/**
 * A company's at-the-market (ATM) equity offering programs: original agreement date and stated precision, latest amendment, money and/or share capacity, cumulative sold and remaining figures with their own as-of dates, expiry, derived utilization/expiry flags, and source filings. Bare table figures are normalized only from an exact grounded filing scale header. Figures come from verified extractions of the company's own 10-K/10-Q/8-K filings scanned over roughly the last 13 months (ATM programs have no tagged XBRL equivalent) — an empty list means no program was captured there, NOT proof the company runs no ATM program.
