Read a paginated batch of content blocks (paragraphs and tables) from a .docx file. Returns items, total, offset, limit, and has_more — loop with increasing offset until has_more is false. Blocks carry style name references only; use get_styles_from_docx for full style definitions.

Write content blocks to a .docx file. Creates a new file if the path does not exist; replaces the document body if it already exists. Pass blocks collected from get_contents_from_docx. Call before write_styles_to_docx when reformatting.

Read a paginated batch of paragraph style definitions from a .docx file. Returns paragraph_styles, total, offset, limit, and has_more. The section field (page size and margins) is included only in the first batch (offset=0). Merge all batches client-side before calling write_styles_to_docx.

Union paragraph style definitions onto an existing .docx file. The target file must already exist — call write_contents_to_docx first. Incoming styles win on name conflict. Pass a StyleProfile dict with paragraph_styles and optional section from get_styles_from_docx batches.
