Explainer packs
Print-ready bundles of system cards — every input, output, component and failure mode for a whole subject on one sheet.
A pack is every system card in a subject, laid out to print. Inputs, outputs, the parts that do the work, and how each one breaks — the reference half of the explainers, without the prose. Open one and print it, or save it as a PDF from your browser.
