Explain with highlit
CSP design is about reducing script execution freedom without breaking the app. I prefer nonces over unsafe-inline, keep the allowed source list tight, and roll policies out in report-only mode first. That gives teams a workable path from permissive front-end habits to something meaningfully safer.
