Licenses and notices

Code and specification

Apache-2.0 governs project code, including commercial use subject to its conditions. CC BY 4.0 governs the specification and requires appropriate attribution when sharing/adapting it. The licenses have their own warranty and rights limitations; a public repository is not a blanket license to every third-party asset or trademark.
