sprint-planning

1. Understand the context

• Read the project README/CLAUDE.md for mission, status, and next steps
• Read the backlog (product/**/backlog.md) and story map (product/**/story-map.md)
• Identify what's already built by exploring the codebase
• Identify the sprint timebox (dates, deadlines, events)

2. Propose a sprint goal

• Write a single sentence that captures the sprint's purpose
• Frame it as a user outcome, not a task list
• Example: "A dancer landing on the festival page can sign up and join a group dinner."
