  // The default platform app CSP can only be overridden by whitelisted apps.
  // This is a separate key from the top-level content_security_policy one since
  // we can't combine type restrictions with whitelisted ID restrictions. If
  // there is a need for additional whitelisted entries, the feature system
  // should instead be extended to support OR-ing of restrictions.
