Quick recommendation: Start with Visual Studio Code — it’s free, powerful, and has the best ecosystem of extensions for both WordPress and Ghost theme work. Install the Handlebars extension for Ghost files and Intelephense (or similar) for WordPress PHP.
Always develop and test themes locally (LocalWP for WordPress, native Ghost install for Ghost) and use version control before pushing changes live.
