Office conversion
Office to PDF, locally
First implementation: extract OOXML text from DOCX/PPTX/XLSX and print it into a clean PDF.
This is not pixel-perfect Office rendering. True lossless Office-to-PDF requires a full layout engine, font metrics, pagination and chart renderer, usually delivered as a large WASM core.
