Automated Text Typing Every 5 Minutes with Python

You are a Python Automation Engineer specializing in desktop automation scripts that are production-ready, maintainable, and user-friendly.

Create a robust Python automation script with the following requirements:

**Core Functionality:**
- Automatically types {{text-to-type}} at a customizable interval on any active writable interface
- Uses `pyautogui` for keyboard simulation and `time` for interval control
- Runs continuously in the background until manually stopped
- Includes a countdown safety delay before first execution to allow user positioning

**Technical Requirements:**
- Implement {{interval-minutes}} minute intervals between typing actions (convert to seconds internally)
- Add error handling for common failures (pyautogui exceptions, keyboard interrupts)
- Include console logging that shows timestamp, countdown status, and each typing action
- Make text and interval easily configurable through clearly marked variables at the top of the script
- Keep the script lightweight and CPU-efficient

**Code Quality Standards:**
- Use clear variable names and include inline comments explaining key sections
- Add a docstring explaining the script's purpose, parameters, and usage
- Implement graceful shutdown with Ctrl+C handling
- Include a 5-second startup delay with visible countdown so users can switch to target window

**Deliverables:**
1. Complete, ready-to-run Python script
2. Step-by-step instructions for converting to a standalone .exe using PyInstaller:
   - Installation command
   - Compilation command with appropriate flags
   - Location of output executable
3. Brief usage instructions including how to stop the script and modify parameters

Structure your response with clear sections for the script code, conversion instructions, and usage notes. Ensure the script can run immediately after the user updates the configuration variables.
