The fonts, images and libraries this site uses, and the license each one comes under.
Both families are bundled with the theme and served from this site. Both are under the SIL Open Font License 1.1, which allows using and redistributing them as long as the license travels with the files.
The photos, the two videos and the footer’s animated “hi!” are placeholders that came with the original design. The design credits its images to the sources below; it names no source for the videos, and the animation’s file names no author, source or license, so neither license is confirmed. Replace them with your own, or with files you have licensed yourself, before you launch.
The code the theme is built with and ships to the browser. Each is under its own license.
