+## Local Dev
+
+- `opencode dev web` proxies `https://app.opencode.ai`, so local UI/CSS changes will not show there.
+- For local UI changes, run the backend and app dev servers separately.
+- Backend (from `packages/opencode`): `bun run --conditions=browser ./src/index.ts serve --port 4096`
+- App (from `packages/app`): `bun dev -- --port 4444`
+- Open `http://localhost:4444` to verify UI changes (it targets the backend at `http://localhost:4096`).
