Drop the investor concern entirely

It was a worked example of the empathic pattern, not a feature: every
alternative should be empathic, informative, and helpful - information
that gives an answer, not necessarily a path to choose. The pattern
stays (voice rules, README); the investor pages, aggregate, review
alternative, and front-page gateway go. The investors KV bucket and
its test records linger in NATS unreferenced - purge at leisure.
