/// WILL be rendered on the seed + verification screens. Those beats run inside
/// `blindfold`, which records the span into the driver output. `capture.sh`
/// refuses to promote a master to the publishable directory while any
/// blindfold span is uncut, so the frames cannot reach a store listing by
/// accident.

/// The wallet created here is throwaway. Never fund it.
