Nuxtjs Guideline: DataFetching — Use lazy option for non-blocking fetch. Description: Defer data fetching for better initial load. Do: lazy: true for below-fold content. Don't: Blocking fetch for non-critical data. Good Example: useFetch('/api/comments', { lazy: true }). Bad Example: await useFetch('/api/comments') for footer. Severity: Medium.
