DOCX Engine
Word documents that hold up after handoff.

Tables
Striped, bordered, modern styles with column spans and widths
Lists
Bullet, numbered, lettered, roman — with arbitrary nesting
Structured layout
Deterministic columns, stacks, and grids for reliable Word output
Images

Pagination
Page breaks, headers, footers, page numbers
