inspect_pptx_text.py
  Lists every place a .pptx stores text: slide paragraphs, speaker notes,
  slide masters and layouts, charts, SmartArt, comments, and picture alt
  text. Flags paragraphs whose formatting or links are split across runs,
  and paragraphs that contain a manual line break or a field.
  Needs Python 3 only. Reads the file; never writes to it.
    python3 inspect_pptx_text.py deck.pptx
    python3 inspect_pptx_text.py deck.pptx --all   (also show layout prompts)

sample-deck.pptx
  A 3-slide test deck with text on slides, in a table, in speaker notes, in
  a chart, in picture alt text, and in a text box on the slide master.
  Slide 2's first bullet has a bold phrase and a link on its last words;
  its second bullet has a Shift+Enter line break. It contains no SmartArt
  and no comments.

build_fixture.py
  Rebuilds sample-deck.pptx with python-pptx 1.0.2:
    pip install python-pptx==1.0.2
    python3 build_fixture.py sample-deck.pptx
  ZIP timestamps differ between builds, so a rebuilt file will not match the
  hash below byte for byte; its XML content will.

How the article's results were produced
  We ran sample-deck.pptx through the paragraph rewrite used by
  BookTranslator's PPTX handler as of 2026-10-31, reproduced locally. The
  "translation" was a placeholder that adds "[DE] " in front of each
  paragraph, so no language model was involved and the results show only
  what the file handling keeps, moves, or drops. One result: the title
  "R&D team" is stored as R&D, reached the placeholder in that escaped
  form, and came back displayed as "R&D". Real translations will also
  change text length.
