MVP: team habit tracker with Slack check-ins

Patter is a habit tracker for remote teams — think standup bots meet streaks. MVP scope: Slack slash-command check-in ('/patter done shipped the invoice flow'), a web dashboard with team streaks and a weekly summary, and gentle nudges. Auth via Slack OAuth only for now. I have Figma wireframes and a landing page with 300 waitlist emails. Looking for someone who can own the whole build; I'll be a very available product owner.
