Replace external <link> to fonts.googleapis.com with next/font/google for Cormorant Garamond and Inter. Fonts are now built-time downloaded and served from /_next/static/media, exposed via --font-serif and --font-sans CSS variables that Tailwind's fontFamily reads. Eliminates runtime dependency on Google Fonts CDN (helpful for offline or region-restricted deploys), avoids FOUT through next/font's size-adjusted fallback, and removes two render-blocking external stylesheet requests on first load.

云梦
An AI-driven visual novel where every frame — scenes, dialogue, choices — is rendered by an AI, one frame at a time. You click. It paints. The story unfolds.
How it works
Each turn is three model calls:
[user clicks somewhere on the image]
│
▼
1. Vision model interprets the click against the visible UI
│
▼
2. Text LLM writes the next frame (narration, dialogue, choices)
│
▼
3. Image model renders the entire next UI screen — scene, dialogue,
buttons, all of it — as one painted frame
│
▼
[new image is shown; repeat]
There is no traditional UI. There is only the image. The AI chooses the layout, the colors, the typography, the buttons. Pick "stick figure on grid paper" as your style and you'll get hand-drawn UI. Pick "cyberpunk noir" and you'll get neon HUDs. Whatever fits the world.
One-click deploy
After deploy, set the nine environment variables (see below) in your Vercel project. That's it.
Environment variables
Three providers, all independently configurable. Any OpenAI-compatible chat / image endpoint works (OpenAI, Anthropic via OpenAI-compat proxy, Gemini, OpenRouter, DeepSeek, local Ollama, …).
| Provider | Variables | Recommended |
|---|---|---|
| Text · story director | TEXT_BASE_URL TEXT_API_KEY TEXT_MODEL |
claude-opus-4-7 via Anthropic |
| Image · UI renderer | IMAGE_BASE_URL IMAGE_API_KEY IMAGE_MODEL |
gpt-image-2 via OpenAI |
| Vision · click reader | VISION_BASE_URL VISION_API_KEY VISION_MODEL |
gemini-3-flash via Google |
See apps/web/.env.example for the exact shape.
Local development
Requires Node 20+ and pnpm 9+.
pnpm install
cp apps/web/.env.example apps/web/.env.local
# fill in the nine env vars
pnpm dev
# open http://localhost:3000

packages/engine is the open core — pure TS, no Next.js or browser dependency. Import it directly to build your own visual-novel front-end (Tauri, Electron, CLI, anywhere).
Cost & limits
Each turn costs roughly $0.15–0.25 in API fees with the recommended model trio. A 30-turn session is ~$5–8. There is no rate limiting or auth out of the box — if you make your deployment public, your bill will reflect that. Add limits before sharing widely.
