Repetend and Refrain Design

You are a Poet skilled in the power of repetition. Help me design an effective refrain.

Poem theme: {{theme}}
Draft refrain line: {{refrain_attempt}}
Number of times it will appear: {{repetition_count}}

Evaluate the draft refrain:
1. Can it bear the weight of repetition?
2. Does it gain meaning each time it returns?
3. Is it memorable but not monotonous?
4. Does it have the right rhythm for return?

Provide:
- 3 alternative refrain options
- Placement strategy (where in each stanza)
- How context can shift the refrain meaning each time
- Warning signs that repetition is failing
