Markdown Sandbox

This post exists to verify the first version of the blog stack. It should render cleanly, stay readable, and cover the Markdown features we care about most.

What should work

headings and body copy
links like GitHub Pages
blockquotes
code blocks
tables
Mermaid diagrams
inline math like $E = mc^2$
display math

Good defaults matter. They remove friction from publishing.

Table

Feature	Status	Notes
Tables	Ready	Standard Markdown tables render without extra work.
Mermaid	Ready	Rendered progressively on the client only when needed.
Math	Ready	KaTeX renders on the client after the page loads.
Drafts	Ready	Hidden from production, visible in development.

Mermaid

Math

When a model predicts outcomes with a linear hypothesis, we often write:

$$ \hat{y} = \beta_0 + \beta_1 x_1 + \beta_2 x_2 $$

And a simple loss term can be written as:

$$ L(\theta) = \frac{1}{n} \sum_{i=1}^{n}(y_i - \hat{y_i})^2 $$

Code

const publish = async (post) => {
  const status = post.draft ? "preview" : "production";
  return `${post.title} -> ${status}`;
};

Closing note

If this page looks correct on the final site, the first version of the content pipeline is in good shape.
