c54b6bc165 Tie invalidity indicator to regulator input
Invalid attempts to specify a regulator's set point are now local to
each view of the regulator, and don't affect the regulator model. In
particular, a regulator will be valid and in force even when one of its
regulator input views is showing an invalid specification attempt. The
invalidity indicator should therefore be tied to the input showing
the invalid specification, not to the whole regulator outline item.

f2e84fb64a Enforce the validity of set point specifications
Make a regulator's set point specification private, and split the set
point into a private writable signal and a public read-only signal. The
set point can now be initialized only through the factory method
`insert_new_regulator` and changed only through the setter method
`try_specify_set_point`, which both ensure that the set point
specification is valid and consistent with the set point.

bbd0835a8f Move set point spec validation into Regulator 2025-02-18 12:42:49 -08:00

302d93638d Require regulators to have valid specifications
When an invalid specification is entered into a regulator input, keep it
confined to that input. Reset a regulator input by pressing *escape*.

fef4127f69 Only sync regulator inputs on change
This lets us infer a regulator's role from whether it has a set point
and what text specifies the set point.

de7122d871 Label observable type
Right now, there's only one type of observable, so the label can be
hard-coded.

dc8330df6a Revise observable styling
Distinguish constraints from observables using dark background rather
than marker. Customize focus highlighting. Drop the input type selector
that used to make styling apply to the Lorentz product field but not the
constraint activation check box.
