Check out static site generator. I’ve specifically used Hugo which took markdown files as input/content, but there are many options.

They are also really easy to host on a git forge.

I know this don’t the solution you are looking for, but your router sounds like the crappy default one you get from your ISP.

In that case (since you already got this far) consider getting a better one, if not for this, then for the next time it limits your adventures.

I would suggest looking into OpenWrt if you go this route.

If you go the film route, consider using 8mm. Even though some people thinks it’s still too experimental i find the file compression to be far superior (one third file size after transcoding my library from VHS -> 8mm film) and they barely burst into flames.

Besides who has movie nights without drinks nearby you can put on the fire?

Make sure you use mixed drinks and not hard liquor as that will not put out fire and make your insurance company really annoying.
