+# 59. Create Theme System Architecture
+
+meta:
+  id: podcast-tui-app-59
+  feature: podcast-tui-app
+  priority: P1
+  depends_on: [09]
+  tags: [theming, architecture, solidjs, design-system]
+
+objective:
+- Design and implement a flexible theme system architecture
+- Support multiple color themes (Catppuccin, Gruvbox, Tokyo, Nord, custom)
+- Provide theme switching capabilities
+- Ensure theme persistence across sessions
+- Define theme properties (colors, fonts, spacing, borders)
+
+deliverables:
+- `/src/themes/types.ts` - Theme type definitions
+- `/src/themes/theme.ts` - Theme system core implementation
+- `/src/themes/themes/` - Directory with theme files
+- `/src/themes/default.ts` - Default system theme
+- `/src/themes/hooks.ts` - Theme hooks (useTheme, useThemeColor)
+
+steps:
+- Define `Theme` interface with properties: name, colors, fonts, spacing, borders
+- Create theme color palettes (background, foreground, primary, secondary, accent, etc.)
+- Implement `ThemeManager` class to handle theme loading, switching, and persistence
+- Create `useTheme` hook for React/Solid components to access current theme
+- Implement `useThemeColor` hook for accessing specific theme colors
+- Add theme persistence using localStorage or file-based storage
+- Export theme utilities for programmatic theme access
+
+tests:
+- Unit: Test theme loading from JSON file
+- Unit: Test theme switching updates current theme
+- Unit: Test theme persistence saves/loads correctly
+- Integration: Verify components update when theme changes
+
+acceptance_criteria:
+- Theme system can load multiple theme definitions
+- Theme switching works instantly across all components
+- Theme preferences persist across application restarts
+- Theme colors are accessible via hooks
+- Theme manager handles errors gracefully
+
+validation:
+- Run `bun run build` to verify TypeScript compilation
+- Test theme switching manually in application
+- Verify localStorage/file storage works
+- Check all theme colors render correctly
+
+notes:
+- Theme files should be JSON or TypeScript modules
+- Use CSS variables or terminal color codes
+- Consider dark/light mode compatibility
+- Themes should be easily extensible
