      Defense in depth alongside the worker-side strip in sandbox-worker.js:
        - script-src 'unsafe-inline' is unavoidable because the theme bootstrap
          inline script below must run before paint to avoid a flash.
        - connect-src 'self' blocks page-side fetch to any non-origin URL.
        - worker-src 'self' blocks blob: sub-workers (paired with Bug #5 strip).
        - frame-ancestors 'none' prevents clickjacking via iframe embedding.
      Note: the meta-tag CSP does NOT apply to the Web Worker (it needs
      response headers for that), so the worker can still use `new Function`
      to compile generated code.
