## Description
Remove `orange` from the `bb1d` gradient and change the `80%` to `50%`. This will make `--building-color1` solid for the top half, and then transition to `--window-color1` for the bottom half.
## Instructions
## Tests
```yml
tests:
- text: test-text
testString: const bb1d = code.match(/\.bb1d\s*{[\s\S]+?[^}]}/g)[0]; assert(/background\s*:\s*linear-gradient\(\s*var\(\s*--building-color1\s*\)\s*50%\s*,\s*var\(\s*--window-color1\s*\)\s*\)\s*(;|})/g.test(bb1d));
