The card shows temporal axes (operational dates), spatial axes (country, location, owner), and numerous measures (compute power, costs, chip quantities, energy efficiency). I should examine the actual column structure and data characteristics to ground my recommendations in what's truly queryable. Let me inspect the main table's columns to see the full range of analytical dimensions.",
