Starter post: proving the content path
Scaffolding content that proves a Git-backed MDX post can become a public page.
This is scaffolding content, not a finished article or a statement of the blog’s future visual identity.
The useful proof is deliberately small: this readable MDX file supplies the narrative, Astro turns it into a static public page, and one React island can add interaction without taking over the rest of the article.
Later writing can stay plain Markdown for as long as it needs to. Richer pieces can opt into approved components without changing the post’s route or moving the prose into application code.
