B adds a real, reusable product stylesheet (sorter.css) that defines the app’s dark theme, layout, vote fields, rank lists, and breadcrumbs—ongoing UI value. A is mostly delete-only cleanup of already-quarantined legacy dumps (including shell-prompt paste artifacts) plus a short ideas note swap, which improves repo hygiene but does not add lasting product behavior.
