* Layout: a picture lowered past its height lowers its line as far, as in Word
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.
* Lowered pictures: an exact-spacing test; gaps and progress log
An exact-spacing line keeps its baseline when a picture is lowered past its
height (the test fails without the cap). Gap 4 and the progress log note the
change.

* fix(fields): quoted-argument backslash escapes and body PAGE in a cardinal-text section
A backslash inside a quoted field argument makes the next character literal, so TITLE "x \* Upper" shows x * Upper as Word does. A body PAGE field now uses the section's page number format (cardinal text shows words), as headers and footers already did.

anchors_walk_dense_unrelated_markers_in_linear_work compared CPU times of
a few microseconds, so cache and timer noise could push the ratio past its
24x limit on a linear walk (43.52x in a CI run).
wordcraft-doc now counts, in tests only, the characters its paragraph
object lookups walk (objects_before, object_offsets and
objects_with_offsets), through a work::count helper behind the existing
test-support feature. The test asserts that 8x the markers take at most
12x the steps, as the layout linear-time tests do: the walk takes 2001 ->
16001 steps (8.0x), and the object_offsets + object_at walk it replaced
takes 2003001 -> 128024001 (63.9x).
- update_generated keeps what precedes a wrapped list's field (r4468529243)
- from_doc keeps objects in hidden text when hidden text is written (r4469018820)
- clipped cell lines in a turned frame are drawn once, clipped, turned (r4469018900)
- kept::while_writing works out reply map and page fingerprint once per export (r4468529227)
- odt_charts fixture declares its namespaces (r4468529259)
- guard test for character styles based on a missing parent (r4469018843, not a bug)
- odf.preset: word (Microsoft Word style, default) or libreoffice; wordcraft still read as word
- Options, CLI (WORDCRAFT_ODF), docs and ROADMAP follow the two styles
- CodeRabbit: kept groups and story fingerprints follow fill_objects; padding serde default;
list field depth; literal doubled quote; ASK/SET results not exported; dc:date offsets;
first_pages order; unique picture names; finite raise clamp; PDF rotated-text guard;
.ott in the password message; flat element bounded by depth; cell tile fallback;
ROADMAP and docs reconciled
- Remove clean-room wording from the ODT tests
* Gap 4: flag document fonts that aren't installed
The font box (ribbon, mini toolbar, both Font dialog boxes) shows a
warning mark when the current font isn't installed; its hover note
names the font drawn instead. The status bar says "N fonts not
installed" and lists each with the faces drawn instead, plus Add Font….
Agents get `font.missing` and `format.state.fontShownAs`.
Layout records, where it picks a face per text segment, the fonts the
shown text asks for that aren't installed and the faces drawn instead
(ParaLayout::substituted, DocLayout::substituted_fonts), so hidden
text, unused styles and orphaned stories never count; list labels,
field results and East Asian and complex-script text do, and so does a
missing roman font drawn in Cambria. Metric-compatible substitutes and
symbol fonts drawn as Unicode aren't flagged. Bounded for hostile
files: 64 pairs a paragraph, 1024 a document, names kept to 256
characters, 20 rows in the popup.
Ported from alehel/wordcraft#1 onto current main; English strings only
(translations belong in storytold/craft-i18n).

* Gap 4: missing-font review fixes
- Judge a padded font name by the face layout drew for it, and skip blank names.
- Name the face CJK text is drawn in for a missing East Asian font, not Cambria.
- Keep the missing-fonts list per window, so several windows don't rebuild it every frame.
- Expose the font box's warning to screen readers as its description.
- Count missing fonts with craft-i18n plurals (`i18n::tn`).
- One table of metric twins (`fonts::word::METRIC_TWINS`): a missing font is drawn in an
installed twin first, and the warning reads the same table.
- Find the status-bar item by part of its label in the click test.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Gap 4: warn for a font picked at the caret; drop fonts of hidden list items
- At a collapsed caret the font box warns for a missing font typing will use, also at the end
of text in another font (it waited for the first letter).
- A list item that shows nothing (#3982) reports no missing font: its number was shaped, and
its font recorded, before layout dropped it.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Gap 4: say where Add Font… is, and that it needs the font file
The font box's note said "Add Font… installs it": Add Font… opens a file picker at the end of
the list, so it only helps with a font file at hand.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Gap 4: docs say the popup lists 20, and when the font box warns ahead
CodeRabbit review: the status-bar popup lists the first 20 missing fonts, then a count; the font
box also warns at a collapsed caret for a font no shown text uses yet; `fontShownAs` is the
font's substitute, fallback faces aside.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Gap 4: the Font dialog warns for a missing font over a selection
CodeRabbit review: the dialog's boxes show the fonts OK applies, which no shown text may use
yet (an Asian text font over Latin text, a font typed into the dialog), so they name the
substitute whatever is selected. The ribbon's box over a selection still reads the list.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Gap 4: the Asian font box names the face CJK text gets
CodeRabbit review: the status bar's list is by font name, so for a font Latin text also uses
it named the Latin text's substitute. The Asian text box now always looks up the face layout
draws Chinese, Japanese and Korean text in.

Conflicts kept both sides. Where the two branches met:
- Para.mark: both added it. It stays CharProps (ODT needs it); HTML's
`<p> </p>` converts its Fmt, and to_doc reads it in one place.
- Arrowheads: the PR's line ends (top left to bottom right) with main's
arrowhead styles.
- inline_rect: the PR's depth below the baseline with main's rule room.
- Spacing and Cell literals take main's new fields.
- The zip entry guard (#3660) also covers the encrypted ODT paths, which
parsed a package before it; regression test in tests_more/encryption.rs.
- chunks_exact to as_chunks in odt/frames.rs and odt/path.rs (clippy).

* #3867: review — header repeats, picture outlines and linked-box widths bounded the same way every layout
- Header repeats: a Clip (floating Drawing Canvas) counts its members, depth-bounded, so a 1000-member canvas no longer counts as one item (CodeRabbit thread 4373103686); the budget is per layout (Ctx), not per table.
- Tight-wrap outlines: each cache entry stores its picture's pixel cost; a cached hit is charged to the layout's decode budget like a decode, so cold and warm layouts (and the CLI) wrap alike.
- Linked boxes: widths are budgeted by laid-out work (MAX_FLOW_WORK), not 16 widths, so ordinary stories keep exact widths for every box.
- header_rows.contains -> index compare; layout-parity doc revision.

* #3867: review — a picture that fails to decode still costs its pixels when cached; header repeats restored on retry
- contour: Alphas records the pixels each picture charged (costs map), also when the body then fails to decode, so the cache entry's cost is right and warm layouts charge it like cold ones.
- Snap saves and restores ctx.header_repeats so balance_pass retries don't keep their charge.
- Tests: truncated large PNG cold vs warm; canvas header row end to end through place_table; linked-chain bound <= 8; vertical box's layout differs from every other box's.

paragraph_issues dropped issues touching a run left unchecked by testing
every run of the paragraph against every issue. A paragraph can have many
runs and many issues within the proofing size limit, so the filter was
quadratic in the paragraph's size. The unchecked ranges are now merged and
sorted once, each issue is looked up by binary search, and paragraphs
without unchecked runs skip the filter.
Widow and orphan control a file doesn't state is open in the standard
(it refers to XSL, whose initial value is 2); LibreOffice reads it as
off. It is now a profile case (widowControl), and WordCraft writes it on
its default style either way.
LibreOffice measures tab stops from the paragraph's indent when its
TabsRelativeToIndent setting is on (its default), default stops too
(measured). WordCraft's layout now counts default stops from the indent
for such documents, and writes them back measuring from the indent
instead of from the margin, which moved LibreOffice's default stops.

* #5290: Page Up/Down move by a page in Outline, Draft and Web Layout
These views lay the document out as one long page, so caret.pageUp/pageDown looked for a previous or next page, found none and left the caret where it was. Move by the text area height of the caret's section instead, the same distance Print Layout moves.
* #5290: Page Up/Down pick the line past the caret, and page from a hidden outline selection end
Choose the destination among the lines past the caret by height first (DocLayout::line_toward), so narrow right-indented paragraphs can't keep the caret on its own line when the step is short. The above/below test is shared with vertical().
In Outline view, a selection that ends in text a collapsed heading hides pages from where the outline shows it (outline::shown_pos, pulled out of after_command), keeping the anchor. Avoid f32::clamp, which panics on a NaN page height.
LibreOffice's elegant agenda puts a small gradient picture behind cells
(§17.3 style:background-image in a table-cell style). Cells can now
carry a background picture (CellProps::picture: media, own size,
repeat none/tile/stretch, alignment), which layout draws over the
cell's shading and under its text, clipped to the cell (Placed::Clip of
Placed::Image; tagged as an artifact in PDF). The ODT reader reads it
(style:repeat, style:position, the picture from the package) and the
writer writes it back with the picture in the package (once per
picture).

Found by saving WordCraft's own documents as ODT and opening them in
LibreOffice (42 documents: templates, themes, one per feature).
- Table styles: ODF has no table styles of Word's kind, so each cell now
states what the style gives it (fills, its borders, bold header text,
its paragraph spacing), under the paragraph's own styles as layout
applies them (ECMA-376 §17.7.2; StyleSheet::table_para_patch and
table_char_patch). The style's border mapping moved to
styles::part_borders, shared with layout.
- Tables read from ODT no longer get Word's Table Grid style, whose
single spacing changed their text.
- Columned sections say whether their columns end balanced
(text:dont-balance-text-columns, §20.428, read as its name says; its
value descriptions contradict it). Unstated, the ODF profile decides
(balanceSectionColumns: LibreOffice balances, WordCraft as Word).
SectionProps::balance_columns carries it to layout.
- SmartArt diagrams are saved as a draw:g of their shapes and text (with
an invisible frame keeping the graphic's box), which LibreOffice draws
as WordCraft does.
LibreOffice round-trip corpus: 40k differing pixels over 125 documents

What ODF 1.3 defines, including XSL's initial values for fo: properties,
is followed whatever the settings: unstated page margins are now 0, and
padding without a border takes room in every ODT document. What the
standard leaves to the application (Part 3 §16.2) is an OdfProfile:
WordCraft's own choices by default, LibreOffice's, or custom values.
The profile fills in only what a file leaves unsaid; stated values win
under every preset (tests_more/profile.rs).
Cases: header height, how its height and spacing combine, dynamic
spacing, tabs from the indent, column gap, shape fill, line and
hairline, page frames against a paragraph, in-line frames against a
paragraph or page, and lines of only pictures.

* DOCX: VML horizontal rules take their line
A web page's <hr> pasted into Word is a VML rule: `v:rect` with
`o:hr="t"`, often `width:0`. WordCraft took the width as written and
drew a 1 pt dot where Word draws a line across the page.
Measured on Word with a synthetic document: a rule with no width and
no `o:hrpct` spans the line inside the paragraph's indents; `o:hrpct`
is a share of it in tenths of a percent (500 = half); `o:hrpct="0"`
keeps the shape's own width; `o:hralign` places a shorter one (left,
centre, right); `fillcolor` and `stroked` apply as to any VML shape.
WordCraft now matches each case within 0.1 pt.
- wordcraft-doc: ShapeExtra::hr (HorizontalRule: share, alignment,
Word's standard look).
- wordcraft-docx: `o:hr`, `o:hrpct`, `o:hralign`, `o:hrstd` read; a rule
is written back as the same VML rule (DrawingML has none), and Word
opens the re-saved file with the same lines.
- wordcraft-layout: a rule takes its whole line and is drawn at its
share; measured for a table column it asks for no width, so it
follows its column. (Word draws a rule in a cell at the page's text
width, centred on the cell and past its edges; it stays in the cell
here.)
docs/file-format-parity.md is updated.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Horizontal rules: only an inline, shown rule is one
Review: the rule arm of the writer ignored the shape's placement, so a
rule imported with position:absolute or visibility:hidden came back
inline and visible. Only a rule in the text and shown is read as a rule
now (a pasted <hr> is one); a positioned or hidden one stays a plain
shape, which keeps both when saved. The writer checks the same.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Horizontal rules: a see-through fill is kept; column measuring asks for the right width
Review: `write_hr` wrote only the fill's colour, so a rule with `v:fill
opacity` came back opaque after a save; the opacity now goes back as `v:fill`.
Review: measured for a table column, every rule asked for no width, so one of
its own width (`o:hrpct="0"`) could end up clipped by a narrow column; it now
asks for its width. AutoFit to contents measures on a line of its own width
that the rule took for a real line, so a rule sharing its line made the
column as wide as it could go; any measuring width now counts.
`Placed::Shape` boxes its extras: with the rule, `Placed` went past clippy's
large_enum_variant limit.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Horizontal rules: placed in what the line has left; rotation and flips kept on save
Review: a whole-line rule ignores a first-line indent or a line narrowed by a
float. Measured in Word, it does too: the width stays the share of the
paragraph's width and the rule runs past the margin, or under a float on its
right. What did differ was the placement: Word centres and right-aligns a rule
in what the line has left, with a first-line indent moving the end of that room
along, and a right-aligned rule beside a float was drawn off the page here. The
display now places it that way (`ParaLayout::rule_room`).
Review: a save dropped a rule's rotation and flips; they now go back in its
style, as Word writes them.

A shape's fill colour can carry a:alpha, its opacity. WordCraft dropped

Found with LibreOffice's report templates and one-page résumé.
Padding without a border:
- LibreOffice gives a paragraph's padding room on every side, with or
without a border; measured, 0.5 in of padding and no border moves the
text 0.5 in in and down. WordCraft dropped it.
- The reader now keeps it (an invisible border holding the space; a new
`Borders::takes_room()`), and the writer writes it back.
- The layout adds it to the spacing or indent under the document
setting, now renamed `Settings::odf_layout` to cover all of
LibreOffice's layout rules. `ResolvedPara::padding` carries it, so
Word documents are unchanged.
Columns:
- Unequal columns (`style:column` relative widths and indents, on pages
and sections) were made equal. They now keep their widths and are
written back as shares. The writer leaves out `fo:column-gap` beside
them, because LibreOffice ignores a page's column widths when a gap is
stated (checked).
- Columns with no stated gap have none, where they had Word's 0.5 in.
- A paragraph starting a column (`fo:break-before="column"`) now starts
with Word's column break, written back on the paragraph.
The report templates round-trip to 0-11 differing pixels (from up to
9,600), and the résumé to 24 (from 6,286) with its text the same.
Across the corpus the round-trip difference falls from 155k to 82k
pixels. WordCraft's own rendering difference falls from 469k to 428k,
and no document gets worse.

LibreOffice sizes a line holding only in-line pictures by the pictures
alone. Its font's ascent and descent don't count: measured in
LibreOffice, a 3.6 pt rule's line is 3.6 pt, where WordCraft (following
Word) made it 15.5 pt.
- A new document setting, `Settings::object_lines_fit_objects`, makes
the layout size such lines by the pictures alone. The ODT reader turns
it on, so other documents keep Word's layout. An equation or any text
on the line keeps the font's height.
- A document with no page layout at all (no styles.xml) opened on Word's
Letter page with 1 inch margins. It now uses the region's paper with
LibreOffice's 2 cm margins.
WordCraft's own rendering of LibreOffice's elegant agenda comes close to
LibreOffice's: its pixel difference halves, from 17,428 to about 8,950.
Across the corpus WordCraft's rendering difference falls from 487k to
469k. No document gets worse, and round trips are unchanged.

Found with LibreOffice's report templates.
Tables:
- A table filling the margins (`table:align="margins"`) but wider than
them ran off the page. It is now fitted to the text width, its columns
in proportion. Checked in LibreOffice, which fits such a table with or
without relative column widths; the old test's claim otherwise is
corrected.
- A table's own space above and below (`fo:margin-top` and
`fo:margin-bottom` on the table) was dropped. It is now read into new
`TableProps::space_before`/`space_after`, laid out (added to the
spacing of the paragraphs around it, as LibreOffice does) and written
back.
Headers and footers:
- A header taller than its band lost its spacing from the body, moving
the text up. LibreOffice keeps the spacing below the content unless it
is dynamic (`style:dynamic-spacing`, which behaves as Word does). New
`SectionProps::header_gap`/`footer_gap` hold it. The layout keeps it
past a tall header or footer, and the writer writes it back. Word keeps
no gap, so DOCX documents are unchanged.
Across the 125-document corpus, the round-trip pixel difference falls
from 241k to 185k, and WordCraft's own rendering's difference from
LibreOffice's falls from 562k to 484k. No document changes page count or
gets worse; one report template falls from 7,646 to 602 pixels.

- A table starting a page (`fo:break-before="page"` on the table,
LibreOffice's agenda minutes) didn't. Its first paragraph now has a
page break before it, and it is written back on the table.
- Layout: a page break before the paragraph in a table's first row
now moves the whole table to the next page, as Word does. It was
ignored; this matters for Word documents too.
- ODT tables are now fixed layout (Word's `w:tblLayout`).
LibreOffice's columns never fit their content.
LibreOffice's 6orange agenda now round-trips with the same text.

* Count the runs proofing text walks, instead of timing it (#5185)
`proof_text_walks_the_runs_once` was the one linear-time test here that timed
its walk, and the ratio crept over its 24x limit when the crate's tests ran in
parallel -- 28.2, 26.4, 25.6 -- from cache and memory contention rather than
from any regression.
The file's own module doc says why the others don't have this problem: "The
cost is the steps the lookups' walks count (crate::work), not a timing, so a
busy machine can't make a linear lookup look quadratic or the other way round."
It then says this one is timed because "proofing text, whose walk is the
document model's" counts no steps -- but `proof_text` does the walk itself,
advancing a runs iterator alongside the text, so it can count the runs it looks
at like every other walk here. Nothing in `wordcraft-doc` had to change.
before 8x the runs took 28.2x the time (limit 24), under load
after 50000 steps for n, 400000 for 8n, ratio 8.0 (limit 12)
The count is the same on any machine under any load, so the flakiness is gone
rather than made less likely: raising the limit to 32x would have left the same
failure available on a busier machine. It is also about 100x faster -- 0.03 s
against three rounds of eight repetitions -- and `work::steps` is `#[cfg(test)]`
inside, so release builds are untouched.
The test still catches what it was written for. Putting the quadratic walk back
(the run for each character found from the first run, every time) gives:
proof_text: 1250025001 steps for n, 80000200001 for 8n, ratio 64.0
panicked: 8x the input took 64.0x the steps: not linear
Verified under the reported condition: three runs of the whole crate suite in
parallel, 559 tests, all green.

Word's Font › Emphasis mark (a mark over or under each character, used
to stress East Asian text) wasn't modelled. DOCX `w:em` and ODT
`style:text-emphasize` were dropped.
- Model: `CharProps::emphasis` (dot, comma, circle, dot below, or none
to turn off a style's).
- Layout: a mark is drawn over (or under) each character, and the line
is made taller to fit it.
- `format.emphasisMark {"mark": …}` sets it, and Format state reports
it. The catalog lists it under Home › Font.
- DOCX: `w:em` is read, and written in its place in `w:rPr` (after
`w:cs`, before `w:lang`).
- ODT: `style:text-emphasize` maps to it: an accent is the comma, a
disc the dot, a dot below the under-dot.
Also fixes two problems from the previous commit (ODT variables):
- Field updates blanked a SET field's stored result. The layout
already draws nothing for SET, so its result stays as it was, as
`ask_and_set_fields_draw_nothing` pins.
- A clippy lint (manual char comparison) failed.
