+ * Lexical's `dispatchCommand` matches command listeners by object reference, not
+ * by the string label. The package ships two independently-bundled entries — the
+ * browser build (`index` / `react` / `renderer`) and the node build (`headless`)
+ * — and if each entry inlined its own `createCommand(...)` call, dispatching a
+ * command obtained from one entry onto an editor registered by the other would
+ * silently no-op (different object identities, same label).
+ *
+ * By keeping every command in this one module — exposed verbatim through
+ * `@lobehub/editor/litexml-commands` and emitted as a shared chunk by both
+ * builds — a single object backs the command in any runtime, and the module is
+ * pure enough to be imported on the server without pulling in the DOM-dependent
+ * editor bundle.
