Side B fixes a real bug (vote-compare-preview never actually morphed with the new post card) and adds working sorting/legend/fullscreen layout improvements with corresponding tests and CSS across themes. Side A is a large deletion of a complex but functioning keystroke-parser graph replaced by a much simpler paste-and-go textarea; while it simplifies the code, it removes substantial working functionality (autocomplete, DB suggestions, guides) without preserving equivalent value, making it more of a regression/simplification than a net addition of lasting value.
