Browser-native file preview, CAD viewing, document rendering, and developer tooling.

- Browser first: prefer static deployment, local parsing, and private-file friendly workflows.
- Production oriented: focus on real business files, large documents, workers, WASM, lazy loading, and predictable integration APIs.
- Framework friendly: keep core capabilities framework-neutral, then provide native packages for mainstream ecosystems.
- Clear ownership: each repository documents its package name, build output, license, and integration path.
