Is there a way to have ConTeXt setup the pages this way? A simple \pagebreak command would send documents to the next "page" while still being on the same physical page when printed, and headers appear on top like normal. Cuttings lines aren't needed, as I can measure on a paper cutter to get the cuts right.

You could use ConTeXt's imposition mechanism.  The examples have to be typeset using context --arrange.

Let $L = sl_2(\mathbb{C})$. We call $L = H_0 \oplus H_1 \oplus H_2$
 an $orthogonal \ decomposition$ if  all components $H_i$ of decomposition are Cartan subalgebras and pairwise orthogonal with respect to the Killing form.
Now, suppose that $H_0$ is a Cartan subalgebra consisting of the diagonal matrices and $H_1$ is another Cartan subalgebra orthogonal to $H_0$ via the
