Side B strengthens type safety by threading CanonicalItemUrl through resolve_item, scope-rank computation, and pair selection, and adds Deref impls for href newtypes—reducing stringly-typed bugs and repeated CanonicalItemUrl::parse calls across the codebase. Side A is a reasonable feature swap (dropping theming for /~/ browse URLs) with tests, but it trades one feature for another rather than improving correctness or maintainability, and includes wholesale deletion of CSS/theme code that was working.
