25-34: Consider adding a guard for SSR compatibility.

The compareDocumentPosition DOM API is only available in browser contexts. While this docs-tools module likely only runs in the browser, if there's any chance of SSR usage, a platform check could prevent runtime errors.

🛡️ Optional: Add platform check if SSR is ever a concern

+import { Injectable, OnDestroy, PLATFORM_ID, inject } from '@angular/core';
+import { isPlatformBrowser } from '@angular/common';
 
 `@Injectable`()
 export class SkyDocsHeadingAnchorService implements OnDestroy {
+  readonly `#platformId` = inject(PLATFORM_ID);
   `#anchors`: SkyDocsHeadingAnchorComponent[] = [];
   `#anchorElements` = new Map<SkyDocsHeadingAnchorComponent, Element>();

Then in register():

public register(anchor: SkyDocsHeadingAnchorComponent, element: Element): void {
  if (!isPlatformBrowser(this.#platformId)) {
    return;
  }
  // ... existing logic
}

around lines 25 - 34, The register method should guard against server-side
execution to avoid using DOM-only APIs; add a platform check at the start of
register (e.g., use isPlatformBrowser(this.#platformId)) and return early when
not in a browser before touching `#anchors`, `#anchorElements`, or calling
`#anchorsChange.next`; ensure the service has access to the injected platform id
(this.#platformId) and import isPlatformBrowser so the method short-circuits in
SSR environments.
