This host exists to satisfy Tesla's Fleet API partner registration, which will not grant a
developer any vehicle access until it can fetch a public key from a fixed path on a domain
with a CA-issued certificate. It serves exactly two things: that key, at
/.well-known/appspecific/com.tesla.3p.public-key.pem, and an OAuth redirect
page at /callback.
Behind it is a private service that charges two electric cars from rooftop solar surplus. There is nothing else here and nothing to log in to.
