For most of my project's documentation I prefer a standard sphinx layout. However for the landing page I would prefer to use custom HTML/CSS/JS without any of the layout, TOC, or sidebars of the normal sphinx site. Is there a way to include a raw HTML standalone page in a sphinx-generated website in a way that completely disregards the normal layout of the rest of the site?
As a counter example I know that I can include raw HTML bits into a page using the following (see also this question)
.. raw:: html
:file: myfile-html
However this just embeds a file within the normal layout. I would like to have a completely standalone HTML page.
