+/**
+ * Tauri adapter for {@link TemplateGateway} (L7).
+ *
+ * Commands use snake_case (Tauri convention); payload keys are camelCase
+ * (matching the backend DTO `#[serde(rename_all = "camelCase")]`), consistent
+ * with the other adapters in this directory.
+ *
+ * NOTE: The Tauri commands wired here are defined in the backend `app-tauri`
+ * crate and will be registered in a subsequent lot. This adapter is complete
+ * on the frontend side; the mock gateway covers tests and offline dev today.
