+/**
+ * dsh-sidebar-boost — composition bundle host entry.
+ *
+ * This package carries no logic of its own: it exists so that a single
+ * `dsh plugin add` installs and activates the whole sidebar suite. The
+ * activation rows live in `cordis.patch.yml` (each guarded against
+ * double-loading), and the browser-side UI comes from the `dsh.client`
+ * manifest field. This host entry is a minimal Cordis plugin so the bundle
+ * has something to load.
