## Measured notes (no inference beyond what was returned)
- Rank 9, "Figure Heloc" (FIGR_HELOC), carries no 24h price change in the
  response (field null); its 24h % cell is rendered "n/a" and its last_updated
  timestamps (2026-10-25T13:14:38Z) differ from the others (2026-10-26T11:13:56Z).
- All other rows report a numeric 24h % change; negative/positive signs are
  preserved as returned.
- CSV is authoritative for machine parsing; markdown is for human reading.
