- Renamed `app/views/cities/_map.html.erb` to
`app/views/shared/_map.html.erb`
- Updated references to the map partial in `cities/show.html.erb` and
`weather_arts/show.html.erb`
- Adjusted the layout in `cities/show.html.erb` and
`weather_arts/show.html.erb` for visual consistency.
This refactoring improves code reusability and maintainability by
centralizing the map component. It also improves the visual
presentation of the application.
