As a website visitor, I want to rate pages anonymously with a unique identifier (ID) tied to my device and browser, so my ratings are stored per page without using cookies.

Description

Enable anonymous visitors to rate pages, 1-5 stars. Generate a unique user identifier based on device and browser characteristics (no cookies). Store ratings per page, linked to the identifier, in a collection.

Acceptance Criteria

Rating Submission:

Users can rate a page (1-5 stars) via a star widget.

Rating submission requires no login or personal data.

Unique Identifier:

Generate a unique ID using device and browser fingerprint.

ID remains consistent for the same device/browser combination.

No cookies or local storage used for ID generation/storage.

Rating Storage:

Store ratings in a database, linking each rating to the page URL and user ID.

Ensure data privacy and compliance (e.g., GDPR).

Rating Display:

Show average rating and number of ratings per page.

Users can view their own rating for a page when using the same device and browser.

Security:
