// The client-side configuration for the origin trial framework can be
// overridden by an installed component named 'OriginTrials' (extension id
// llkgjffcdpffmhiakmfcdcblohccpfmo. This component currently consists of just a
// manifest.json file, which can contain a custom key named 'origin-trials'. The
// value of this key is a dictionary:
//
// {
//   "public-key": "<base64-encoding of replacement public key>",
//   "disabled-features": [<list of features to disable>],
//   "disabled-tokens":
//   {
//     "signatures": [<list of token signatures to disable, base64-encoded>]
//   }
// }
//
// If the component is not present in the user data directory, the default
// configuration will be used.
