Gabriel Franco 970206fb99 feat(backend): scaffold matchmaking server project

Bare HTTP + WebSocket bootstrap (health check route, ws upgrade,
connection logging) with matchmaking/ and rooms/ reserved but
unimplemented. No matchmaking logic yet.

Also adds root README.md (project overview) and AGENTS.md (architecture
map, code style, git workflow).

Raw Blame History

Theme Guess

A browser game about syntax-highlighting themes. A snippet of code is rendered with every token type (keywords, strings, functions, variables, comments, ...) in a neutral color. You click a token, every token of that same kind lights up together, and you pick a color for it — repeat until the whole file is themed. Reveal shows how close your from-scratch palette landed to a real theme (Gruvbox, Tokyo Night, VS Code Dark+, GitHub Dark, Dracula, Catppuccin), token kind by token kind.

The project is moving from a single-player-only page toward supporting multiplayer matchmaking (race another player to the closest match on the same theme/snippet). This repo is split into a frontend game client and a backend matchmaking/realtime server so that work can land independently.

Layout

frontend/   Canvas game client: Vite + TypeScript, no UI framework.
backend/    Matchmaking + realtime session server: Node, HTTP + WebSocket.

Each package has its own package.json, dependencies, and scripts — see frontend/README.md-equivalent notes below and backend/src/*/README.md for what's reserved but not implemented yet.

Running the frontend

cd frontend
npm install
npm run dev       # Vite dev server with HMR
npm run build     # type-check + production bundle to dist/
npm run typecheck # tsc --noEmit only

Running the backend

cd backend
npm install
npm start         # node src/index.js
npm run dev       # same, with --watch

Boots a plain HTTP server (with a /health check) and attaches a WebSocket server to it. Matchmaking and room/session logic are not implemented yet — see backend/src/matchmaking/README.md and backend/src/rooms/README.md.

Status

Single-player game: playable. Multiplayer: backend is a bare HTTP+WS scaffold with no matchmaking logic yet; frontend has no multiplayer UI yet. See AGENTS.md for architecture notes and contribution conventions.
