Same as plain old int - where does int allocate its memory? It does not
allocate. It just resides wherever you define it to be.

The memory for elements of static_vector is inside the static_vector object
itself. When you put your object on the stack, the memory is on the stack.

When an object doesn't fit on the stack (no matter if it's a static_vector
instance or a plain old int), you typically get a stack overflow error and
your program crashes.
