Feature summary
Add breadcrumb navigation across Paulina pages to provide users with clear, contextual navigation paths. Each page (home, search results, authors, works, etc.) should display a breadcrumb trail that reflects the current hierarchy and allows users to easily navigate backward.

Use case(s)
Currently, users exploring content in Paulina (e.g., viewing an author or a specific work) have no clear indication of where they are within the app’s structure. They rely on the browser’s “Back” button or the top navigation bar, which doesn’t reflect their current path.
This can be confusing, especially when users navigate from search results to an author, then to a work — making it hard to retrace their steps or jump back contextually.

Benefits
Improves overall navigation clarity and orientation.

Enhances accessibility by providing a visible and screen-reader-friendly context path.

Reduces user reliance on browser navigation.

Creates a consistent navigation pattern across all Paulina pages.

Helps users understand the structure of the app as they explore deeper levels.
