Unfortunately it won't display without JavaScripts. You can easily fix this by a <noscript> block with the link to the Markdown file; if it is not possible, instead include a description about how to find the Markdown file.

Another alternative that I would suggest is to just serve the files directly (in Markdown or Gemini or PDF or whatever other format they might be). To allow working in a web browser, one idea is to try to implement my idea of a Interpreter response header in web browser, which would be used if the web browser does not understand the file format (if the user has not disabled the use of the Interpreter header). This way, potentially any file format can be implemented.

There is also question about different variants of Markdown. Well, the way to indicate that is by parameters in the MIME type, I think; you can specify if it is Commonmark or something else. This way you can tell which variant it is.

One problem with MIME is that indicating multiple file formats does not work very well. UTI specifies that it is a specific kind of another file format but it must be specified in another file instead of this one and does not have parameters, and has other problems, so UTI is not good either. That is why I wanted to make the "unordered labels file identification" which you can specify, in the same identification, multiple types/parameters, e.g. "text[367]:plaintext:markdown+commonmark".
