As a content creator, when I am in "Creator" mode, I want a functional code editor where I can write or paste my quickstart YAML definition.

This involves integrating a code editor library into the "Creator" view. The editor should be configured for the YAML language to provide basic features like syntax highlighting.

Acceptance Criteria:

• When the user switches to "Creator" mode, a code editor component is rendered on the page.

• The editor is configured with YAML syntax highlighting.

• The user can freely type, paste, and edit content within the editor.

• The editor component is responsive and usable on standard screen sizes.
