Build me a browser based DOOM style FPS in TypeScript that feels like the original game, but runs without any engine. I want a hand made raycasting renderer with textured walls, sprites, HUD, and an automap, plus simple shooting and door interaction.

It should have the full single player campaign with all 6 Knee Deep in the Dead levels, and also online multiplayer with both co op and deathmatch. For multiplayer, I want a lobby where players can see open rooms and join without typing room codes, plus smooth play that hides lag as much as possible.

Use the browser as the target, with a clean local dev setup, and make sure it can run single player by itself and multiplayer with a separate server. If you need current docs or examples for the networking part, look them up online. Keep it playable, polished, and close in feel to classic DOOM.
