Type a search term or URL, and it opens the\nproxied site inside a fresh `about:blank` tab.\n\n## Features\n\n- **about:blank cloaking** — proxied sites open in a blank tab so the real\n destination is hidden from the address bar.\n- **In-tab navigation bar** — back / forward / reload / home, a URL bar to keep\n browsing without returning to the homepage, and `Esc` to toggle full-screen.\n- **Tab disguises** — make the tab look like Google Docs, Classroom, Drive,\n Gmail, or Canvas (custom title + favicon).\n- **Panic key** — press a chosen key anytime to instantly jump to a safe URL.\n- **Search engines** — DuckDuckGo, Bing, or Google.\n- **Settings persistence** — preferences saved in `localStorage`.\n\n## How it works\n\n```mermaid\nflowchart LR\n A[Homepage] -->|submit| B{Cloak on?}\n B -->|yes| C[Open about:blank tab]\n C --> D[Disguised shell + iframe → /view]\n B -->|no| E[Navigate to /go]\n D --> F[\"/view (toolbar + iframe)\"]\n F --> G[\"/go?q=…&e=engine\"]\n E --> G\n G -->|normalize input| H[\"/p/<encoded url>\"]\n H --> I[Server fetches target]\n I --> J[Rewrite HTML/CSS links back through proxy]\n J --> K[Serve to browser]\n```\n\n## Files\n\n| File | Purpose |\n| --- | --- |\n| `main.ts` | HTTP entrypoint |\n| `server/app.ts` | Hono routes: `/`, `/view`, `/go`, `/p/*`, static, `/source` |\n| `server/proxy.ts` | Fetch + HTML/CSS rewriting, search-engine normalization |\n| `frontend/index.html` | Homepage with search + settings |\n| `frontend/main.js` | Cloaking, disguise, engine, panic key, settings |\n| `frontend/disguises.js` | Tab disguise presets (title + inline-SVG favicon) |\n| `frontend/viewer.html` | In-tab browser shell (toolbar + iframe) |\n| `frontend/viewer.js` | Toolbar logic: URL bar, nav buttons, bar toggle |\n\n## ⚠️ Limitations\n\nThis is a **server-side HTML-rewriting proxy**, not a full engine like\nUltraviolet/Rammerhead. It works well for simple/static sites and reading. It will\nstruggle with heavy JS apps, logins, video streaming, and strict anti-bot sites,\nwhich is expected given Val Town's serverless execution limits.\n",[],[195],"3c9214bb-65c0-403d-9a33-363e100fb581","proxy.ts","01a064cc-3302-7618-ad73-921bedf9ee1e","01a064cc-3302-7618-ad73-972f0d6ae376",["D",1788397499079],"script","// Core proxy logic: fetch a target URL and rewrite its HTML/CSS so that\n// links, assets, and forms route back through this proxy.\n\nconst PROXY_PREFIX = \"/p/\";\n\nconst SEARCH_ENGINES: Record string> = {\n duckduckgo: (q) => `https://duckduckgo.com/html/?q=${encodeURIComponent(q)}`,\n bing: (q) => `https://www.bing.com/search?q=${encodeURIComponent(q)}`,\n google: (q) => `https://www.google.com/search?q=${encodeURIComponent(q)}`,\n};\n\n/** Turn user input into a real URL.
