LibreOffice as JavaScript idiomatic WebWidget + Library
summary
Runs a full LibreOffice build inside the browser via WebAssembly and a zjs wrapper that exposes the UNO API to normal JavaScript; the office process lives in a web worker, writes files to a virtual FS (emscripten-like) and produces downloadable PDFs. The static payload is about 32 MB and serves from a tiny static server (Raspberry Pi is sufficient). Demonstrates automating document edits, spreadsheets with live charts, event hooks, and the real issues: multi-threading via web workers and Spectre/Meltdown-driven memory isolation caveats.
