Pixel/point, plain and optional fields are regression-tested in both directions, before/after focus, with replacement text; keyboard focus, double-click, arrows and wheel keep their prior behavior. Native egui input confirms partial replacement gives 17 px instead of 700 px, one Undo/Redo, window captures and an exact saved-document read in a separate CLI process. A focus click released more than 1 pt from its press keeps the caret, and a tap within 1 pt still selects all (#6659; short-drag and jitter-tap regressions in `tests/numfields.rs`).

   - The contextual task bar's handle drags it anywhere on the canvas (kept whole on it as the window resizes); unpinned it keeps that offset as it follows the selection, and its More Options menu hides it, pins its position across selection changes (`window.taskBar.pin`), resets it under the selection (`window.taskBar.reset`) and shows the Properties panel. As in Illustrator the position isn't kept across launches. Not done: the bar's variants for other tools (only the selection tools, the Type tools and the Artboard tool show it).
