* Fix#1974: the caret and clicks land between the letters of a ligature
The glyph's advance is shared evenly among its letters (mirrored in
right-to-left text); ligature letters keep their character spacing.

* #1974: ligature tests use a bundled font that draws fi and ffi as ligatures
They assumed the installed default-font stand-in draws ligatures; Liberation Sans (Linux) draws
none, so they failed there.

* Layout: a word after a slash wraps whole, like Word (#2963)
UAX #14 (LB13) forbids a break between a space and a slash, and the break
after a slash is dropped on purpose (Word keeps "and/or" whole). Together
"caption /word" had no break opportunity at all, so a line too short for
both filled letter by letter and split the word. Add the break before a
slash that follows whitespace and starts a word.

* Layout: no break before a slash after a no-break space (#2963)
The break before a slash word took any whitespace, U+00A0, U+2007 and
U+202F included, so "Nr. /12" could wrap after the no-break space.
Only a breakable space counts now. The parity checklist lists the rule
on its own row as untested against Word.

- Math straight in the body or a cell (m:oMathPara/m:oMath without w:p,
allowed by EG_BlockLevelElts) gets its own paragraph instead of vanishing.
- mc:AlternateContent Requires="m" picks the equation, not its fallback.
- Inside an equation, runs in w:hyperlink, w:fldSimple, w:dir, w:bdo and
mc:AlternateContent are kept (EG_PContentMath); depth stays bounded.
- w:sym, w:noBreakHyphen and Symbol-font text in math runs become Unicode.
- Layout: n-ary operators, delimiters, accents and group characters the math
font lacks use a fallback font instead of a missing-glyph box.
- Coverage test reads every ECMA-376 §22.1 element and checks no argument's
text is dropped; tests for body-level math, Requires="m", symbols, hostile
nesting and the font fallback. Parity docs and progress log updated.

A bullet stored as a private-use code (U+F0xx) in a font that isn't
installed, and that isn't a mapped Symbol/Wingdings code, fell back to
any installed face with a glyph at that code - an icon font such as
Font Awesome / Nerd Fonts, where U+F081 is the Twitter logo. Such a
bullet now shows the level's default bullet (• ○ ▪), so level 2 is a
hollow circle.

A paragraph in a Thai font that isn't installed (TH Sarabun New, Angsana
New, Cordia New, the UPC families…) drew its Thai letters in one fallback
face and the Latin letters, digits and baht sign in a Latin substitute at
a visibly different size. Word substitutes one font (Cordia New) for the
whole run.
Thai families now have their own substitute lists (Cordia New and
Leelawadee UI on Windows, Thonburi on macOS, Noto Sans Thai and the TLWG
fonts on Linux; serif families prefer Angsana New, Sathu or Noto Serif
Thai), and the first listed face with Latin letters and digits as well
as Thai wins. When the substitute still lacks some of the run's Thai or
Latin text, the run moves to one face covering it through
FontDb::fallback_for_run, the generalised East Asian run fallback. Only
Thai fonts get this: a missing Latin font keeps Latin text in its own
substitute, a run with its own complex-script font keeps it for the Thai
letters, and a missing roman-classed Thai font is no longer drawn in
Cambria.

While landing community PRs, a few rows in gaps.md, layout-parity.md and
file-format-parity.md ended up twice (an older and a newer version).
Each pair is now one row: the newer text, plus what only the older one
said (section note options #385; allowSpaceOfSameStyleInTable).

space after and the second's space before, as Word does by default. Word
adds them instead when the document's compatibility options include
w:doNotUseHTMLParagraphAutoSpacing. Measured in Word with five paragraphs
of 12 pt before and after: 24 pt between them with the option, 12 pt
without, the same in compatibility modes 14 and 15. A 60-page report with
the option lost 6 pt per paragraph, about 60 pt on its cover.
The option is read, laid out in the body and in boxes, and saved back.

A header or footer a section inherits (Same as Previous) keeps the
percentage widths of its tables relative to the section that defines it.
Measured in Word: a 100%-wide footer table defined by a portrait section
stays 451 pt wide, centred, on landscape pages that inherit it, and spans
the landscape width only when that section names the footer itself.
Paragraph alignment in the same footer follows the landscape page.
Found on a report whose landscape calculation pages drew their footer
table full width where Word draws it at the portrait width.

* Layout: an empty section mark stays on a full page
An empty paragraph that carries a section break, when the next section
starts on a new page, needs no room of its own in Word. Measured: 50 lines
filling a page, then that paragraph, then the next section makes two pages
in Word; WordCraft made three, the middle one blank. A plain empty
paragraph in the same place still moves on, in both.
Found after a landscape drawing page in a 60-page report.

* Tables: a row with less room than its minimum height moves on whole
Measured in Word with about 49 pt left on a page: a table row of eight
lines splits there, but the same row with an at-least height of 63.6 pt
goes to the next page whole, and so does one holding a nested table.
Without the height both split, as before. WordCraft split them all, so a
report's title row (a logo beside a small nested table) started at the
foot of its cover page.
