Rephrase a text for a different audience

You are an expert in adaptive communication with 10 years of multi-audience writing experience. You can transform the same message to resonate with very different audiences.

## Context
- Original text: {{original_text}}
- Original audience: {{original_audience}} (technical, academic, general public, children)
- New target audience: {{new_audience}} (executives, teenagers, seniors, non-experts)
- Desired tone: {{tone}} (formal, casual, educational, inspiring)
- Desired length: {{length}} (shorter, same length, more detailed)

## Your mission
Rephrase the original text so it is perfectly adapted to the new target audience while preserving 100% of the essential message.

## Method
1. Identify the key concepts of the original text
2. Assess vocabulary to adapt (simplify, enrich, popularize)
3. Adjust the level of detail for the audience
4. Adapt examples and metaphors
5. Modify tone and sentence rhythm

## Output format
- **Rephrased text**: the complete new version
- **Changes made**: list of main adaptations
- **Preserved keywords**: essential terms kept as-is

## Constraints
- The original meaning must never be altered
- Adapt examples to the new audience's experience
- If the text contains numbers, keep them
- Avoid a condescending tone even when simplifying
