Nuxt SSR vs SPA: what are the trade-offs for performance and SEO?

**SSR** renders HTML on the server, improving first paint and SEO for content-heavy pages. **SPA** renders mostly on the client, which can be simpler but may need extra work for SEO and initial load. **Trade-offs:** - SSR: more server complexity, hydration cost - SPA: potentially slower initial content, but simpler infrastructure In practice, use SSR/SSG for SEO pages and SPA behavior for app-like interactions.
