Courtside MVP: engine, web app, Docker + Cloudflare Tunnel deploy, docs
Tournament engine (pools, single/double elimination, standings with proper tiebreaks, withdrawals, two-court queue with ETAs and alerts), a single-process Node server with SQLite via node:sqlite and a WebSocket live board, organizer desk, QR landing page that follows the tournament phase, Dockerfile and compose with cloudflared, and documentation for deploying and running a day.
