1. Production Architecture: Per-Request Cryptographic Nonce Generation & Violation Report Telemetry

import secrets

def build_strict_csp_header() -> tuple[str, str]:
    nonce = secrets.token_base64(16) if hasattr(secrets, "token_base64") else secrets.token_urlsafe(16)
    policy = f"default-src 'self'; script-src 'self' 'nonce-{nonce}' 'strict-dynamic'; object-src 'none'; base-uri 'self';"
    return nonce, policy
