For the cleanest swirl, keep both doughs the same softness before stacking and roll them to identical dimensions; if one is softer, chill it a few extra minutes. If dried cranberries are very chewy, pulse them briefly in a food processor for finer bits that slice more cleanly. To prevent flat cookies, ensure the dough log is well-chilled and the oven fully preheated. Flavor boosters include swapping vanilla for almond extract or adding a pinch of cardamom to the flour. The dough log freezes well for up to 2 months; thaw in the fridge until sliceable, then bake from cold. If edges crack while rolling, patch with a bit of dough and continue, and always use a sawing motion with a sharp knife for neat rounds.
