float	quality \| None

Detailed Description

An immutable snapshot of one fluid at one state point. All SI.

``quality`` is ``None`` outside the two-phase dome rather than a sentinel.
Backends signal "not applicable" with out-of-band numbers -- CoolProp uses
-1 in one situation and -1000 in another -- and letting either escape into
a mass balance as a vapour fraction is the kind of bug that produces a
plausible-looking wrong answer rather than a crash.
