/**
 * Isolated Vitest config for the remote patterns.json smoke test.
 * Deliberately separate from the main vite.config.ts so `npm test` stays
 * offline; this suite hits the network.
 *
 * **URLs** — Single source of truth: `extension/common/constants.ts`
 * (`REMOTE_PATTERNS_URL`, `REMOTE_PATTERNS_STAGING_URL`). This config picks
 * one via `--mode` (see npm scripts). If `process.env.REMOTE_PATTERNS_URL` is
 * already set (e.g. fork / custom raw file), that wins and mode is ignored.
 *
 * - `npm run test:remote-patterns` — production (`main`) patterns.json (default Vitest mode)
 * - `npm run test:remote-patterns:production` — same URL, explicit `--mode production` (alias for clarity)
 * - `npm run test:remote-patterns:staging` — `staging` branch patterns.json, `--mode staging`
 * - `npm run test:remote-patterns:production:parity` — production URL + Act 4 (bundled `DEFAULT_PATTERNS` parity)
 *
 * Act 4: **on** for staging by default; **off** for production unless `production:parity` or
 * `REMOTE_PATTERNS_COMPARE_DEFAULTS=true`. See `utils/remote-patterns-smoke-utils.ts`.
