Identify the framework (Next.js pages router, app router, custom SSR). 2. Confirm where the nonce is generated (server) and how it reaches HTML. 3. Ensure: - CSP header includes style-src with the same nonce - styled-jsx style tags receive the nonce attribute ## Output expectations - Provide the minimal code changes needed in the appropriate files. - Include notes on where the nonce originates and how it propagates. - Avoid insecure CSP suggestions (do not recommend unsafe-inline). --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/andireuter) — claim your Tome and manage your conversions.
