The badge designs themselves are modeled after the badges generated by Shields.io. However, when the Tangram team was putting together our CI pipeline, we realized that we couldn't use a Shields-like service because most of our repositories are private (no public pings, you know).

So, since we're a Rust-heavy organization, we decided to generate our own badges during CI. Seeing that current Rust-based offerings were lacking compared to something like Shields.io... we just made our own!
