+ * Static server/client detection for tree-shaking support.
+ *
+ * This file re-exports `isServer` from `@tanstack/router-is-server` which uses
+ * conditional exports to provide different values based on the environment:
+ *
+ * - `browser` condition → `false` (client)
+ * - `node`/`worker`/`deno`/`bun` → `true` (server)
+ * - `development` condition → `undefined` (for tests, falls back to router.isServer)
+ *
+ * The bundler resolves the correct file at build time based on export conditions,
+ * and since the value is a literal constant, dead code can be eliminated.
+ *
+ * @example
+ * ```typescript
+ * import { isServer } from '@tanstack/router-core'
+ *
+ * // The ?? operator provides fallback for development/test mode
+ * if (isServer ?? router.isServer) {
+ *   // Server-only code - eliminated in client bundles
+ * }
