/**
|
||||
* Zork LLM Server
|
||||
*
|
||||
* Starts an Express + Socket.IO server that runs Zork I through the
|
||||
* ZorkLlmEngine and serves the same shared client UI as the YAML engine.
|
||||
*
|
||||
* Usage:
|
||||
* npm run dev:zork (development, with file watching)
|
||||
* npm run start:zork (production, from compiled dist/)
|
||||
*
|
||||
* Environment variables:
|
||||
* PORT – HTTP port (default: 3002)
|
||||
* ZORK_STORY_FILE – path to the story file (default: ./data/z-code/zork1.bin)
|
||||
* OPENROUTER_API_KEY, OPENROUTER_MODEL – required
