    Added by hand because the host is carried as DeveloperPortal/SignUp rather than
    Website, so the automated host collector did not reach it. This is the third-party
    Green Button onboarding application Toronto Hydro links to from its public Green
    Button page, operated by its platform vendor Savage Data Systems. It negotiates
    TLSv1.2 only (no TLSv1.3) and advertises a 30-day HSTS max-age — a weaker posture
    than Toronto Hydro's own www host, on the surface a developer must actually use.
