+- The application now uses `provideZonelessChangeDetection()` instead of `provideZoneChangeDetection()`.
+- Removed `zone.js` from the application dependencies and from the build/test polyfills, including the `zone.js/testing` test bootstrap import.
+- Replaced the remaining Zone-dependent `fakeAsync` / `tick` test setup with native `async` / `await fixture.whenStable()`.
+- Migrated the remaining loading and rendered-content state in `ActivityDescriptionPageComponent`, `ReportComponent`, `UsageComponent`, and `MarkdownViewerComponent` to signals so their templates update correctly without Zone.js.
+- <b> DSOMM is now completely zoneless at runtime and in its test configuration 🎉. </b>
+- **Files:** `angular.json`, `package.json`, `package-lock.json`, `src/main.ts`, `src/test.ts`, `src/app/pages/settings/settings.component.spec.ts`, `src/app/component/markdown-viewer/*`, `src/app/pages/activity-description/*`, `src/app/pages/report/*`, `src/app/pages/usage/*`

 | 4 | Test Runner | • **Deprecated subdependencies:** Karma pulls in `glob@7.2.3`, `inflight@1.0.6`, and `rimraf@3.0.2` — all deprecated, cluttering `pnpm install` with warnings. <br>• **pnpm incompatibility:** Karma's Webpack-based builder (`@angular-devkit/build-angular:karma`) cannot resolve transitive dependencies (e.g. `@babel/runtime`) under pnpm's strict symlinked `node_modules`. Currently requires `node-linker=hoisted` in `.npmrc` as a workaround, defeating pnpm's strictness benefits. <br>• **Modern tooling alignment:** Build/serve already use esbuild/Vite via `@angular/build`. Tests are the last piece still on the legacy Webpack pipeline. Migrating would allow dropping `@angular-devkit/build-angular` entirely. | High | Karma is deprecated. Migrate to a Vite-based test runner (e.g. Vitest or `@angular/build` native test support). |
