## Script Writing Best Practices
- Write conversationally — how you'd naturally speak
- Keep sentences short (under 20 words for natural pacing)
- Use punctuation to control pacing (periods = pause, commas = brief pause)
- Include pronunciation guides for technical terms
- Add emphasis with bold or capitalization hints
