Colophon.

This is the first entry in the notebook. The pipeline works:

• Astro 5 Content Collections
• Markdown files in src/content/posts/
• Each file becomes /notebook/<slug>
• A frontmatter date field switches a post from forthcoming to published

Writing flow

1. Create a new .md file under src/content/posts/
2. Fill in title and summary in the frontmatter
3. Write the body in Markdown
4. Add date: 2026-06-14 when ready to publish
5. git push — Cloudflare Pages builds and deploys

What renders

Standard Markdown: headings, lists, links, inline code, code blocks, blockquotes, tables.

// Code blocks use Shiki by default
const posts = await getCollection("posts");

Blockquotes look like this. Useful for citing sources.

Delete this entry whenever the first real post is up.
