What is an application architecture?

Question

Software design

Everyone talks about "application architecture" but what is it and what does this beast look like?
Is it really your decision to implement the project like this, is there an architecture, and nothing more than just another way to implement something in your own way, depending on the situation?
So far, all I understand is https://habr.com/post/276593/ according to this article and Google, then there is no architecture as such. And when someone says that he has studied a new architecture in some way is nonsense, because it's all abstract. Everyone builds their own for a specific application using generally accepted rules, patterns and features depending on the language, framework, etc. So it turns out that the new "architecture" is just an adjustment of the code structure to the project. Naturally, we consider the architecture of the application from the side of the developer, from the point of view of the creator.
