Theme Test

A compact proof page for prose, margin notes, figures, disclosures, and article-local scripts.

A generated technical texture used as a placeholder hero.

This page is intentionally plain: it exists to verify the article geometry before the first real essay exists. The base page stays quiet, while article-owned CSS and JavaScript load only because this bundle asks for them.

Margin notes are for definitions, context, and small reading guides. They become tap-to-open notes on narrow screens.

The main column has a disciplined measure and an actual margin column. Sidenotes stay near the text they explain. The first version uses a no-JavaScript checkbox pattern for mobile sidenotes.

Figures

Markdown images are routed through the render hook, while figures use the page bundle directly.

Optional depth

Implementation notes
This disclosure uses native HTML. Use it for optional derivations or implementation detail, not for steps the main argument depends on.

Article-local interactivity

The canvas below is initialized by interactive.js, which belongs to this article bundle and is loaded only on this page.
