Wait, but .txt files are plain text files. They don't contain formatting, images, or complex data. So what could Studio Vika be doing with .txt files that they consider top? Maybe they're involved in generating or providing textual content in .txt format that's high quality. Perhaps they produce data, scripts, documentation, or other textual content in this format. Alternatively, the "txt top" part might be a typo or mistranslation, but I have to work with what's given.
