pagliagen/cthulhucardgame — reverse-engineered prompt

Build me a Lovecraft themed online trading card game that people can play in the browser. I want users to register, log in, browse the full card collection in Italian and English, build decks, choose one of the five factions, and play real time matches against another player.

The game should feel dark and cosmic horror, with a polished card table, creepy artwork, clear card details, and easy controls. Use the rules from the project, including Vita and Sanità, the seven turn phases, creatures, spells, artifacts, tomes, rituals, horror effects, and the sanity penalties when a player starts losing their mind. A player should lose if their life, sanity, or deck reaches zero, or if the other player completes a ritual.

For beta mode, give everyone all 92 cards and the five starter decks without any shop or packs. Please wire up the backend, database, live matchmaking, WebSocket game state, and frontend screens so I can run it locally and test a full match.
