With the web semantics tree on, a click on an empty part of the page focuses the GlobalShortcuts node, which sat above its Shortcuts, so key events never reached them and Ctrl+Z did nothing. The node now sits inside Shortcuts and Actions, under a debug label. - A weapon or lineup field edit whose target a teammate deleted changes nothing and gets no inverse, like every other kind. - Tests: deleting a link into a shared landing, undone, redone and undone again; a teammate deleting a lineup before its deletion is redone; the missing-target cases above; the shortcut node holding focus. - Removed what undo no longer reaches: the lineup graph cases in LineUpProvider.undoAction/redoAction and the provider and size-cache snapshot helpers. UtilityProvider's snapshot methods stay because custom_shape_color_test still calls them.

It now goes, unless a retained addition or deletion can bring the target back, like every other edit.
