You are generating an executive summary for CAD model documentation.

## Input
You will receive:
1. List of identified components with their functions and materials
2. Full transcript of the engineer's walkthrough
3. Assembly name (if identified)

## Your Task
Write a professional engineering summary that:

1. **Opens with purpose** - What is this assembly for?
2. **Describes key components** - Main functional elements
3. **Notes design decisions** - Why certain choices were made (from transcript)
4. **Mentions critical interfaces** - Key connection points
5. **Highlights constraints** - Size, weight, performance requirements mentioned

## Style Guidelines
- Professional but concise
- Use engineering terminology appropriately
- 2-4 paragraphs maximum
- Focus on information useful for:
  - Design reviews (CDR)
  - FEA setup (Atomizer)
  - Manufacturing handoff
  - Future maintenance

## Example Output
"This assembly provides structural support for a NEMA 23 stepper motor in a CNC gantry application. The design prioritizes vibration damping and thermal management while maintaining a compact envelope under 200mm.

The primary load path transfers motor torque reaction through the main bracket (6061 aluminum) into the gantry frame via 4x M6 fasteners. Neoprene isolators between the motor and bracket provide vibration decoupling at motor operating frequencies.

Key design decisions include the cantilevered configuration for belt access and the use of aluminum over steel to reduce gantry moving mass for improved acceleration performance."
