// Small set of utility functions to transform brand URLs. This is a fairly
// hacky approach used by the HA frontend to transform logos (which may be wide
// and not fit well in thumbnails, or may not respect the users themes) into
// icons. In order to ensure consistency of iconography across the card and Home
// Assistant, this is mirrored here.
