 SVG import keeps what the canvas edits live. `<pattern>` becomes a pattern swatch. A `<symbol>` with `<use>` becomes a
 symbol (named after its `data-name`, else its id) with an instance per `<use>`; a `<use>` that shows it differently

 - **Document Setup modal handoff:** Document Setup → Edit Artboards applies valid settings, closes the dialog and activates the Artboard tool. Pointer-click tests cover successful handoff, invalid settings, OK, Cancel and Undo in `dialogs/document_setup.rs`.
 - **Document Setup › Color:** a Color tab shows the document color mode (RGB Color or CMYK Color), a Convert to CMYK or Convert to RGB box for a mode change (cleared: the colors keep their numbers), and the RGB and CMYK profiles assigned to the document, with a working-space entry for none. OK runs `edit.assignProfile` and then `file.documentColorMode` with the dialog's other changes in one `command.batch`, and the document's changes are one undo step. An unchanged Color tab adds no color commands, and Cancel, or OK with nothing changed, records no undo step. A Color tab field with a value of the wrong kind is an error, and the dialog stays open. The tab is VectorCraft's own layout; File › Document Color Mode and Edit › Assign Profile… stay as they are. Tests in `dialogs/document_setup.rs`.
+- **Assign Profile's three choices:** the Assign rows of Edit › Assign Profile… (the Separations panel's Color Settings section) offer Don't Color Manage This Document, the working space of the document's color mode (Working RGB or Working CMYK, with its name) and Profile with the other profiles of that kind, as [Assign or remove a color profile](https://help.adobe.com/archive/en_US/illustrator/cs3/illustrator_cs3_help.pdf#page=150) lists them. They act on the profile of the document's color mode: an RGB document's RGB profile, a CMYK document's CMYK profile; the other model's profile stays as it is (VectorCraft's own rule; Document Setup › Color sets both). Picking the working space assigns its profile, which stays when the working space changes later. A choice the document already has runs nothing. Tests in `panels/separations.rs`.
 - **Canvas through the display's profile on Windows and X11:** Preferences › Performance › Use Monitor Profile for Canvas (on by default) converts the canvas's art, artboard paper and transparency grid from sRGB into the ICC profile of the display that shows most of the main window, after any proof, as the help page describes the monitor's profile translating the document's colors for the monitor ([the help page](https://help.adobe.com/archive/en_US/illustrator/cs4/illustrator_cs4_help.pdf#page=151)). Windows gives the display's default profile, and a display with Advanced Color on is left to Windows ([Microsoft Learn](https://learn.microsoft.com/en-us/windows/win32/wcs/advanced-color-icc-profiles)); X11 gives colord's profile for the output or the `_ICC_PROFILE` property. macOS converts the window itself, and a Wayland session stays sRGB. `ui.inspect` reports `displayProfile`. Tests in `color/src/cms/display.rs`, `ui-egui/src/display_profile.rs` and `canvas::tests::the_canvas_is_drawn_through_the_display_profile_while_the_preference_is_on`.
 - **Translucent art blended before the display profile:** with Use Monitor Profile for Canvas converting, translucent art and the anti-aliased edges of art over an artboard's paper, a colored artboard or the transparency grid are blended with it in sRGB and the blend is converted, so the monitor's profile translates the document's colors as they are composited ([the help page](https://help.adobe.com/archive/en_US/illustrator/cs4/illustrator_cs4_help.pdf#page=151)). The frame rendered whole, the part an edit renders again, the render worker's frame, the pan fill and the other windows' panes do the same; over the pasteboard and in Outline the art is converted on its own, and with no profile to convert into nothing changes. Tests `display_profile::tests::translucent_pixels_over_the_paper_are_blended_before_they_are_converted`, `the_transparency_grid_is_blended_cell_by_cell`, `the_backdrop_is_found_through_the_view` and `canvas::tests::translucent_art_over_the_paper_is_blended_before_the_display_profile`.
 - **Out-of-gamut warning after a profile change:** the out-of-gamut warning and its closest-color correction in the Color panel and Color Picker ([the help page](https://helpx.adobe.com/illustrator/using/adjusting-colors.html)) check the color against the document's assigned CMYK profile, else the working CMYK space, and update when Edit › Assign Profile… or Edit › Color Settings… changes that space or a loaded profile changes, without a change of color. Which CMYK space the warning uses is VectorCraft's own rule. Tests: `gamut_warning_follows_a_profile_change` and `gamut_warning_follows_a_profile_loaded_again` in `dialogs/color_picker/tests.rs`.
