+ * Controller-level vision behaviour (#1176).
+ *
+ * A Japa spec, not a plain `node:test` file: it constructs OllamaController,
+ * which imports '@adonisjs/core/services/logger' at module scope and therefore
+ * needs a booted app. Run with `node ace test unit`, not `npm run test:unit` --
+ * the latter is the plain-runner path used by the pure-function specs.
