// Mirrors cantaricrestine-scraper.mjs. The Node scraper is the workhorse for the
// full catalog + PowerPoint files; this userscript is for quick, in-browser
// exports: pick a book (or "Toate") and download a TopPresenter Songs bundle that
// imports in one go. PowerPoints aren't downloaded here (use the .mjs) — their
// URLs are preserved in each song's `_extensions.cantaricrestine.pptUrl`.
