Portal (after bootstrap):
  https://${domain}/portal

Day 2: portal sessions last 7 days. Re-run the bootstrap command above any
time to print a fresh owner sign-in link, or use
  docker compose run --rm control-plane provider-msp portal-link --email you@example.com
for any invited teammate. Set RESEND_API_KEY in .env to enable emailed
sign-in links instead.

Lease signing public key (your provider MSP license must bind this key;
re-print any time with ./setup.sh --print-lease-signing-public-key):
  $(derive_lease_signing_public_key)
