The Paragraph panel menu's Justification… was a disabled stub, and justified
lines stretched word spaces between fixed limits (80% to 150%).
Each paragraph now has Justification options: Word Spacing, Letter Spacing
and Glyph Scaling (Minimum, Desired, Maximum, in percent), Auto Leading and
Single Word Justification. Desired applies to every line; a justified line
fills its measure with word spacing first, then letter spacing, then glyph
scaling, each within its range, and past them its word spaces take the
rest. The Every-line Composer scores lines by that flexibility. Auto
Leading sets the leading of characters whose leading is Auto. A justified
line holding one word is spread between its letters (Full Justify) or
aligned left, centre or right.
The defaults are the documented ones (80/100/133, 0/0/0, 100/100/100, 120,
Full Justify), saved only when they differ. Because the default maximum
word spacing is 133%, justified paragraphs break differently than before;
the Every-line Composer's second pass is now unbounded for justified text
(it used to give up past four times the stretch and fall back to the
Single-line Composer, which the narrower default range would make common),
and lines that can't stretch at all are still refused.
text.setFormat takes wordSpacing, letterSpacing, glyphScaling ([min,
desired, max] or {min?, desired?, max?}), autoLeading and
singleWordJustification; Minimum ≤ Desired ≤ Maximum must hold or nothing
changes. Paragraph styles carry the options (New and Redefine capture
them), and Reset Panel resets them. Justification… opens a dialog
(ui.justification) with Preview; OK is disabled while a row is out of
order. Live SVG text places characters the options move, and a glyph that
Glyph Scaling scales is stretched to its width; PDF uses the glyphs'
transforms. Vertical type isn't glyph scaled; type on a path doesn't use
the options.

SVG export wrote each style run of a line of live text as one <tspan>
and positioned the text again only after tabs and, on justified lines,
after word spaces. A viewer then spaced the characters inside the
<tspan> with the font's own advances, so it lost the letter gaps of a
Justify All line without word spaces, the gaps between the characters
of a justified Japanese line and the spacing that a Mojikumi Set
changes. On justified lines, the textLength of horizontally scaled type
also took in the justification space after it, so a viewer stretched
the glyphs into that space.
On a line that is justified or set with a Mojikumi Set, text_lines now
lays the text out again as point type without the Mojikumi Set to get
the advance a viewer gives each character. Each character that the
layout draws away from where a viewer would draw it starts a new
positioned <tspan>, and textLength and line anchors use the viewer's
widths. The last character of a horizontally scaled <tspan> takes its
width without the font's kerning against the next character. Other
lines, and lines written with Fewer <tspan> Elements, are written as
before.

Adds the Character panel menu's Digits option (with the Middle Eastern /
Indic options, beside Paragraph Direction in the Paragraph panel) as a
character attribute: CharStyle::digits, saved only when set, with
text.setFormat {digits} and text.setRangeStyle {id, start, end, digits}
("default" | "arabic" | "hindi" | "farsi"; a bad value is an error).
Shaping draws every digit of the Western, Arabic-Indic (U+0660–U+0669)
and Eastern Arabic-Indic (U+06F0–U+06F9) sets in the chosen system,
whatever was typed, before font fallback, so a font without the
Arabic-Indic digits gets a fallback for them. The text, its clusters,
the caret, selection and search stay as typed, as with All Caps; SVG
export writes the digits as drawn.
Catalog rows for Digits, Arabic, Hindi and Farsi in the ten translated
languages. Docs: docs/mcp.md (Digits), type-parity.md (digit types
done; Character Direction, kashidas, composers and the split caret
still missing), target-app-parity.md and gaps.md.
Behaviour from the public documentation (a character-level option with
the values Arabic, Hindi and Farsi in the Character panel menu):

Tests: doc (the mapping and serialization), text (glyphs of "page 3" in
Hindi/Farsi equal the typed Arabic-Indic digits' on the typed clusters;
skips without a font covering the three sets), engine (setFormat,
setRangeStyle, undo, error), svg (digits written as drawn), ui-egui
(the menu shows with the Indic options).

A character attribute (Character panel menu with the East Asian options;
`text.setFormat` / `text.setRangeStyle {proportionalMetrics}`), saved only
when on. In horizontal type it applies `palt`; vertical type sets as before
until the vertical shaping change (`vpal`) follows.
Line-end Punctuation Half Width takes nothing more off the punctuation
`palt` re-spaced (the flush opening bracket, consecutive punctuation, the
line-end half width): the segment is shaped once more without `palt`, and
the glyphs whose advance differs are marked. Punctuation the font leaves
full width is trimmed as before. SVG writes `"palt" 1` with the
character's other features.

Document symbols placed inline in a run of type (beyond Illustrator; like
InDesign inline anchored objects): TextRun.inline holds the symbol, scale and
shift; the run is one U+FFFC laid out as a glyph sized to the art, centred on
the cap height. text.insertInline and Type > Insert Inline Symbol; editing
keeps the graphic whole; canvas, SVG (<use>) and PDF draw the art; Create
Outlines turns it into a symbol instance.
Each paragraph has its own alignment, indents, spacing, hyphenation, tab
stops and paragraph style (TextObject.paras; para stays paragraph 0's, so
old files and readers work). Layout, editing (split/merge), threads, the
Paragraph/Tabs/Paragraph Styles panels, ranged text.setStyle/setFormat/
tabs/paraStyle.apply, SVG export/import and the fuzzers follow.
Area Type Options > Align: Top / Center / Bottom / Justify (AreaOptions.verticalAlign,
LayoutOptions.vertical_align). Each row/column cell is aligned on its own; rectangular
cells shift their lines, other frames and text wrap reflow until settled without
losing text. Justify shares the leftover space equally between line gaps. Area Type Options
shows Align and First Baseline as dropdowns (the parameter dialog's choices table).
Every laid-out line of type is written at its own position (wraps,
indents, tabs, hyphenation and all caps as on the canvas): a positioned
tspan per style run and, on justified lines, per word. Centred and
right-aligned lines are anchored at their centre or right end, so they
stay aligned in a viewer whose font differs. Leading comes from the
layout's baselines, baseline shift is written as dy, horizontal scale as
textLength, vertical scale as the size, tracking and manual kerning as
letter-spacing. The fewerTspans option (engine and dialog) writes one
positioned tspan per line.
