+`plugins/blob.bar/` replaces the whole bar so the clock cannot be dragged out
+of the center. Omarchy 4 puts a drag-to-reorder handler on every bar module and
+persists the drop into `bar.layout`; once `blob.clock` leaves the center list,
+`centerAnchor` matches nothing and the center renders as a plain group. The bar
+config has no setting for this, so the only lever is `canReorder` in `Bar.qml`.
+The copy is two lines away from stock: a `anchored` property on `ModuleSlot`,
+and `canReorder` gated on it, which locks only the module named by
+`centerAnchor`. Every other widget still drags.

+Do not run `omarchy plugin clone omarchy.bar` to refresh it. That command copies
+the whole directory, including `widgets/`, whose manifests re-declare
+`omarchy.workspaces`, `omarchy.tray`, and four more ids that already exist.
+`Bar.qml` needs only `BarModel.js` - its widgets come from the host registry -
+so the copy is just `manifest.json`, `Bar.qml`, and `BarModel.js`. A bar is
+selected by `bar.id` in `shell.json` rather than by the enabled-plugin list, and
+it has no disabled state: you leave one bar by naming another.
