Design for a standalone Playwright-based soak runner that drives 16
authenticated browser sessions across 4 concurrent rooms to populate
staging scoreboards and hunt stability bugs. Architected as a
pluggable scenario harness so future UX test scenarios (reconnect,
invite flow, admin workflows, mobile) slot in cleanly.
Also gitignores .superpowers/ (brainstorming session artifacts).
