Clarification on collisions

Hi, I wanted a clarification something regarding Sqids and potential collisions as the README.md feels a bit ambiguous on this point. The sqids-dotnet repo explicitly states that Sqids are "collision-free," but I didn’t see a this claim in sqids-python. There is a mention that IDs are not guaranteed to be "canonical"—is this just an obtuse way of saying collisions are possible? I’d appreciate some clarification on whether Sqids are truly collision-free across implementations. If canonical is being used as a synymon for collisions, I suggest rewording it to "collision" so it's more explicit. Thanks
