Actual texts governing source, specification, runtime and typeface.

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.

Browser runtime and font
The device runtime and self-hosted typeface retain their upstream notices. Component licensing is separate from tag validation and from a future certification mark.
