Feature Flags
The demo provides several feature flags that you can use to simulate different
scenarios. These flags are managed by flagd, a simple
feature flag service that supports OpenFeature. Flag
values are stored in the demo.flagd.json file. To enable a flag, change the
defaultVariant value in the config file for a given flag to “on”.
