min/max answer "would this be rejected?", which is a different
question from "what would anyone actually pick?", and the gap between
them is usually enormous: a period legal to 5000 is interesting
below about 200, so a slider drawn on the legal range spends 96% of
its travel where nobody goes. Declaring the useful range is what lets
a control be drawn on it and a model be told it.
Purely advisory — nothing rejects a value outside it, since a bound
that rejects is what min/max already are.
The legal range. Outside it is an error.
