platform-access

Inject the WINDOW token from @rt-tools/core instead of referencing window directly, casting to Window & typeof globalThis for constructors like IntersectionObserver. For services that must run without a DOM, take the window inside a method under a platform check rather than as a class field.

Use inject(PlatformService).isPlatformBrowser instead of isPlatformBrowser(inject(PLATFORM_ID)) or typeof window checks. Presence-of-global checks break in environments where the global is stubbed, such as test runners.

No environment check is needed around storage when using StorageService from @rt-tools/core, because it falls back to in-memory storage outside the browser automatically. Wrapping reads and writes in an isBrowser condition is dead code.

The token factory throws when the document has no defaultView, which happens in environments without a DOM. Services that must work without markup should inject the window inside a method guarded by a platform check, not as a class field.

Files like *.logic.ts and *.util.ts have no DI, so they accept the window as a function parameter. The calling component or service injects WINDOW and passes it in.

Direct access is deliberately kept only in three places: the anti-theme-flicker inline script in index.html, the startup failure handler in main.ts, and code inside page.evaluate in end-to-end specs. New exceptions require explicit owner agreement.
