Side A delivers functional improvements to the vote-compare workflow: it adds a fullscreen chromeless layout, morphs the newly created vote preview after submission, normalizes and sorts edge-history ratios relative to the displayed left/right order, and includes tests covering the new sorting behavior and browser interactions. Side B mainly removes theme support while introducing cleaner browse URLs (`/~/...`) and helper methods like `browse_href`, which is useful but also deletes existing functionality and is narrower in long-term impact than the end-to-end UI and correctness improvements in Side A.
