* #2617: centre equation-array rows without &
A row with no alignment mark sat in the first column and was right-aligned
to it, widening that column and pushing the aligned rows right (Word's
"First Property of Radicals" case equation). Word centres such a row in the
array; it no longer widens the aligned columns.

* #1500: shape fills keep gradients and transparency (model, DOCX read/write)
A shape's, text box's and canvas's fill is now a `Fill` (solid with
transparency, or a gradient kept as the file states it) instead of one
opaque colour, so gradients and transparency survive opening and saving.
- doc: `fill::Fill`/`Gradient` with sanitizing for hostile input; `.json`
keeps writing opaque solid fills as `[r,g,b]` and reads both forms;
`ShapeExtra::outline_fill` keeps an outline gradient.
- docx read: `a:solidFill` with `a:alpha`, `a:gradFill` (stops, `a:lin`,
`a:path`/`fillToRect`, `tileRect`, `rotWithShape`, `flip`), theme fill
styles through `a:fillRef` 1-999/1001+ with `phClr`, `a:grpFill`,
`satMod`, outline gradients, VML `v:fill` gradients and opacity, canvas
backgrounds.
- docx write: `a:solidFill` + `a:alpha`, `a:gradFill` as read.
- engine/docbin/layout: call sites; drawing still uses the main colour
(next commit draws gradients).

* #1500: draw shape gradients and transparency (layout, render, PDF)
- layout: WordArt's paint becomes a shared `display::Paint` (solid,
linear, radial); `paint_for` lays a fill over the shape's frame
(linear at its angle, `scaled` honoured; path gradients circular from
their focus to the farthest corner). Shapes, freeforms and canvas
backgrounds use it.
- render: one `set_paint` for shapes, paths and WordArt; radial
gradients; soft edges fade the real fill.
- pdf: axial and radial shadings with per-stop opacity.
- Review fixes: nested groups without a fill pass theirs on to
`a:grpFill`, text-box contents don't take a group's fill, `phClr`
transparency only on `phClr` colours, VML focus ends consistent and
opacity clamped, `rotWithShape`/`scaled` written only when set,
Shape Outline clears an outline gradient, shared stop sanitizing.
- docs: file-format, layout parity, gaps #1, roadmap progress log.

* #1500: shape.fill sets transparency and gradients on every selected shape
- shape.fill (now cmd/shape_fill.rs) takes {"color", "transparency"?} or {"gradient": {stops,
type, angle, focus, rotateWithShape}}; a colour alone keeps the transparency; values are
sanitized; applies to every selected shape, text box and canvas as one undo step.
- Formatting (shape.fill, shape.effects) keeps a Shift+click multi-selection, as in Word.
- view.formatShapePane toggles the Format Shape pane.
- Session::undo_mark/merge_undo_since: a pane drag that applies as it goes undoes in one step.
- Helpers for the pane: params(fill), stop add/remove/move, directions, variations and
presets (variation and preset colours provisional until compared with Word).
- Catalog: Shape Fill Gradient, Format Shape Pane.

* #1500: Shape Fill › Gradient and the Format Shape pane
- Shape Fill › Gradient: No Gradient, Light and Dark Variations of the shape's colour, More

- Format Shape pane (right): No fill / Solid fill (colour, transparency) / Gradient fill
(presets, type, direction, angle, stops bar with add/remove/drag and arrow keys, per-stop
colour, position, transparency, rotate with shape). Drags preview live, one undo step.
- Right-click › Format Shape… on shapes, text boxes and canvases.
- Gradient swatches have accessible names; new labels translated (own wording, clean room).

* #1500: Gradient variations, starting gradient and directions as Word 365 does them
Observed in Word 365 (behaviour and values only):
- Shape Fill › Gradient: a No Gradient swatch, then 13 Light and 13 Dark Variations in a
grid five wide, in Word's order; light stops tinted 66/44.5/23.5% with saturation ×1.6,
dark shaded 30/67.5/100% with ×1.15; linear ones scaled; corners with their tile rectangle.
- Format Shape › Gradient fill starts from the theme's first accent (four stops, 0/74/83/100%).
- Corner directions in the pane get the same tile rectangle; Add/Remove sit by the stops bar.
- shape.fill carries "scaled" and "tile"; docx exports color_modified (lumMod, lumOff, tint,
shade, satMod) so variations use the reader's own colour maths.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* #1500: review fixes for the shape fill ribbon controls
- Gradient variations are built from the colour the shown variation came from, so picking
variations in turn, or No Gradient, doesn't drift the colour.
- A drag's undo mark is forgotten while the Format Shape pane is closed (a stale mark could
merge later undo steps).
- Dragging on the stops bar away from a handle no longer moves the selected stop; the arrow
keys are taken by the bar (no focus moves or shape nudges).
- Direction and Type changes keep a linear gradient's "scaled" and an imported tile
rectangle; only a corner direction sets its tile.
- Colour modifiers (lumMod, lumOff, tint, shade, satMod) live on Rgb in the doc crate, shared
by the DOCX reader and the gradient builders.
- Previews build their stop list once per swatch, not per vertex.
- Translations for the pane's hint, direction and preset names.

* #1500: adapt to main: caret contrast samples gradient fills; upstream tests use Fill/Paint
- Paint::at gives a paint's colour and opacity at a point; the caret's background sampling
(#299) uses it for shape fills, now gradients or transparent, and the Format Shape
previews use it too.
- Upstream tests (#886 shapes survive saving, render) build fills as Fill/Paint.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* #1500: adapt to main after the rebase: VML presets, rounded corners, new catalogs
- vml_fill takes the shape's shapetype: a VML preset shape (#1377) takes its fill, opacity and
gradient from its shapetype when it states none of its own, as it already took its colour.
- Rounded-rectangle corners (#1476) and the gradient paints meet in render, PDF and the caret's
background sampling; ShapeExtra keeps both `corner` and `outline_fill`.
- Tests that landed on main since build fills as Fill/Paint (VML presets, cover pages, VML
freeforms, path arrowheads, PDF and render shapes).
- The 40 Shape Fill / Format Shape strings in the hr, ko, sv and vi catalogs, which main
gained since.

* #2048: text above a float's anchor wraps around it
A floating object joined the page's wrap areas only when layout reached
its anchor paragraph, so paragraphs above the anchor ran behind a picture
placed higher up the page (fixed on the page, or moved up from its
paragraph). Layout now notes such floats and lays the pass out again
(at most 3 times) with their wrap areas known from the page's start.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* #2048: early-float wrap settles when the anchor moves to the next page
Review follow-up. Rewrap passes add to the wrap areas pages start with
instead of replacing them, and a pass is done when every float found
above its anchor sits inside the room its page started with. A float
whose wrap pushes its own anchor onto the next page has no fixed point;
the first page keeps the room and the float goes with its anchor, so
the passes no longer swap between the two pages. The last allowed pass
moves any float still not covered into its seeded room, or down to its
paragraph's top, so the returned layout never has text under it.
Tests: the reviewer's page-boundary case, and a last pass with nothing
seeded keeping floats clear of earlier text.

* #1740: triple borders draw as three lines on screen and in PDF
Triple borders (tables, paragraphs, the ### AutoFormat line) were drawn as
double lines. Layout now emits a Triple stroke; the renderer and the PDF

table borders get three side-by-side lines too.

* 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.
Co-Authored-By: Claude <noreply@anthropic.com>
* 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

Only a breakable space counts now. The parity checklist lists the rule
on its own row as untested against Word.

A bullet stored as a private-use code (U+F0xx) in a font that isn't

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

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.
