 * Inline preview for office documents (DOC / DOCX / XLS / XLSX / PPT /

 * Google's free gview rendering service.

 *
 * Limitations (documented for the integrator):
 *   - Requires public URL — won't work for auth-gated downloads.
 *   - First load can take 2-5s on slow networks.
 *   - Read-only — no editing, no print/share buttons.
