Seed, real,
frozen.
Three copies, easily confused
They open in the same program and can look alike, which is exactly the danger. Before any change, check the title bar in Desktop: it names the project you're in.
Where do you try something?
A number on a card is cut off. You think less spacing above the value might fix it, but you're not sure how much.
Predict first: where do you try it?
The seed and the real project answer different questions. The seed answers how Desktop writes it. The real tile, with its real text and size, answers whether it works. You can look at a change in the real project as often as you like, as long as you close it with Don't save.

The rule, in one breath
The seed teaches the format. The real project proves the effect. The export stays frozen.
Change the seed by hand and save it. Try things in the real project but save only a checked build. Never touch the export; make a new one.
