GPT docs pages go live

The documentation pages for joynt.co.uk GPTs are now live. The site is using the Minimal Mistakes theme.

This is a slightly more involved theme than the minima one used in the dev.joynt.co.uk site, but the benefit is a much more attractive and engaging layout.

Features used in this site include:

• Images, especially on the “splash page”
• Permalinks for pages, esp. for GPT pages, e.g. /arcane_paintbrush/
• New category and tag pages for posts.
