Test module

This module exists to show off the whole content system in one place — so you can click through it and see what every feature looks like.

The sidebar on the left mirrors the folder structure exactly:

• a loose page sitting straight under the module (no chapter),
• numbered chapters (1, 2, 3),
• pages inside them (1.1, 1.2, …),
• a sub-folder nested inside a chapter (2.2.1),
• and a deliberately unnumbered, long-titled page to show wrapping.

Open each one to see Markdown, math, images, an interactive visual, and fold-out answers in action.
