+  drawing in a table cell went into that cell only when the cell held it across, and a dot
+  set in a column of its own beside its entry's text — `CharcoalGold`'s timeline, a row of
+  date, gap, dot, gap and text — had no paragraph to go to, so it stayed on the page. It now goes
+  into the first paragraph of the cell of the same row that holds it, placed from the row's top:
+  measured in Word 16.0.20430 and LibreOffice, both start each cell's first paragraph there
+  where the cells set their content from the top, every cell of a row taking the row's largest
+  top margin. A drawing in the body may now also rise above its paragraph's top by its own height,
+  24pt at most, as a dot centred on the paragraph's first line does; both editors place it
+  there and draw it whole. In a table cell it still rises by a stroke's width at most: a rule

 - **A DOCX's drawings move with the text they stand beside.** Most shapes the page paints — a
   timeline's dot, an icon by a heading, a skill's bar, a badge — were placed from the page's
   edges, so when a reader edited the text above one, the text moved and the shape stayed. A shape
   standing beside a paragraph's text is now anchored in that paragraph and placed down from its
