Silurus/ooxml: Pixel-faithful Office documents, rendered in the browser

Silurus/ooxml is a browser-based viewer for Office Open XML documents that renders to an HTML Canvas element. The parsers are written in Rust and compiled to WebAssembly, while the renderers use the Canvas 2D API. The entire codebase was implemented by Claude through iterative prompting with no human-written application code. Each format exposes a headless engine for custom UI composition.
