards a more inclusive presentation that doesn't necessarily depend on knowledge of a specific platform. The GitHub Pages interface also makes it easier to view and navigate file connections.

This (preview) version marks the first official export, and since there are already a considerable number of files created, something might still be a little off. Much of the export work is still manual, despite the wonderful Obsidian Webpage Export plugin developed by @KosmosisDire, which takes care of converting the files to enable the deployment of a static HTML page.

If you encounter any issues, don't hesitate to send a message or open an issue at programming-studies/issues.
