The five Grafana project SVGs are the original artwork linked from
https://grafana.com/oss/ . They are preserved byte for byte and pinned by
content hash. The projects' software licenses do not license their logos.
Grafana Labs' brand terms remain applicable: https://grafana.com/trademark-policy/

Ubuntu's standalone Circle of Friends SVG comes from the official Ubuntu
Community Hub merchandise assets page. The original SVG is preserved byte for
byte, including its colors and geometry. Ubuntu and Canonical are registered
trademarks of Canonical Ltd.; no open-source artwork license is claimed.

The five PNG files are the application icons published by the named developers
on their verified App Store product listings. They are preserved without
recoloring, tracing, cropping or changing their pixels. Apple hosts the artwork;
its availability does not grant an artwork redistribution or trademark license.

DingTalk's packaged SVG adds a rounded-corner display clip around the unchanged
PNG. This is a project presentation adjustment; it is not official vector art.
The original PNG is also included separately.

The source listing, publisher, artwork URL, retrieval date and SHA-256 are
recorded in data/official-icons.json and the distributed catalog.json.
Copyright and trademark rights remain with their respective owners. No
open-source license or individual brand-owner permission is claimed.
