Phase 8: Ship It

Deploy the application at a real address. Migrations as part of the deploy, static files served, environment variables on the host, and a clean commit history with at least one pull request. Write the README properly, including the decision paragraph and the one you would do differently. Then run the deployed checklist as a stranger: deep link refresh, phone on mobile data, console clean, network off mid-request, and a brand new account through first-run. Fix what that finds.
