/**
 * Temporary in-memory fixtures used while el backend está apagado o
 * mientras se trabaja sin red. Se activan poniendo
 * `VITE_USE_MOCKS=true` en `.env`. Una vez el backend esté siempre
 * disponible, este fichero puede borrarse junto a las ramas
 * `if (USE_MOCKS) …` de `api.js`.
 *
 * Los objetos siguen la forma que la UI espera (post-normalización),
 * porque las funciones de `api.js` los devuelven directamente sin
 * volver a pasar por el mapper. Si en el futuro queremos imitar el
 * payload crudo del backend (`pub_year`, etc.), habrá que hacerlas
 * pasar por `normalizePublication` en el lado del servicio.
