Context

Roadmap reference: P2 - No dark mode

Tailwind CSS is configured in the project but the dark: variant is not applied to any components. Users who prefer dark mode get no themed experience.

What to do

  1. Enable darkMode: 'class' (or 'media') in tailwind.config.js
  2. Add a dark mode toggle button (sun/moon icon) to the main navigation or settings area
  3. Persist the user's preference in localStorage
  4. Apply dark: Tailwind classes to all major layout and UI components (backgrounds, text, borders, cards)

Acceptance criteria

  • A toggle button switches between light and dark mode
  • Dark mode preference persists across page refreshes (localStorage)
  • All major pages (Dashboard, Batch, Analytics) are readable in dark mode
  • No color contrast accessibility violations introduced in dark mode

Triage assessment: The dark mode infrastructure is partially in place -- darkMode: "class" is set in tailwind.config.js, a ThemeContext with localStorage persistence exists in frontend/src/context/ThemeContext.tsx, and a toggle button (sun/moon icon) is wired up in frontend/src/components/Layout.tsx. However, the dark: Tailwind variant classes are not applied to the actual page components. Batch, Analytics, Analysis, Login, and Register pages all have zero dark: class usages. This needs a developer to systematically apply dark variant classes across all major UI components.

Assigning to @developer for implementation.

Already Resolved

This issue is already implemented on main:

  • frontend/src/context/ThemeContext.tsx provides ThemeProvider and useTheme hook with localStorage persistence and system preference detection
  • frontend/src/App.tsx wraps the app in ThemeProvider
  • frontend/tailwind.config.js has dark mode colors configured
  • Pages and components use dark: Tailwind variants (Login, Register, Layout, ProtectedRoute)

Closing as complete.
