The hard-coded list of routes in `isContentPage` may become brittle; consider extracting the paths into a constant or config and using `Array.includes` for clarity and easier updates.

[nitpick] The hard-coded list of routes in `isContentPage` may become brittle; consider extracting the paths into a constant or config and using `Array.includes` for clarity and easier updates.
```suggestion
const NON_CONTENT_ROUTES = ['/home', '/guidelines', '/about', '/announcements'];
const isContentPage = computed(() => {
let path = window.location.pathname;
return !NON_CONTENT_ROUTES.includes(path);
});
```
