Dockerfile

# File: Dockerfile
# Purpose: Build and run the full-stack app (Express API + Vite React client) on Railway using a multi-stage Docker build.
# How it works: Stage 1 installs deps and runs `npm run build` to produce the client at `dist/public`.
#               Stage 2 copies built assets and TS server sources, then starts with `tsx server/index.ts` (no esbuild bundling).
# How the project uses it: Railway detects this Dockerfile (via railway.json builder) and deploys a single container serving API and static UI.
# Author: Cascade (Windsurf)
