Supabase Todo App Spec (Minimal Rules)

Use the project specifications and guidelines to build the Todo app.

Todo is a web app that allows you to manage your todos.

Follow these rules:
- Implement CRUD operations for todos.
- Use authentication where applicable.
- Use the project's existing structure and conventions.
- Keep the UI simple and accessible.
- Ensure error handling and loading states for all async operations.

Note: This ruleset is intentionally minimal; fill in missing specifics by reading the project docs and codebase before implementing features.
