+The blog plugin exposes standalone getter and mutation functions for server-side use cases. These bypass the HTTP layer entirely and query the database directly — no authorization hooks are called, so the caller is responsible for any access-control checks.
 
 ### Two patterns
 
 **Pattern 1 — via `stack().api` (recommended for runtime server code)**
 
-After calling `stack()`, the returned object includes a fully-typed `api` namespace. Getters are pre-bound to the adapter:

 ## Static Site Generation (SSG)
 
 `route.loader()` makes HTTP requests to `apiBaseURL`, which silently fails during `next build` because no dev server is running. Use `prefetchForRoute()` instead — it reads directly from the database and pre-populates the React Query cache before rendering.
