===============

This page exists to prove a point: with Sphinx, pages don't “randomly disappear”
as long as they are linked in a ``toctree``.

------------

* **Source files**: reStructuredText (``.rst``)
* **Navigation**: explicit ``toctree`` blocks (no magic)
* **Build**: ``sphinx-build -b html docs docs/_build/html``
