+The SVG Interactivity panel (`window.panel {panel: "svgInteractivity"}`) reads `svgInteractivity.info {ids?}`:
+`events` (`[{event, script}]` in the panel's order, null where the objects differ), `files` (the linked JavaScript
+files) and `eventNames` (the 19 events the panel lists, from `onfocusin` to `onscroll`).
+`svgInteractivity.setEvent {event, script, ids?}` sets the JavaScript an event runs on the objects, replacing the
+event's script where they have one (an empty `script` removes it); `svgInteractivity.removeEvent {event, ids?}` and
+`svgInteractivity.clearEvents {ids?}` remove one event or all of them. Each is one undo step.
+`svgInteractivity.addFile {file}` and `svgInteractivity.removeFile {file}` link and unlink a JavaScript file (a path
+or a URL, kept as given without surrounding spaces); a document links at most 64 files. `ui.javascriptFilesDialog {}`
+opens the JavaScript Files dialog, whose Choose… puts a picked file in as a `file:///` URL. SVG export writes each event
+as an event attribute on the object's element (`onclick="…"`; with the SVG Tiny 1.2 profile it leaves them out with a
+warning) and each file as `<script xlink:href>`. SVG import reads the event attributes the panel lists and the
+`<script>` links back as text; it never reads a script file or runs a script, and leaves inline scripts and the links
+after the first 64 out with a warning. An unnamed `<g>` with event attributes of its own stays a group, apart from the object in
+it. The native format keeps the events and the files.

 - **UI:** Illustrator 2026 layout restyled to measured values:
   - Medium Dark theme, categorized and Advanced toolbars (a tool group's flyout opens on a right press, a long press or a press on its corner triangle), 35 pt document tabs, 33 pt panel tabs.
   - Hint bar, contextual task bar, 19 dock panels with ≡ menus.
+  - Window › SVG Interactivity attaches JavaScript to the selected objects' events (`onclick`, `onmouseover` and 17 more) and links JavaScript files to the document (Link JavaScript Files…); SVG export writes the events as event attributes and the files as `<script xlink:href>`, SVG import reads both back as text without running them, and the native format keeps them (`svgInteractivity.*`).
   - Numeric fields keep the pointer's pressed character as the text-drag start when movement exceeds the click threshold (#1326, in part); a completed focus click selects the unit too. 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. Short movements still counted as clicks can select all; that case remains open.
   - Unit fields and length strings take `%` in arithmetic: `3cm*50%` reads as 1.5 cm, and `50pt+25%` reads as 62.5 pt.
   - 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 and the Artboard tool show it).
