This page exists solely as a fixture for Tapestry's automated test suite. It exercises every markdown construct and custom shortcode the theme supports, so a single visual/accessibility pass over this one page (per style/variant/mode) covers the single-article template's feature surface without depending on the site's real demo content.

KaTeX math

Inline math: $\KaTeX$ renders $(i\gamma^\mu \partial_\mu - m)\psi = 0$ right in the sentence.

Display math (Schrödinger equation):

$$ \displaystyle i\hbar \frac{\partial}{\partial t} \Psi(\mathbf{r}, t) = \left[ -\frac{\hbar^2}{2m} \nabla^2 + V(\mathbf{r}, t) \right] \Psi(\mathbf{r}, t) $$
