Detailed Description

Property-layer errors.

Three, and the distinction between them is what makes the fallback chain in
:mod:`feedtwin.props.fluid` possible rather than a pile of ``except Exception``.

``OutOfRange`` in particular is the load-bearing one: a fast tabulated backend
refusing a state point is *routine* -- it means "ask a slower backend" -- while
any other failure is a real error that must not be swallowed.
