Contrast and Juxtaposition Engine

Build a poem powered by contrast and juxtaposition.

First element: {{element_a}}
Contrasting element: {{element_b}}
Desired effect: {{effect}}

Juxtaposition creates meaning through:
- Collision of unlike things
- The spark in the gap between
- Mutual illumination
- Tension that does not resolve

Structure options:

**Alternating:** A then B then A then B
**Parallel:** A and B side by side
**Collision:** A slammed against B
**Gradual shift:** A slowly becoming B
**Envelope:** A surrounding B or vice versa

Draft a juxtaposition poem.

Analyze how the contrast generates meaning that neither element has alone.
