/**
 * SSR-safe environment probes. Use to gate browser-only code paths and
 * react to user preferences without scattering `matchMedia` calls around.
 *
 * - `isBrowser` / `isServer` — synchronous platform check.
 * - `userAgent` — `navigator.userAgent` or `null` on the server.
 * - `prefersDark` — signal mirroring `(prefers-color-scheme: dark)`.
 * - `prefersReducedMotion` — signal mirroring `(prefers-reduced-motion: reduce)`.
 *
 * @example
 * ```ts
 * private readonly platform = inject(WrPlatform);
 * if (this.platform.isBrowser) {
 *   localStorage.setItem('theme', 'dark');
 * }
 *
 * protected readonly dark = this.platform.prefersDark;
 * ```
