# 1. all_demos includes all demos and is for testing PRs
# 2. reset_components includes media files that are only present in all_demos (only for PRs)
# 3. custom_path doesn't have .launch since the point is to show how to launch with uvicorn
# 4. The same reason as 2 for kitchen_sink_random and blocks_kitchen_sink
