+    This usually does not correspond to a "hard" page-break inserted by the document
+    author, rather just that Word ran out of room on one page and needed to start
+    another. The position of these can change depending on the printer and page-size, as
+    well as margins, etc. They also will change in response to edits, but not until Word
+    loads and saves the document.
+
+    Note these are never inserted by `python-docx` because it has no rendering function.
+    These are generally only useful for text-extraction of existing documents when
+    `python-docx` is being used solely as a document "reader".
+
+    NOTE: a rendered page-break can occur within a hyperlink; consider a multi-word
+    hyperlink like "excellent Wikipedia article on LLMs" that happens to fall close to
+    the end of the last line on a page such that the page breaks between "Wikipedia" and
+    "article". In such a "page-breaks-in-hyperlink" case, THESE METHODS WILL "MOVE" THE
+    PAGE-BREAK to occur after the hyperlink, such that the entire hyperlink appears in
+    the paragraph returned by `.preceding_paragraph_fragment`. While this places the
+    "tail" text of the hyperlink on the "wrong" page, it avoids having two hyperlinks
+    each with a fragment of the actual text and pointing to the same address.
