## Grafana Desert Bloom theme

`themes/desert-bloom.yaml` is adapted from Grafana's experimental Desert
Bloom theme definition:

https://github.com/grafana/grafana/blob/main/packages/grafana-data/src/themes/themeDefinitions/desertbloom.json

The upstream file is part of `packages/grafana-data/`, which Grafana
designates as Apache-2.0 licensed:

https://github.com/grafana/grafana/blob/main/LICENSING.md

Stratum translates the upstream palette into Stratum's theme-token schema,
retains its light-only behavior, and adjusts secondary presentation tokens for
diagram readability. The resulting theme file remains licensed under
Apache-2.0. The complete license text is in `LICENSES/Apache-2.0.txt`.
