This post sets toc: true and comments: true in its front matter.

Search is fully client-side (elasticlunr). The index is built at load time from posts and every output collection, so this post is searchable from the search overlay.

Math

Inline math like $a^2 + b^2 = c^2$ and display math render via KaTeX:

\[\int_0^1 x^2 \, dx = \tfrac{1}{3}\]

Comments

Because comments: true is set, a comments section appears below. Giscus only loads when you configure giscus.* in _config.yml; otherwise the section is empty by design.
