add a /blog/ path

[cldellow]

I'd like to write up some notes on things I've learned along the way to help out other folks, see https://github.com/hikeratlas/basemap/issues/9 for things I encountered while creating a basemap.

I imagine I'll encounter other things when doing an interactive webapp (eg: enumerating trails as complete trails, computing elevation profiles, client-side routing) and a native app (eg: expo vs native).

Can we graft a /blog/ route onto the site? Simpler is better.

I considered:

• deploy a Hugo blog to blog.hikeratlas.com, and accept that it's on a different domain
• deploy a Hugo blog to blog.hikeratlas.com, and do some CloudFlare Worker shenanigans to graft it on to hikeratlas.com
• use MDX support in Remix: https://remix.run/docs/en/main/guides/mdx

Let's try to get MDX support in Remix working. It should "just work", and allow interactive blog pages.

I was able to create /app/routes/blog/index.mdx and have it render at https://hikeratlas.com/blog/

When I tried to create /app/routes/blog/foo.mdx, it 404s at https://hikeratlas.com/blog/foo (and https://hikeratlas.com/blog/foo/)

Same thing if I create /app/routes/blog/foo/index.mdx, so I must be missing something. I hate magic when it doesn't work. :(

Using /app/routes/blog._index.mdx and /app/routes/blog.mapping-overview.mdx seems to work. (/app/routes/blog/_index.mdx and /app/routes/blog/mapping-overview.mdx does not work.)

I don't understand it, I don't like it, but it works, so good enough for now.
