Commit A introduces substantial new functionality and parser behavior across multiple modules. It adds deterministic typed block masking, prose tokenization for item references, URL and external reference handling, stricter DSL parsing rules for braced bodies versus code fences, improved linkification, breadcrumb fixes, resolver updates, and extensive automated tests covering the new behavior. These changes affect core parsing, rendering, and external item support. Commit B is primarily a UI/layout cleanup with some CSS improvements for ranking lists and removal of an extra wrapper element in the compare page. While useful, it is much smaller in scope and impact than the parser and linkification work in Commit A.
