[bug\_fix] Attempting to use React Context Provider in a Server Component without 'use client'

Extract the Context Provider into a separate file marked with 'use client'. Import this wrapper into your Server Component \(e.g., layout.tsx\) and wrap the children. The children \(Server Components\) remain server-rendered while the Provider operates client-side. Root cause: React Context requires a client-side component tree to maintain the context value across re-renders; Server Components cannot hold client-side state or context.

Journey Context:
You create a ThemeContext in \`app/context.tsx\` with createContext and a Provider. You import this Provider directly into \`app/layout.tsx\` to wrap the entire app. Immediately, you get an error: 'createContext only works in Client Components.' You try adding 'use client' to layout.tsx, but that converts your entire root layout to a Client Component, breaking metadata exports and server rendering. You search for 'nextjs app router context' and find a specific guide in the Next.js docs. You realize you need to separate concerns. You move the Provider to \`app/components/Providers.tsx\`, add 'use client' there, then import Providers into layout.tsx and wrap \`\{children\}\`. The app works: the root remains a Server Component \(able to export metadata\), but the children are wrapped by a client-side Provider. You verify by checking that useContext works in deeply nested client components.
