Dynamic Imports for Heavy Components

Use next/dynamic to lazy-load large components not needed on initial render.

Incorrect (Monaco bundles with main chunk ~300KB):

function CodePanel({ code }: { code: string }) {
  return 
}

Correct (Monaco loads on demand):

const MonacoEditor = dynamic(
  () => import('./monaco-editor').then(m => m.MonacoEditor),
  { ssr: false }
)

function CodePanel({ code }: { code: string }) {
  return 
}
