+- **A DOCX export stands a table's text cells on the page's baselines, and what follows a
+  paragraph or a ruled table where the page sets it.**
+  - **A row of text cells is moved by its margins.** The page sets a cell's line its face's ascent
+    below the line's top; Word stands an exact line's baseline four fifths of the way down it,
+    whatever the face. A cell's text stood as far off as the two are apart, at the top, the middle
+    or the bottom of the cell: a line of 8pt Poppins 0.58pt low in Word and 0.55pt in LibreOffice,
+    of Helvetica 0.24 and 0.16pt, of Lato 0.24 and 0.25pt high (measured). Both editors give every
+    cell of a row its largest top and bottom margins, so the row's top margin is made smaller and
+    its bottom one as much larger — or the other way — by the least any of its cells calls for, no
+    further than the margin holds: every cell's text moves with its room, and the row keeps its
+    height. Measured, the lines then stood within 0.04pt of the page's in Word and 0.09pt in
+    LibreOffice. A row is not moved where its cells call for opposite ways or its least call is
+    under a tenth of a point. Not a row holding a composed cell, whose paragraphs their own writers
+    seat where they can, nor a row the layout did not measure, nor one in a vertical merge. What the
+    margins leave of a cell's call, half a point and more, is moved by its text's position, as a
+    paragraph's is: a cell of 8pt Poppins beside one of Lato, the two called opposite ways, stood
+    0.58pt low.
+  - **A paragraph written at its tallest line owes what its rounding takes.** Its lines are
+    written to the twip, and what that took from the page's height over several lines stood what
+    follows higher: `ModernInvoice`'s address blocks, six lines of 11.475pt written at 11.45,
+    stood the table under them 0.15pt high in both editors. It is owed below the paragraph, as a
+    paragraph written at another height owes what it falls short.
+  - **A table's rules come off its padding as wide as Word draws them**, in eighths of a point: a
+    0.7pt hairline is drawn 0.75pt wide, and taken off at 0.7 it stood `EditorialProposal`'s tables
+    and all under them a step of Word's grid lower. A cell's rule is written from two to
+    ninety-six eighths, the range of a line border's width, as a paragraph's rule is.
+
+  In the DOCX fidelity corpus 12 documents stand nearer the page in Word, the sum of the medians
+  1.45pt nearer — `invoice-consulting_long`'s median line from 0.74pt to 0.35pt,
+  `invoice-classic_long`'s from 0.26pt to 0.06pt, `invoice-subscription`'s from 0.56pt to 0.43pt —
+  and 12 in LibreOffice on Windows, 1.38pt, `invoice-consulting_long`'s from 0.69pt to 0.22pt.
+  `invoice-modern`'s moves from 0.08pt to 0.12pt in Word and from 0.07pt to 0.13pt in LibreOffice:
+  its table's text, set low in its cells, had stood where the page sets it only because its rows
+  stood as much high, and the notes under the table stand 0.1pt lower, where Word leaves more space
+  after a table than the page does. `cv-editorial_blue`'s skills table now stands with the column
+  round it, which LibreOffice sets 0.1 to 0.3pt high: its median there from 0.09pt to 0.14pt. The
+  report names nothing more.
