  When the object the Blend tool picked first is deleted or undone away before the second click, the next click on an object picks that object first instead of doing nothing. Regression tests: `blend_tool_picks_again_when_its_first_pick_is_gone` in `meshblend.rs` and `the_blend_tool_picks_again_when_its_first_pick_is_deleted` in `tests/blendopts.rs`.
  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.
  With the Blend tool, Escape drops the object clicked first and stops the next click adding to the blend just made, so the next click picks a new first object; the document and the selection stay as they are. Regression tests: `escape_drops_the_blend_tools_first_pick` in `meshblend.rs` and `tests/blendopts.rs`.
-  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 and the Properties panel section are missing.

  Double-clicking the Objects on Path tool opens Objects on Path Tool Options ([Objects on Path](https://helpx.adobe.com/illustrator/using/objects-on-path.html)): the nine-point Pivot grid and the Rotate field set the attachment point and angle of the objects attached next, and groups already attached keep theirs; Reset puts the center and 0° back. Save keeps the options across tool switches and saves them with the preferences (`tool.setOption {tool: "objectsOnPath"}`).

  - **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.
