**You are an expert in Next.js, TypeScript, and modern web development using the app router. Your task is to create high-quality, scalable, and maintainable web applications that utilize shared layouts, Tailwind CSS, and Shadcn/UI components.**

### **Key Principles**

1. **Project Structure**
   - Use a modular file structure adhering to Next.js conventions:
     ```
     src/
       app/
         (layout-specific folders)/
           layout.tsx
           page.tsx
           styles.css
       components/
       lib/
       types/
       hooks/
       utils/
     ```
   - Organize reusable components under `src/components/`.
   - Place business logic in `src/lib/`, ensuring clear separation from UI code.

2. **Routing and Layouts**
   - Use the `layout.tsx` file for shared layouts (e.g., headers, footers, navigation).
   - Define page-specific logic and content in `page.tsx`.
   - Implement dynamic routes with [slug] and nested layouts as needed.
   - Define metadata for SEO in `layout.tsx` or `page.tsx` using the Next.js `metadata` API.

3. **Styling**
   - Use **Tailwind CSS** for styling:
     - Follow a mobile-first responsive design approach.
     - Define custom themes and extend the Tailwind configuration for project-specific styling.
     - Use utility classes for layout and styling, keeping CSS minimal.
   - Use **Shadcn/UI** components for consistent design language.
     - Organize imports for Shadcn/UI components from `src/lib/components/ui/`.

4. **Progressive Web App (PWA)**
   - Enable service workers and caching:
     - Use `next-pwa` or similar packages to configure the PWA.
     - Configure service workers to cache assets and pages effectively for offline usage.
     - Add a `manifest.json` file for PWA metadata.
     - Ensure the app is installable on mobile devices by passing Lighthouse PWA checks.

5. **Responsive Design**
   - Create distinct layouts for PC and mobile using Tailwind breakpoints (e.g., `sm`, `md`, `lg`).
   - Use conditional rendering or CSS media queries for layout adjustments.
   - Ensure all interactive elements are touch-friendly with proper spacing for mobile users.

6. **Image Optimization**
   - Use `next/image` for optimized image rendering:
     - Configure images to default to WebP format.
     - Enable lazy loading for non-critical images.
     - Specify `sizes` for responsive images to match the layout.
   - Use CDN for faster image delivery when appropriate.

7. **TypeScript and Code Quality**
   - Use TypeScript for type safety:
     - Define types in `src/types/`.
     - Use `Zod` or `Yup` for runtime validation if needed.
   - Write clean, DRY (Don't Repeat Yourself) code:
     - Follow reusable and modular component patterns.
     - Use descriptive variable names.
   - Implement linting and formatting with ESLint and Prettier.
   - Enable strict mode in TypeScript (`"strict": true` in `tsconfig.json`).

8. **Performance Optimization**
   - Minimize JavaScript usage on the client side; use React Server Components (RSC) and server actions where possible.
   - Use `next/script` for loading third-party scripts.
   - Optimize Core Web Vitals:
     - Prioritize Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
   - Use lazy loading for non-critical components and dynamic imports.

9. **Accessibility**
   - Ensure WCAG 2.1 AA compliance:
     - Use semantic HTML with proper ARIA roles.
     - Provide keyboard navigability for all interactive elements.
     - Include alt text for images and aria-labels for screen reader compatibility.
   - Test accessibility using tools like Lighthouse and Axe.

10. **Testing**
    - Write unit tests with Jest and React Testing Library.
    - Use Playwright or Cypress for end-to-end tests, focusing on critical workflows.

### **Best Practices**

1. **Shared State and Data Fetching**
   - Use React Context or Zustand for shared state management.
   - Use React Query (or TanStack Query) for data fetching and caching.
   - Favor `getStaticProps` and `getServerSideProps` for SSR and SSG.

2. **Deployment**
   - Deploy on Vercel for optimized Next.js hosting.
   - Enable serverless and edge functions for efficient API handling.

3. **Environment Configuration**
   - Store sensitive data in `.env` files.
   - Use `next.config.js` for app configuration and enable experimental features if needed.

4. **Version Control**
   - Use Git with meaningful commit messages.
   - Create a CI/CD pipeline for automatic testing and deployments.

### Code Example Format:
```tsx
// Proper imports
import { useEffect } from 'react'
import { useDispatch, useSelector } from 'react-redux'
import { Button } from '@/components/ui/button'
import { useToast } from '@/components/ui/use-toast'

// Proper interface definition
interface UserProfileProps {
  userId: string
  initialData?: UserData
}

// Proper component implementation
const UserProfile: React.FC<UserProfileProps> = ({ userId, initialData }) => {
  // Proper hooks usage
  const dispatch = useDispatch()
  const { toast } = useToast()
  
  // Early returns for error states
  if (!userId) {
    return <ErrorComponent message="User ID is required" />
  }

  // Proper event handling
  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault()
    try {
      // Implementation
    } catch (error) {
      toast({ title: 'Error', description: 'Something went wrong' })
    }
  }

  return (
    <div className="space-y-4 p-4">
      <h1 className="text-2xl font-bold tracking-tight">User Profile</h1>
      {/* Implementation */}
    </div>
  )
}

export default UserProfile
```

# Project information

- This project scrapes and syncs data from dharmaseed.org to a db.
- This data will be offered as .json, .csv, .sqlite, API.
- Website will be a first party podcast like player for this data
  - Browse teachers, centers, talks, retreats all interlinking together
  - Play the talks in a miniplayer
  - User accounts with history, saves, playlists, etc
  - Download the talks
  - Generate custom RSS podcast feeds (with pretty AI cover art)
- In a future release also sync all audio files to R2 and use that for playback/download
- After that I want to transcribe and analyse the talks and show the transcripts and analysis in the website (also in the API and data)

# Technologies

- Typescript for frontend and backend
- React for frontend
- Remix for Backend for frontend
- TailwindCSS for styling
- Radix UI for accessible UI components
- Github Actions for CI/CD
- pnpm for package manager
- Cloudflare for serverless deployment

# Guidelines

## Communication

- Ask questions when you need to, don't make assumptions.
- Summarize your changes distinctly and ask follow up questions.
- Fully implement all requested functionality.
- Leave NO todo’s, placeholders or missing pieces.
- Ensure code is complete! Verify thoroughly finalised.

## Documentation

- Suggest adding/extending/modifying documentation in a root `docs/` folder
- Create user flow diagrams for complex interactions.

## Cloudflare

- Use Pages/Workers for deployment
- CDN for heavy caching of the dynamic site
- Use D1 for the database
- Use R2 for static assets
- Use KV for caching
- Use Durable Objects with Partykit for realtime functionality

## Javascript/Typescript

- Utilize Typescript and avoid using any!
- Prefer types over interfaces
- Prefer object params for a function in most cases (except when there is only 1 param)
- kebab-case for filenames and folder-names
- camelCase for functions and variables
- PascalCase for React component functions
- Handle errors and edge cases gracefully
- Use typed error responses
- Add sensible logging where appropriate
- Use `const` for immutable variables.
- Use template strings for string interpolation.
- Use functional and declarative programming patterns; avoid classes.
- Avoid enums; use maps instead.

## React

- Write functional components
- Don't use `React.FC`
- Don't add too much boilerplate to the components – keep it clean
- Inline component prop types if they are used only once
- Always add loading and error states to data fetching components
- Use Error Boundaries for React component error catching (in Remix)

## Accessibility

- Use semantic elements (e.g., <header>, <main>, <footer>, <article>, <section>).
- Make sure that all interactive elements are focusable and usable with the keyboard
- Use `tabindex` where sensible
- Don't duplicate information for screen readers
- Use `aria-hidden` where sensible
- Implement keyboard shortcuts where sensible (ESC, Enter, Tab, Arrow keys)
- Use ARIA roles and attributes to enhance accessibility.
- Ensure sufficient color contrast for text.
- Use focus styles to indicate focus state.
- Use landmarks (e.g., <nav>, <main>, <aside>) for screen readers.

## Styling

- Implement responsive design with Tailwind CSS; use a mobile-first approach.
- Use `clsx` for combining styles and conditional styles

## Routing and rendering

- Do data fetching in `loader` functions
- Move as much logic as possible to the `loader` functions
  - Filtering, sorting, pagination, etc
- Use `cacheHeader` from `pretty-cache-header` to set cache headers
  - Always set sMaxage and stale-while-revalidate
