   Window › Blend opens the Blend panel: Make, the selected blend's Spacing and Orientation (with no blend selected, the options new blends start with), Reverse Front to Back, Reverse Spine, Replace Spine, Expand and Release, each running its Object › Blend command. Make is dimmed until two or more objects are selected. Spacing and Orientation are dimmed until a blend or two or more objects are selected, and the other buttons are dimmed until a blend is selected.
   Objects on Path (#2545): a click with the Objects on Path tool (in Edit Toolbar's Modify section and the Blend tool's flyout; Object › Objects on Path › Attach and the context menu with two or more objects selected choose it) attaches the selected objects to the path clicked, open or closed, in an Objects on Path group with the path at its bottom. The objects go along the path column by column from left to right, spread evenly from its first anchor (the last one sits on the end of an open path), each turned to the path at its attachment point; Pivot and Rotate set where each one attaches and how far it tilts (`object.objectsOnPath.attach`, `object.objectsOnPath.options`). Editing the path moves the objects, an object moved on its own goes back, objects moved into or out of the group in the Layers panel join or leave the path, and Object › Objects on Path › Expand leaves a plain group. The group saves and reopens live and exports as plain art. The Space, Move All, Rotate All and Select/Move widgets, Detach, the tool's options dialog and the Properties panel section are missing.
 - **Paint and appearance (M3):**
+  - **CSS swatch libraries:** fractional linear and radial gradient stop positions are preserved, so nearby stops such as 12.5% and 12.890625% remain distinct instead of collapsing to 13%. Reference: [CSS Images 3 color stops](https://www.w3.org/TR/css-images-3/#color-stop-syntax). The original synthetic regression is `palette_io::tests::css_preserves_fractional_gradient_stop_positions` in `crates/color/src/palette_io.rs`. Scores and hours are unchanged.
   - **Swatches:** names follow the colour model and are unique; Swatch Options (process/spot, Global, Gray/RGB/HSB/CMYK/Web, live preview); editing a global or spot swatch recolours every linked fill, stroke and text run in one undo step; multi-select and delete with confirmation; New Swatch and New Color Group dialogs (a group from the selected artwork's colours); swatches in colour groups convert, separate and count like any other. The Swatches panel selects ranges and whole groups, has a find field, and drags swatches to reorder, regroup or paint art; Add Used Colors, Select All Unused, Merge, Ungroup and Sort by Kind; a CMYK document keeps applied colours in CMYK. Swatch libraries: nine generated colour libraries and five gradient libraries in a library panel, saved as `.vcswatches`, `.gpl`, swatch exchange (`.ase`) or CSS, and loaded from `.vcswatches`, `.gpl` and `.ase` files (`.ase` both ways: RGB, CMYK, Lab and Gray; global, spot and process; groups) and from color books (`.acb`, read only: the RGB, CMYK or Lab colors of a book such as a Pantone book a user owns, named with its prefix and suffix, spot unless it says process, #831); `swatch.library.copyToUser` copies a loaded library into the User Defined folder without replacing a file, and a file with the same extension and bytes as a User Defined library opens as that library. Tints of global and spot colours ("Name 40%") stay linked and separate as a percentage of their plate. Spot colours can be defined in Lab (Spot Colors options). A built-in [Registration] swatch prints on every plate.
   - **Colour:** a Color Picker (colour field, H/S/B/R/G/B channel slider, HSB/RGB/Lab/CMYK fields, hex, web-only snapping, out-of-gamut correction); the Color panel shows a selected colour in its own model and, with nothing selected, the new-art defaults in the mode picked last, which it keeps between sessions; Alt-click paints the other proxy; proxies look through groups and show "?" for mixed paint; Invert, Complement, Apply Last Color (`,`) and Apply Last Gradient (`.`) keep the colour model; every paint command feeds the recent colours. The Color Guide has 21 harmony rules, Steps and Variation options and Limit to Library. Adjust Color Balance (its Global mode shifts tints) and Saturate preview live; Edit Colors and Recolor also reach meshes, images and patterns. Recolor Artwork has colour reduction, five recolour methods, presets, Limit to Library, a colour-wheel Edit tab and Edit Color Group; a local Color Themes panel saves five-colour themes. Fill/Stroke chips open swatch and mixer popovers (the Properties panel has the Control bar's Fill and Stroke chips, Stroke link and weight spinner, with nothing selected too), panels have Illustrator's Window menu keys (Align Shift+F7, Transform Shift+F8, Pathfinder Cmd+Shift+F9, Layers F7, Character Cmd+T…; every panel can be given one in Edit › Keyboard Shortcuts), and Eyedropper Options pick up and apply chosen attributes (Alt and Shift+Alt, image pixels). An ICC CMYK profile converts straight into the RGB working space (not through sRGB, so a wider space such as Wide Gamut RGB keeps colours sRGB can't hold) with the colour settings' black-point compensation, on the canvas and in RGB exports alike (the built-in Generic CMYK compensates both ways, so RGB black separated to a rich black displays as black again). Fills and strokes can overprint (Attributes panel, Overprint Black options), and CMYK documents blend in inks on screen, in PDF and when flattening. Document Color Mode converts the art, symbols, pattern tiles and swatches through the colour settings: Gray stays Gray, RGB greys separate into four-colour greys and a rich black as Illustrator does, or go on the black plate only with `grays: "black"` (also for `document.open {colorMode}`).
     View › Proof Setup › Color blindness – Tritanopia-type turns Proof Colors on and proofs the canvas with the tritanopia simulation of Brettel, Viénot and Mollon (1997). The Separations Preview panel's Proof Setup list offers the same target (`view.proofSetup {target: "tritanopia"}`). Grays keep their value.
