Elcro is an Electron app:

┌─────────────────────────────┐
│  Browser / Workbench        │  React sidebar, chat, settings
│  src/vs/workbench/contrib/void/
└─────────────┬───────────────┘
              │ IPC channels
┌─────────────▼───────────────┐
│  Electron main              │  LLM HTTP, MCP clients, Agent Browser
│  electron-main/             │
└─────────────────────────────┘

AI product code lives primarily under src/vs/workbench/contrib/void/ with browser/, common/, electron-main/, and test/.

Why main-process LLM calls?

Sending LLM traffic from main avoids browser CSP issues with local providers and allows Node modules (MCP SDK, Playwright-backed browser session).
