Notation

The last two chapters were calculus. This one is not. I am writing every shape I expect the site to survive: stacked and aligned systems, matrices and cases, ordinary and partial differential equations, integrals on curves and volumes, accents, fonts, limits, series, and transforms. If a construction is missing here, it is missing from the pipeline.

The files below are the gauntlet. They are still first-person notes. They are also a test.
