// make-tiny-pptx.mjs
//
// Builds a minimal ECMA-376 (OOXML) presentation skeleton and writes it to
// tests/fixtures/documents/tiny.pptx using adm-zip (root devDep).
//
// ACCEPTANCE (2026-06-12, snapotter/snapotter:latest + libreoffice-impress):
//   soffice --headless --norestore --nolockcheck --nodefault \
//     --convert-to pdf --outdir /tmp /tmp/tiny.pptx
//   Result: /tmp/tiny.pdf produced, 8454 bytes. Impress opens the skeleton
//   and renders the single-slide text box via impress_pdf_Export filter.
//   NOTE: libreoffice-impress must be added to the Dockerfile (wave 3b image
//   only had libreoffice-writer + libreoffice-calc).
