Defaulting to verbose output pollutes the build logs during CI, which can be obscure any errors or status results. However, silencing output on local builds can make it difficult to debug issues. This checks for verbose output and the build script is running on a TTY, so we only get spinner output in those cases (IE, where the spinners actually work and are able to delete the current output line).
