"Dummy" is one of those words that works multiple shifts. Sometimes it is a stand-in, like a dummy variable in maths. Sometimes it is a model, like a crash test dummy. Sometimes it is a prototype: a dummy page that proves the layout is ready. And yes, sometimes it is an insult. We are not using that meaning today. Dummy Corp is a demo company, not a judgement. So when you see "dummy" here, read it as temporary, not trivial. Placeholder, not pointless.
