Chart-ready earnings quality data comparing net income against cash generation over time.
Use `series` for absolute values (Net Income, Operating Cash Flow, Free Cash Flow) and
`rates` for quality ratios (FCF/Net Income, OCF/Net Income). Periods are sorted ascending.

A company with FCF consistently exceeding net income has high-quality earnings backed by real cash generation.
