Control bar: the Artboard tool shows the active artboard's preset, name, X, Y, W and H

With the Artboard tool in use, the Control bar showed Move and Scale
Artwork with Artboard and then the object controls (Fill, Stroke,
Opacity and the rest). The reference app's help lists the Control
panel, with the Artboard tool, among the places to add, delete,
rename, resize and position artboards, set their orientation and
reference point, and open Artboard Options.

While the tool is in use, the Control bar now shows the active
artboard's controls in place of the object controls: Preset, Portrait
and Landscape, New Artboard, Delete Artboard, the Name field, Artboard
Options, Rearrange All Artboards, the Transform link, Move and Scale
Artwork with Artboard, and the reference point with X, Y, W and H and
the Constrain Width and Height Proportions link. Each control runs the
command its Properties or Transform panel counterpart runs, and the
reference point is the one the Transform panel uses. In an 800-point
window the controls up to the Transform link fit, the two artwork
options show as their boxes with their names in tooltips, and the link
opens the position and size in a popover, as it does for objects.

 - **Rulers (#1212):** drag the intersection to preview and set a document zero point, or double-click it to reset to the active artboard's top-left. Transform, Properties and Control X/Y fields measure from it and convert entered positions back to absolute command coordinates. The origin survives every native format version and compression; geometry, guides and patterns stay in place. Global/artboard mode switching and video rulers remain separate.

 - **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`.
+- **Control bar with the Artboard tool:** while the Artboard tool is in use, the Control bar shows the active artboard's controls in place of the object controls: Preset, Portrait and Landscape, New Artboard, Delete Artboard, the Name field, Artboard Options, Rearrange All Artboards, the Transform link, Move and Scale Artwork with Artboard and, while the bar has room, the reference point with X and Y, and W and H with the Constrain Width and Height Proportions link. Each runs the command its Properties or Transform panel counterpart runs (`artboard.setProps`, `artboard.new`, `artboard.delete`, `tool.options {tool: "artboard"}`), and the reference point is the one the Transform panel uses. In an 800-point window the controls up to the Transform link fit, Move and Scale Artwork with Artboard show as their boxes alone with their names in tooltips, and the link opens the Transform panel with the artboard's position and size. Pointer and key tests in `panels/artboards.rs` cover the controls, W about the reference point, the orientation and the name.

 - **Edit Artboards in Properties:** the active artboard's name is a field. Typing a new name and pressing Enter or clicking elsewhere renames that artboard in one undo step, as the Artboards panel's rename does (`artboard.setProps {index, name}`); pressing Escape or leaving the field empty keeps the old name. A click on the Artboard Options icon beside the field opens Artboard Options for the active artboard, as double-clicking the Artboard tool's button does (`tool.options {tool: "artboard"}`). Pointer and key tests in `panels/properties.rs` cover both. Public references: [Resize artboards](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/add-edit-artboards/resize-artboards.html) and [Create and add new artboards](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/add-edit-artboards/add-new-artboards.html).
 - **Artboard Escape routing:** Escape leaves Artboard editing for Selection; during a drag it first cancels the gesture. Headless egui key events cover idle Escape, active-drag cancellation and a subsequent Escape in `tests_distortkeys.rs`.
 - **Artboard deletion keys:** Delete/Backspace delete selected boards in one Undo step, retaining the original first board in the current order when all are selected, as in the public [Delete artboards guide](https://helpx.adobe.com/illustrator/desktop/create-manage-artboards/add-edit-artboards/delete-artboards.html). The last board and active drags stay protected; neither key clears selected artwork. Headless shortcut regressions in `tests_distortkeys.rs` cover reordered boards, artwork, saved state and Undo/Redo.
