what is so "architecture" about constants?
There should be some research into how many code bases have been ruined by these panacea peddlers.
I'm all for simplifying the indecipherable, but this is a case where things need to be made as simple as possible, but not simpler. Design systems determine how everything looks and feels, and this means specifying a number of things together, such as what colors a button has, how it looks when pressed and hovered, how dialogs look, what is dark mode or light mode, etc. Calling this "constants" is simplistic and a sign you are commenting on problems you know nothing about.
