pnpm monorepo with three workspaces:
- @sbt/shared: zod ScoreboardState + WebSocket protocol (single source of truth)
- @sbt/server: Fastify REST + raw ws WebSocket + Drizzle/Postgres, run via tsx
- @sbt/web: React + Vite + Tailwind installable PWA
Real-time core: the WebSocket server holds authoritative per-board state in
memory, broadcasts to all clients (editors + OBS overlays) instantly, and
debounces Postgres saves (~750ms). One useScoreboardSync hook powers the editor,
the no-login co-edit control page, and the read-only OBS overlay.
Includes email+password auth (JWT cookie), scoreboard CRUD, logo upload,
customizable scorebug (characters/stocks/score/subtitles/callout/side-swap/theme),
Docker Compose + Caddy/nginx deploy configs, and docs/PLAN.md.
