Edge Deploy Frontend: build, runtime, Cloudflare Workers, Vercel Edge, image opt, preview envs, atomic deploys

Trilha sobre build e deploy de apps frontend modernos: do build output (static, SSR, SSG, ISR, edge) ao runtime (Node, serverless, edge), passando por Cloudflare Workers (V8 isolate, KV, R2, D1, Durable Objects), Vercel Edge (Edge runtime, ISR, on-demand revalidation), image optimization (Next/Image, Cloudflare Images, formato moderno, lazy loading), preview environments por PR (ephemeral envs, branch URLs), e atomic deploys com cache (blue/green, cache headers, invalidation, rollback). Cobre o workflow completo de 'codigo em producao'.
