Prompt

# after running `copilot --plugin-dir .GitHub/plugins/cms-development` and installing
Create a light-weight Content Management System that can be used to test
Wordpress themes being developed. The final tool should be able to deploy in
GitHub Pages via an action, so - we also need to create a workflow that will
deploy the site to a GitHub Pages environment. Lastly we need a basic theme to
work on for this application.

Results

• Added a lightweight static CMS under site/ with browser-side editing for site settings, pages, posts, and theme tokens.
• Added a starter theme under site/themes/starter/ so layout and styling changes stay separate from CMS runtime code.
• Added deploy-pages.yml to publish the site/ directory to GitHub Pages.
• Content is intentionally stored in browser localStorage with JSON import/export because GitHub Pages cannot run a writable WordPress backend.
