Hello, world — welcome to the playground

This post is hand-authored placeholder content. When the Slate snippet connects to a real site, it'll fetch the matching post by slug and swap this content out with whatever's in the CMS.

How the swap works

The snippet loads a small manifest — a list of every published slug on the site — and compares it against window.location.pathname. If there's a match, it fetches the full content as JSON blocks and renders them into the page's <main> element.

The static HTML is the shell. The CMS is the voice. Separate concerns, same page.

What to try

• Create a post in the Slate app with slug /blog/hello-world and reload this page — your content should replace this placeholder.
• Edit the title and meta description in Slate — watch the browser tab and og: tags update.
• Publish a post at a slug that has no matching HTML file — the snippet will rebuild the page from the cached header and footer.

This file lives at blog/hello-world.html in the repo. Feel free to edit it locally and push — the static version is what visitors see until the Slate snippet kicks in.
