# Application definition

# admin_interface (and its colorfield dependency) must precede the admin app to
# override its templates. PaletteAdminConfig subclasses AdminConfig, so it *is*
# django.contrib.admin with a custom site that powers the Ctrl/Cmd+K palette;
# PaletteConfig must precede it so palette's admin/base.html override wins.
