notes: >-
  The readthedocs-hosted docs host is the only reachable LeapYear developer surface;
  its posture is the hosting provider's, not LeapYear's. The corporate domain
  leapyear.io still resolves and is still held on MarkMonitor nameservers after the
  Snowflake acquisition, but it serves nothing and publishes no CAA, SPF or DMARC.
