Summary of Changes
Renamed Shortlist to Favorites across all code, CSS, and UI labels. Changed toggle labels to use star icons. Raised limit from 5 to 20. Decoupled favorites from compare: removing a favorite no longer updates the compare URL, Feel Lucky no longer adds to favorites, and the compare nav link is independent. localStorage persistence deferred to a follow-up.
