Funnel

The onboarding funnel: steps, dwell, churn, and the split by source.

environment defaults to production so an engineer's phone on the srvc.page tunnel (which reports development) does not read as a stranger who left; all shows both. unit=people folds a device's visits into one walk; our_emails names the staff whose walks are held back until ours=true (include_ours=true is the same switch under the name every other readout uses). Ours by runtime/ours.py — internal devices, personas, rehearsals, bench origins, @stormy.ai, localhost — are held back whatever list the console passes.
