  Announced expansion of Microsoft's existing Cheyenne footprint: acquiring
  3,200 acres southeast of downtown to roughly triple its presence. Distinct
  physical site from the Meta Cheyenne data center (separate record). Single
  primary (operator) source, so aggregate confidence medium despite
  high-confidence signals.
