A CMYK document that shows transparency is drawn once per ink plane
(complemented C, M, Y; complemented K as a grey) so every blend mode,
opacity, group, knockout and effect composites inks, PDF-style; the
planes' inks are shown through the working CMYK profile (cached 4-D XYZ
table). Cyan multiplied over magenta now shows C100 M100. Opacity masks
keep screen luminance; RGB colours and placed images are separated
first. RGB documents and opaque CMYK documents keep the screen-colour
path.
PDF export of CMYK documents writes its transparency groups with
/CS /DeviceCMYK (luminosity mask groups stay RGB) and puts top-level
transparency in a non-isolated page-wide group so it blends in CMYK too.
Flatten Transparency composites CMYK documents ink by ink and makes CMYK
regions. Non-separable modes no longer give NaN for greys.

Recolor Artwork keys colours by identity (model and exact values), so CMYK
colours stay CMYK and lookalikes stay apart. recolor.reduce groups the
selection's colours into rows (k-means in Lab, weighted by use; tints of a
global swatch share its row) with Preserve White/Black/Grays and Limit to
Library; recolor.apply maps rows by Exact, Preserve Tints, Scale Tints, Tints
and Shades or Hue Shift; recolor.randomize shuffles or varies new colours.
The dialog has Assign (rows with merge, separate, exclude, randomize, method,
library) and Edit (hue/saturation wheel with linked or unlinked handles,
brightness, harmony rules) tabs, and Edit Colors gains Recolor with Preset
(1/2/3 Color Job, Color Library). Colour parameters accept colour keys.

Colours gain a CIE Lab model (`Color::Lab {l,a,b}`, serde tag `lab`), handled through the
CMS (display, separation, conversions, gamut), tints (toward paper white), keep_model, harmonies,
recolouring, blends, Info and the Color panel. Swatch Options gets a Lab mode
(`swatch.edit {mode: "lab"}` / `{color: {l,a,b}}`), and colour params accept `{l,a,b}`.
Swatches panel → Spot Colors… (`ui.spotColors`, dialog `spotColors`) runs `swatch.spotOptions
{useLab}` (Document.spot_use_lab, default on): Lab spot colours show and separate from their Lab
values, or art linked to them takes their working-CMYK equivalents, as one undo step. PDF export
writes Lab spot inks as Separation spaces with a Lab alternate (tint function from paper white),
or a DeviceCMYK one with CMYK equivalents.

[Registration] is a built-in swatch that prints 100% on every plate: Separations
Preview shows it on each process and spot plate and PDF export writes it as
/Separation /All. It can't be edited, moved, duplicated, merged or deleted;
swatch.list shows it after None and the Swatches panel applies it as a swatch.
Object > Create Trim Marks strokes the marks in Registration and marks every
artboard when nothing is selected ({style?, allArtboards?}). The preference
japaneseCropMarks (General) switches to Japanese marks: double lines at the
trim and bleed edges plus centre marks. Effect > Crop Marks (cropMarks) is a
live effect whose marks follow the object; rendering, SVG/PDF export and
Expand Appearance draw them. The mark geometry lives in doc::marks.

Object > Expand… opens a purpose-built dialog (Object, Fill and Stroke
checkboxes, disabled when the selection has nothing for them; Expand
Gradient To: Gradient Mesh or Specify N Objects, default 255). Every
option now does something:
- Object: type to outlines, live shapes to paths, effects baked.
- Stroke: strokes outlined into filled paths.
- Fill: linear/radial gradient fills become N solid rectangles or
concentric ellipses, or a gradient mesh with lines where the colour
changes, inside a clip group shaped like the object; freeform
gradients become a mesh shaped like the object. Colours keep their
stops' colour model. With Fill off gradient fills stay live.
object.expand {} defaults match the dialog (stroke now defaults on);
new query object.expand.info and UI command ui.expandDialog.
Create Gradient Mesh on a gradient-filled object takes the colours the
gradient paints at each point (GradientMesh::for_path_with, from_grid,
highlight).

A colour linked to a global or spot swatch keeps a tint (Paint::Solid.tint, 1 by default and
left out of files at 100 %): paint.setFill/setStroke {swatch, tint} apply the swatch at that
percentage, swatch edits recolour every linked colour at its own tint, and Color::tinted
resolves it (CMYK and Gray inks scale, RGB mixes toward white). swatch.new saves a tint as a
tint swatch ("Ink 40%") linked to its base. Spot tints separate as that percentage of their
plate (Separations Preview, PDF Separation value) instead of an ink-ratio guess. Adjust Color
Balance's Global mode (tint) shifts the tints of linked colours. The Color panel shows Tint
mode (the swatch chip, its name and a T slider) for linked colours; the Swatches panel
highlights the tint swatch in use. Gradient stops get the same link and tint fields (the
swatch walks cover them), so GradientStop is no longer Copy.

Freeform gradients carry their own points (colour, opacity, spread) and lines
(Catmull-Rom curves through points), blended by inverse-distance weighting
from each disc of pure colour. paint.editGradient {kind: "freeform", mode?}
places 4+ points inside the shape, coloured along the stops (which follow the
points' colours). The renderer samples the field on a cached colour grid
drawn as an image paint clipped by the fill or stroke. Moves, transforms,
box rebases and warps move the points; old files load unchanged.

Window > Swatch Libraries > Gradients lists five generated gradient
libraries (Spectrum, Sky, Neutral incl. fades to transparent, Duotone,
Radial Glows); the library panel's menu lists them too.
Swatch Options on a gradient swatch shows its name and the gradient; OK
renames it. Alt-dropping an edited gradient (or a colour) on a swatch of its
kind in the Swatches panel replaces it, via swatch.edit {paint}.

Save Swatch Library… (Swatches panel menu, libraries menu, Window menu)
opens a dialog: name, format and destination. .vcswatches is lossless JSON
(colour models, global, spot, gradients, groups), .gpl an RGB palette with
groups as comment headers, CSS custom properties with escaped names.
Libraries saved to the user library folder show under User Defined.
Other Library… (and opening a .vcswatches/.gpl file) loads a library or
another document's swatches into the library panel.
Commands: swatch.library.save {path?, format?, names?, name?, user?}
(no path returns {data}), swatch.library.load {path?|data?|dataBase64?,
name?}; UI: window.swatchLibrary.other, ui.saveSwatchLibrary (dialog
saveSwatchLibrary), window.userSwatchLibrary1..10.

Window > Swatch Libraries and the Swatches panel's library button open a
read-only, floating library panel (thumbnail and list views, find field,
libraries menu, previous/next arrows). Clicking a swatch adds it to the
document and applies it as one undo step; Shift/Cmd-clicks select swatches
and groups for Add to Swatches. Default Swatches restores missing defaults.
Libraries are computed in code (OKLCH, rounded to 8-bit sRGB): Web Safe 216,
Grays and Neutrals, Earth Tones, Skin Tone Ramps, Pastels, Brights,
Metallic Gradients, Perceptual Scales, Harmony Sets.
Commands: swatch.library.list, swatch.library.get, swatch.library.add
{library, names?, apply?, focus?}, swatch.resetDefaults {replace?};
UI command window.swatchLibrary {library}.

color::blend gains blend_rgb (the 16 blend functions, with the 0.3/0.59/0.11
luminance of the non-separable modes), composite (source-over with blending)
and the shared opacity-mask luminance weights. Exported SVG masks take
luminance from sRGB values (color-interpolation="sRGB"), as the canvas does.
Tests: a per-mode table on the canvas (object, fill and group blend modes,
within 1/255; Exclusion 2/255 in the rasteriser's 8-bit pipeline), the same
table through SVG export rendered by resvg, clip and invert masks against the
canvas, and every mode's PDF name read back.

The harmony rules (Complementary 1/2, Split Complementary, Left/Right Complement, Analogous 1/2,
Monochromatic, Shades, Triad 1-3, Tetrad 1-3, Compound 1/2, High Contrast 1-3, Pentagram) live in
the color crate with our own math, base colour first. The variation grid moves there too
(`harmony::Guide`): a row per harmony colour with the colour in the centre column, shades/cool/muted
to the left and tints/warm/vivid to the right, 1-20 steps and a variation amount.
- `color.harmony {color, rule, steps?, variation?, amount?}` query returns {rule, colors, grid}.
- The panel keeps its base colour until "Set base color" takes the current one; Shift/Cmd-click
selects several cells and Save Colors as Swatches saves them (`swatch.new {colors}`, one step).
- Color Guide Options dialog (`ui.colorGuideOptions`, kind `colorGuideOptions`) with a preview row;
the options persist in `UiState::color_guide`.

A CMYK document (file.new {colorMode: "cmyk"}, Document::new_with_mode)
starts with CMYK default swatches (default_swatches(model)), and RGB
colours and gradient stops applied to it are stored as CMYK (Gray stays
Gray) unless paint.setFill/setStroke get keepModel; the Color panel keeps
the model picked on its sliders. RGB documents keep colours as given.
Harmonies and Color Guide variations keep the base colour's model, Recolor
Artwork the replaced colour's, and Edit Colors blends between models take
the document's, through a shared Color::in_model / keep_model.

The eyedropper (`appearance.copyFrom`), `graphicStyle.new` and `graphicStyle.apply` move placed gradients so they
sit at the same place relative to each target's bounds (type: its layout box in text space) instead of where the
source had them; the paint defaults take the gradient unplaced, so new art fits it. Model: `GradientGeom::rebase`
/ `GradientPaint::rebase` (color), `Appearance::rebase_gradients` (strokes relative to their inflated boxes) and
`GraphicStyle::unit_box`: new styles store placed gradients in unit-box space; styles from older files keep
document coordinates and apply as before.

The Gradient panel gains the Fill/Stroke proxy, a thumbnail menu of the document's gradient swatches with Save to
Swatches, Angle and Aspect Ratio fields with preset menus (the shared spin field), Show/Hide Options, and a stop
colour row whose eyedropper samples the next colour clicked on art into the selected stop (Eyedropper tool option
`stop`, `paint.sampleColor {stop}`). On the slider a selected midpoint diamond shows and sets its midpoint in
Location, double-clicking a stop opens the shared stop popover, Alt-drag copies a stop and Alt-dropping it on
another swaps their colours (`swap_stop_colors`), and a dropped colour swatch adds or recolours a stop. Clicking a
stop no longer falls through to the add-stop strip. Swatch tiles and the gradient thumbnail drag onto art, which
paints the object under the pointer through `paint.setFill`/`paint.setStroke {ids}`. The panel, the popover and
the Color panel share one stop-writing helper.

The wide-gamut RGB working space is now "Wide Gamut RGB (1998 primaries)";
its old name still resolves everywhere (cms::profile / canonical_name,
Color Settings, Assign Profile, documents and settings saved earlier).
The Effect menu section is "Vector Effects", stroke width profiles are
Lens / Taper Start / Taper End, dash, arrowhead-tip and gradient-on-stroke
tooltips are reworded, the Window library submenus hold neutral disabled
placeholders until the generated libraries land, and the Swatches menu
offers "Save Swatch Library…" (disabled).
