I have the design inspiration (a clean, dark enterprise SaaS interface with professional analytics) and confirmed the codebase structure. Now let me set up a comprehensive plan for this multi-page admin dashboard.

I'll now start with the first task. Let me set up the theme and layout architecture, including the design tokens, global styles, and sidebar navigation structure.

Now let me update the globals.css with the enterprise SaaS theme inspired by the design brief, then create the necessary layout and components.

Now I'll update the layout.tsx to include the sidebar and top navigation structure:

Now I'll create the sidebar component:

Now I'll create the top bar component:

Now let me create a types file for the campaign data structure and then update the page.tsx to show the dashboard. First, let me create the types:

Now let me create seed data for the dashboard:

Now I'll move to the next task and create the Campaign List page. Let me move the todo forward:

Now I'll create the campaign list page with table, filters, and search:

I notice there's a syntax error. Let me fix it:

Let me read and fix the file:

Now let me create the campaign detail/analytics page:

Now let me create the metric cards component:

Now let me create the performance charts component:

Now let me create the lever performance table component:

Now let me create the budget tracker component:

Now let me move to the next task and create the multi-step campaign creation form:

Now I'll create the multi-step campaign creation form. Let me start with the main create campaign page:

Now let me create the first step component (Basic Info):

Now the objective step:

Now the lever selection step - this is more complex:

Now the preview step:

Now let me create the lever configuration modal:

Now let me create a dashboard landing page:

Now let me create placeholder pages for the other sections and move to the final task:

Now let me update the main page.tsx to redirect to dashboard:

Now let me move to the final task and do some Polish and final touches:

Now let me create some utility/helper components and make sure everything is polished. Let me check if I need a Label component from shadcn:

Great! The Label component exists. Now let me mark all tasks as complete:

Now let me explore the existing codebase structure to understand what's already built:

Let me check the existing campaign pages to understand the current structure:

Now let me create a comprehensive plan for the lifecycle upgrade:
