# DOCX PDF runtime assets

- OOXML renderer: `@silurus/ooxml@0.86.1`, https://github.com/yukiyokotani/office-open-xml-viewer, MIT. Unmodified reachable DOCX files are in `../../ooxml/0.86.1`; its LICENSE and THIRD_PARTY_NOTICES.md apply. `ooxml-assets.json` lists source hashes; shared PPTX files were checked byte-for-byte before reuse.
- PDF writer: `pdf-lib@1.17.1`, https://github.com/Hopding/pdf-lib, MIT. Unmodified browser ESM bundle; see PDF-LIB-LICENSE.md.
- Font parser/subsetter: `@pdf-lib/fontkit@1.1.1`, https://github.com/Hopding/fontkit, MIT as declared in its included FONTKIT-README.md and package metadata. Its published ESM build was bundled with esbuild (browser, ESM, ES2020, minify, legalComments:inline) to include its pako dependency; existing inline notices are retained. The package README is included unmodified.
- pako: included by the fontkit bundle; see PAKO-LICENSE.
