## Build Steps
1. Check the list of sources in the config files is in sync with the current sources
```shell
# running from the noto-emoji repository root directory
python colrv1_generate_configs.py
git diff colrv1/*.toml
```
If configs are in sync, the `colrv1/*.toml` files should contain no diffs.
