Let me re-read the plan and key files I need to modify:

Now let me read the dashboard page and mock data to understand the patterns:

I have full context now. Let me set up the task tracking and start building. I'll create the auth context, demo accounts, login page, profile page, sidebar filtering, and dashboard adaptation.

Starting with the auth context and demo accounts. First, let me add demo accounts to mock data and create the auth context:

Now create the auth context:

Now wrap the root layout with the AuthProvider:

Auth context and demo accounts are done. Now moving to the login page:

Now move to updating the shell -- sidebar, dashboard layout, and dashboard page:

First, update the sidebar to filter nav items by role and show dynamic user info with logout:

Now update the dashboard layout with an auth guard:

Now update the dashboard page for role-based views:

Now the final task -- the Profile page:

The login and role-based access system is fully implemented. The /login page features a clean card-based sign-in form with three quick-select demo accounts below it: Super Admin (Carlos Mendez -- full platform access), Tenant Admin (Sarah Chen -- manages Acme Corp users, sees scoped dashboard/audit logs), and Normal User (Elena Rodriguez -- personal dashboard and profile only). The sidebar dynamically filters navigation items per role, the dashboard adapts its content for each role (full stats vs. tenant-scoped vs. personal welcome), and a new Profile page lets any user view their account details and edit their name/email. Unauthenticated users are automatically redirected to /login, and sessions persist via localStorage with a sign-out button in the sidebar footer.

Let me read through all the pages and components to document everything comprehensively:

Now let me read every custom file to capture all features:

Now let me read all the dashboard pages:

I now have complete context on every file. Let me write the feature list:

Now I have every single file and feature read. Let me write the comprehensive feature list:

The FEATURES.md file has been created at the project root with a comprehensive breakdown of all 16 sections covering the tech stack, authentication system (3 demo accounts with role-based access), dashboard shell (sidebar with role filtering), all 10 dashboard pages with their specific features (tables, filters, dialogs, forms), 5 shared components, complete mock data inventory (10 entity types with field definitions), the full file structure, and the design token reference. This document should serve as a complete blueprint to recreate the app from scratch.
