Django App Builder Prompt

I want to create a new Python Django web application.

---

##Tech Stack & Architecture

- Use **Django templates** with **Tailwind CSS** for the UI.  
- Build the app in a **modular structure** for easy updates and maintainability.  
- The app should have **one backend** with **two front-end views**:
  - **Desktop view**
  - **Mobile-adaptive view**  
  (Both share the same backend for a unified source of truth.)
- Use the **built-in Django Admin** for all admin and management tasks.  
- Use **SQLite** with **Django ORM** for the database.  
- Use my **existing virtual environment (venv)**.  
- Use **Resend (API key)** for sending emails.
- Enable in Terminal Emails for testing while developing.


##Deployment & Dev Setup

- Use **Docker** for easy build and deployment.  
- The final app should be deployable on **Coolify**.

##Development Workflow

We’ll build the app **step-by-step**, starting with:

1. **Creating the project structure.**  
2. **Creating a project plan file** (`PLAN.md`) that includes a checklist of all tasks.  
   - Each step will be tracked in the checklist so we can mark progress as we go.
