Provider and model are what anyone opening the simulation dialog came for. Shown
flat beside them, the five optional parameters turned the common case into a
seven-field form for a choice most runs do not make.
NodeSettingField gains an optional group, and the dialog renders those fields in
a collapsible section, closed until opened. A closed section that holds values
says how many, so one that is doing something never looks like one that is not -
and it counts a temperature of 0, which is a real setting rather than an empty
field.
The field markup moved into one ng-template used by both the plain list and the
sections. It is about a hundred lines of switch; a second copy would have drifted.
The open-state is a signal rather than a mutated Set. The component is OnPush, so
a Set only re-rendered when the change arrived through a template event - true
here by luck, and false the moment anything toggled a section from code. A test
caught it.
577 frontend tests green; the collapsed-by-default assertions fail when the group
is forced open. Initial bundle now 7.28 kB over budget, up from 4.26.
The node editor is untouched: that one is still to be discussed.
