Document Formatting Showcase — generates document-formatting.docx exercising the
docx `document` property surface (schemas/help/docx/document.json): the
document-level settings that have no per-paragraph equivalent.

`document` is a read-only container addressed at path "/"; you never add or
remove it, only `set`/`get` its properties. They fall into seven groups:

  Metadata     — author/title/subject/keywords/description + extended.company/...
  Page setup   — pageWidth/Height, orientation, margins (mirror/gutter/book-fold)
  docDefaults  — the document-wide run/paragraph defaults unstyled text inherits
  Theme        — theme.color.accentN / dk/lt / hlink and theme.font.major/minor
  CJK grid     — docGrid.*, autoSpaceDE/DN, kinsoku, overflowPunct
  Fonts        — embedFonts / embedSystemFonts / saveSubsetFonts
  Display      — evenAndOddHeaders, autoHyphenation, defaultTabStop, privacy flags

Like examples/excel/conditional-formatting.py, this drives the officecli Python
SDK (`pip install officecli-sdk`): one resident, writes shipped over the pipe.

Usage:
  python3 document-formatting.py
