Support for custom templates

[0x1eef]

I have created a simple custom template that adds my own stylesheet. It works locally, but not on rubydoc.info.
Should it work, and if not - can support be added?

Can you maybe share, in PR, what you've built so far?

I have made a few edits to the default template, and for now I'm carrying them around in each of my projects and hosting the contents on GitHub pages - since rubydoc.info is not including them.

Example is here:

I just realized some of those edits involve executing Ruby code so it is probably not practical to execute them on rubydoc.info.
