Problem

restitution-backend-1 exits with code 1:

Error: Cannot find module 'jsdom'

Root Cause

jsdom is listed in devDependencies (package.json line 54), but the backend uses it at runtime for authoritative server simulation (running Phaser inside JSDOM). The Dockerfile production stage runs npm install --production --omit=dev, which strips devDependencies.

Fix

In package.json, move "jsdom": "^20.0.2" from devDependencies → dependencies.

Dependencies

Blocks: e2e smoke test (smoke test needs a running backend)
Blocked by: None
