I'll build the full MindVault application — a premium dark luxury AI-powered knowledge workspace. Let me start by setting up the project structure and design system.

Now let me set up the task list and start building this comprehensive application.

Let me save the logo and set up the design system first.

Now let me set up the complete design system - globals.css, tailwind config, layout, and all the core components:

Now let me update the layout and build the sidebar navigation component and app shell:

Now let me build the onboarding/landing page and the dashboard:

Now let me build the Dashboard page with all its components:

Now write the dashboard page and move on to the Personal Space:

The full MindVault application is now built with all 8 screens specified in your wireframe document. Here's what was implemented:

• Design System: Dark luxury theme with deep charcoal backgrounds (#0B0F14), luxury gold accent (#D4AF37), AI glow blue (#3B82F6), Inter + Sora typography, and custom animations for voice capture pulse and smooth fade-in transitions.
• Onboarding Flow (4 steps): Welcome screen with logo, sign-in form, usage type selector (Personal/Team/Research), and permission grants — all with calm, premium UX and step indicators.
• Dashboard: Greeting with quick voice capture CTA, activity stat cards, today's tasks, recent memories timeline, upcoming meetings, and an AI insights panel with contextual suggestions.
• Personal Space: Private brain vault with voice/text/screenshot capture options, semantic memory search bar, type filters, and a rich memory timeline with pinning, editing, and room-sharing actions.
• Rooms: Room list with confidential badges, member counts, and active topics. Room detail view with 4 tabs — Timeline (decisions/updates/fixes/notes), Task Intelligence (AI-detected responsibilities), Knowledge Graph (visual node connections), and AI Summary (current project state).
• Meet Mode: Three-state meeting flow — pre-meeting (type selection, room picker), live recording (real-time transcription with speaker labels, detected tasks, highlighted decisions), and post-meeting (auto-generated minutes, action items, follow-ups with export/save).
• Memory Search: Semantic search UI with suggested queries, recent searches, filtered results showing source, relevance scores, timestamps, and related memory connections.
• Notifications & Settings: Stacked notification cards with priority strips and type filtering; settings with profile management, room permissions, data privacy toggles with encryption status, voice recording configuration, and data export capabilities.

Let me first examine the current theme setup and globals.css to understand what needs to change.

Good -- next-themes is already installed. Now let me check for any hardcoded dark-theme colors across all pages and components:

Good -- no hardcoded hex or raw color classes in the pages. The design token approach means I just need to: (1) add a .light theme in globals.css, (2) create a theme provider using next-themes, (3) add a theme toggle button to the top bar, and (4) update the root layout. Let me also check the onboarding page since it's outside the dashboard layout:

Good -- all pages use semantic design tokens (bg-background, text-foreground, etc.) so the theme switch will work globally. Now I'll make 4 changes: (1) add light mode CSS variables, (2) create a theme provider, (3) add a theme toggle to the top bar, and (4) update the root layout.

Now let me also update the scrollbar styles so they adapt to the theme, and fix the shimmer animation:

Now create the theme provider and toggle components:

Good -- the theme provider already exists. Now I need to: (1) update the root layout to use it with attribute="class" and default to dark, (2) add the theme toggle to the top bar.

Now add the theme toggle to the top bar:

Now let me also add a theme toggle to the sidebar so it's accessible from there too, and ensure the onboarding page's logo renders well on light backgrounds by adding a subtle drop shadow:

Now let me make sure the logo on the onboarding page has proper contrast in light mode (the logo has a black background so it needs a rounded container):

I've added full light/dark mode switching to MindVault. The changes include: a complete set of light theme CSS variables (:root) with warm off-whites, proper contrast ratios, and a refined gold primary that works on light backgrounds, while the dark theme is preserved under .dark. The next-themes ThemeProvider wraps the app with attribute="class", defaultTheme="dark", and enableSystem for OS-level preference detection. A sun/moon toggle button appears in both the top bar and sidebar footer, and all dynamic styles (scrollbar, shimmer animation) now use CSS variable references so they adapt automatically.
