A/B testing

Before shipping a feature with experiment support, verify the A/B testing configuration is correct.

Pre-ship verification

1. Variant assignment works — the ExperimentProvider interface (variant(key) -> String) returns valid variants for all experiment keys used by the feature.
2. Default variant is safe — when the experiment provider is unavailable or returns an unknown key, the feature SHOULD fall back to the control (default) variant.
3. Debug panel override works — verify the debug panel can force each variant locally for QA testing.
