* Saved panel layout (display E10/E11 and resizing):
* - localStorage key llm-usage-panel-layout-{page}: { [group]: { order, hidden, sizes } };
* - order stores panel IDs after drag swaps; hidden lists hidden IDs;
* - sizes maps IDs to { span, height } set by the edit-mode bottom-right handle;
* - load removes obsolete IDs, appends new ones and rejects invalid sizes;
* unavailable storage, such as privacy mode, falls back to in-memory layout.
