Word treats the end-of-cell mark as a paragraph in the default (Normal)
style, so a cell's last paragraph with contextual spacing in that style
(or in an undefined style, formatted as Normal) loses its space after, as
beside any same-style neighbour; one in another style keeps it.
`layout_box` kept the space after of every last cell paragraph except
automatic spacing, so the row grew by it and the text below the table sat
that much lower (docxide-pdf cell-end-text-context, cell-end-empty-context:
8 pt).
A middle or bottom cell of a row split across pages lines up with the
other cells' kept text, which `align_in_part` counted with its full space
after; it now stops at the cell's content end, so a dropped space after
(contextual or automatic) no longer pushes the aligned cell down.

* layout: line numbers take the "Line Number" style, not a fixed 10 pt grey
Line numbers were laid out in 10 pt grey in the default font, whatever
the document said. Word formats them with the "Line Number" character
style over the document's defaults: in a manuscript whose defaults are
Aptos 12 pt, Word's PDF shows them in Aptos 12 pt black (measured in
Word for Mac), WordCraft's in 10 pt grey.
Lay the number out with the document's "Line Number" style when it has
one, else its plain defaults, so size, font and colour follow the
document.
Test: line numbers take the document's default size and automatic
colour, and a "Line Number" style's size and colour when there is one.

Word for Mac sets raised and lowered text at 0.65 of the run's size
rounded to the half point (measured from digit advances in its PDF
export at base sizes 8 to 36 pt: 11 pt -> 7, 12 -> 8, 24 -> 15.5).
WordCraft used 0.65 exactly, so lines with superscripts were up to
0.5 pt wider and some broke a word early.

* #5843: resolve LibreOffice semicolon-separated font fallback lists to first installed family
* #5843: address review comments on font fallback list resolution
* #5843: verify fallback list text on cache hit and accept Times New Roman in tests
* #5843: bound the fallback lists read from a DOCX and reuse their classification
A document could name thousands of fallback families in `w:ascii`/`w:hAnsi`.
Nothing bounded that value, and the name-based rules (roman classification,
Thai family, named substitutes) then scanned every candidate for each shaped
piece, so opening the document took seconds.
`w:ascii` and `w:hAnsi` now keep the leading families within MAX_FONT_NAME
bytes, cut at a `;` so no name is split, as `w:cs`/`w:eastAsia` already bound
their names. The family a real list would pick is kept: a LibreOffice list
names a few families, well under the bound.
The Thai-family and named-substitute answers are worked out once per list and
kept in the fallback-list cache, keyed by the list text, so shaping no longer
rescans candidates for every piece. Resolution still reads every candidate.
A 500-paragraph document whose font names 20,000 candidates laid out in 10.8 s;
bounded on read it takes 17 ms.
Tests:
- a hostile fallback list keeps its leading families, cut on a `;`
- a real LibreOffice list is read whole
- a later Thai or named fallback still classifies, and lists are cached
Word drops the space before of an empty paragraph that follows a document's
leading floating table: its PDFs of docxide-pdf's leading-empty-before-float-0
and -12 put the text after the empty anchor (beside the table) at the same
place for 0 pt and 12 pt before.
Flow::gap_before (crates/layout/src/flow.rs) kept it: a floating table
takes no room in the flow and clears `pb.prev`, so the paragraph after it
was laid out like a document's first paragraph, with its full space before.
It now drops it for body block 1 when block 0 was placed floating on this
page (the page's float_tables), the page is fresh and the paragraph holds
nothing but markers (bookmarks, comment and permission ranges). It
doesn't check that the paragraph sits beside the table, so below a
full-width leading float an empty paragraph loses its space before too;
that case is untested. Later pages and columns, and paragraphs with text,
keep their space before.

A floating table with tblOverlap=never that is moved below another floating
table steps in to its distance from the text's left edge only in Word 2013
layout (compatibility mode 15). clear_of_float_tables read the mode from the
legacy shift, the first cell's left margin before mode 15, being zero, so a
mode 12 table whose first cell has no left margin was taken for Word 2013
layout and moved 9 pt right (docxide displaced-anchor-*-compat12-overlap0-*:
Word 72 pt, WordCraft 81 pt). Pass the mode itself.

UAX #14 allows a break between a full stop (IS) and an opening
parenthesis (OP), so `break_positions` (crates/layout/src/para/paragraph.rs)
let "29.05.2023г.(оформление ЗУ)" and "2023.(Example detail)" wrap after
the full stop. Word keeps such a token whole and wraps it at the space
before, as the docxide-pdf dot-open-token* Word references show. The
break between the two is now dropped (before the kinsoku pass, so
break-anywhere wrapping still applies).
Test: layout::tests::a_full_stop_before_a_parenthesis_is_no_break.

A row is split across pages from its flattened items, so a row of a nested
table marked w:cantSplit was cut between its lines like any other text in
the outer cell. Word leaves such a row whole: the outer row moves to the
next page whole when that row comes first in it (docxide-pdf
nested-first-row-prefix300/330-cant1), and otherwise splits above it
(inferred).
table_flow now moves the cut up to just below the top of the highest nested
Can't Split row it runs through (nested_keep_cut): the outer row's bottom
band below that top, so the text and nested rows ending there stay on the
page. A row runs through the cut when it ends below the room left for text,
as in the split itself; one walk over the rows from the lowest top up moves
the cut until none does. A vertically merged cell doesn't stretch its row's
band, and a cell aligned to the middle or bottom is measured from its top, as
the split runs it. This applies to the first part of a row and to the kept-chain and
header-row checks. On a fresh page, where moving on gains nothing, a nested
row taller than the room still splits at the room rather than running into
the bottom margin.

* Layout: a picture in a paragraph whose hidden mark closes a section keeps its room (#5288)
A paragraph with a hidden mark and no plain text was a quiet mark: laid out
with no room, its drawing kept. An in-line picture adds no plain text, so a
hidden-mark paragraph holding only a picture qualified, and the text after it
(the next continuous section in the report) was drawn over the picture. Such
a paragraph, or one holding a note reference mark, now keeps its line; one
with only floating objects stays quiet.

* Layout: a legacy check box in a hidden closing mark keeps its room too (#5288)
A FORMCHECKBOX field has an empty result, so a hidden-mark paragraph holding
only a check box still counted as quiet and the next continuous section was
drawn over the box. Fields now count as visible content when the paragraph
layout shows them as something other than their result: their code, a legacy
check box, or a drop-down's entry (the same test as the layout's `field`).

Word wraps "Dataprotection-/Secrecyviolation" as "Dataprotection-" /
"/Secrecyviolation". UAX #14 (LB13) forbids a break before the slash, so
the compound had no break opportunity: lines moved it whole and auto-fit
table columns widened to fit it, taking width from their neighbours.
Add the break after U+002D when a slash and a letter follow, next to the
existing break before a digit (#2712); Word keeps "fitness-/1589" whole,
so a slash before a digit gains no break. Always sort the added breaks.

A file that turns an inline picture but writes no wp:effectExtent (or a zero
one), as other tools do, makes Word keep the picture's line to its frame and
let the turn overhang it, cut at the line's top and bottom: the frame as it
is in Word 2007 layout (compatibilityMode < 15), with width and height
exchanged from 45 to 135 and 225 to 315 degrees in Word 2013+ layout.
WordCraft always reserved the exact rotated bounds (Float::spin_pad), which
is what Word's own files encode through their effect extents, so the text
after such a picture sat up to 34 pt too low (docxide-pdf
standalone-picture-compat12-* / compat15-angle45/135).
The docx reader now marks such objects (Float::bare_turn, cleared when the
object is turned again); the inline room comes from Float::line_pad, which
display uses too to place the frame in it, and the line clips the picture's
overhang. The writer keeps writing no turn overhang for them, so a save
round-trips. Word-saved pictures are unchanged.

* Layout: look at the text after a decimal tab once, not once per cluster
Text after a decimal tab is shifted after each of its clusters, and each
shift walked the text again from the tab to find its first '.'. A long run
without a '.' (soft hyphens take no room, so it stays on one line) made a
single paragraph's line breaking quadratic. The scan now carries on from the
cluster it reached.

* Arabic letters join across a change of formatting (#4093)
Each run of a paragraph was shaped on its own, so a letter at a run's edge
took the form of a word's start or end. A coloured letter stood apart from
its word, and a word edited with Track Changes on read with a space in it
(ال ذكاء).
Runs are now shaped with the text shown on either side of them, through the
shaper's pre- and post-context (fonts::ShapeContext). Runs left out of the
layout (hidden text, deletions in a final view) are skipped, so letters join
what is on the page. Only paragraphs with a joining script do the work.

* #4093 review: no letter joins a drop cap formatted on its own
A drop cap letter in a run of its own (coloured, say) was still passed to
the next run as the text before it, so that run's first letter joined the
drop cap, which is drawn apart from the word. The shown text now has a floor
past the drop cap, and no run takes context from before it. The drop cap
test also covers the letter in a run of its own.

Taken from MeHail-02's numbering-literal-none branch (46405e66), checked in Word
for Windows: a none level is an ordinary level whose own number reads as
nothing. It counts and restarts the levels below it, stays empty in legal
numbering, and an empty label still tabs the text to the indent unless it
already ends there (the Chapter 1 list's Heading 2 stays at the margin).

* #4985: STYLEREF in full context keeps a none-level heading's parent
Review: a none level now has a label, so its headings reach the style index,
which leaves the none level out of the levels it keeps; \w and \r took the last
kept level for the heading's own and dropped the parent. Levels now carry their

number is suppressed to nothing.

count now.

spans of the values its template shows, with their delimiters (a letter number
only standing apart from other letters); \s takes the last of them.

A picture lowered further than its own height had its lowering cut at that
height. Word keeps its top on the baseline but lowers the line as far as the
position says: a 6 pt picture lowered 30 pt makes a 30 pt line. Exact spacing
keeps the line's baseline. Closes the gap noted with #3984: all 156 measured
lines now match Word.

An exact-spacing line keeps its baseline when a picture is lowered past its
