Story Point Estimation Support

Help me prepare this story for estimation by breaking down its complexity.

USER STORY:
[The story and acceptance criteria]

TECHNICAL CONTEXT:
- Existing codebase: [Relevant details]
- Similar past stories: [Reference if available]
- Team familiarity: [High/Medium/Low with this area]

Analyze complexity across:
1. Business logic complexity (how many rules/conditions?)
2. UI complexity (new screens, complex layouts, animations?)
3. Integration complexity (APIs, services, third-party?)
4. Data complexity (new models, migrations, queries?)
5. Testing complexity (how many scenarios to test?)
6. Accessibility complexity (custom components, new patterns?)
7. Unknown/risk factors (new technology, unclear requirements?)

Provide:
- Suggested relative size (XS / S / M / L / XL)
- Key factors that drive the estimate up or down
- Questions that could change the estimate significantly
