This post exercises every feature and formatting element the blog supports. Use it to verify rendering after changes, and as the reference for the canonical post style. The headings below also demonstrate the fixed heading scale.

Heading Level 2 (section)

Top-level post sections use ##. Body text is justified, monospace, and wraps normally. This sentence exists to show how a longer paragraph flows across the column so that justification, line-height, and wrapping can be eyeballed at a glance without hunting through a real post.

Heading Level 3 (subsection)

Subsections use ###.

Heading Level 4 (minor)

Minor points use ####. Avoid going deeper than h4.

Inline Elements

Regular, bold, italic, strikethrough, inline code, a link, and a keyboard key like Ctrl + C. A footnote reference sits here.1

GitHub-style Alerts

[!NOTE] Useful information the reader should notice even when skimming.

[!TIP] A helpful suggestion for doing things better.

[!IMPORTANT] Key information the reader needs to know to achieve their goal.

[!WARNING] Urgent info that needs immediate reader attention to avoid problems.

[!CAUTION] Advises about risks or negative outcomes of certain actions.

A plain blockquote, for contrast:

Code Blocks

Fenced blocks get a language label and a copy button automatically. Add an optional filename with a first-line filename: comment (it shows in the bar and is stripped from the copied text). ASCII diagrams (text/ascii) show no label.

# enumerate listening sockets
ss -tlnp | grep -i sshd

// filename: loader.c
void load_file(char *name) {
    char path[100];
    snprintf(path, sizeof(path), "/var/data/%s", name);  // bounded
}

def reward(mitigated, fp, dt):
    return 1.0 * mitigated - 0.5 * fp - 0.1 * dt

Inline code stays unstyled by the bar.

Math

Inline math such as $E = mc^2$ and $\pi^* = \arg\max_\pi V(\pi)$ renders inline. Display math:

\[R_t = \alpha \cdot \mathbb{1}_{\text{hit}} - \beta \cdot \mathbb{1}_{\text{fp}} - \delta \cdot \Delta t\]
