Zipped print-ready PDFs — student packet, substitute guide, and answer key for each packet.
Machine-readable catalog: catalog.json · catalog.csv.
Regenerate every PDF, preview, ZIP, and the catalog with ./build.sh.
Every packet follows the same routine so students recognize it even when the subject changes: Start → Build → Apply → Explain → ACE close → (optional) Continue. The substitute guide is readable in five minutes and needs no subject expertise; the answer key is always a separate file so it is never copied for students. Everything prints clearly in grayscale and reflows as accessible HTML.
