A first post
This is a placeholder. Delete it, or edit it into something real — the file
lives at _posts/2026-09-05-a-first-post.md and the whole post is just
markdown under three lines of front matter.
The filename sets both the date and the URL. 2026-09-05-a-first-post.md
becomes /writing/a-first-post/, dated 5 September 2026. Nothing else needs
configuring.
