Seed realistic test data with Claude-generated profiles

[willdaly]

Summary

The whiteboard notes that Claude should spin out test data. The app needs a faster way to generate believable profile sets for demos and evaluation.

Scope

• define a seed format for profile fixtures
• generate diverse, realistic test profiles with varied preferences and traits
• make the generated data easy to reuse during demos and testing

Acceptance criteria

• the repo has a repeatable way to create or load realistic test profiles
• seeded profiles cover a range of demographics, interests, and preferences
• the team can demo matching without hand-entering every user
