~x-ai/grok-latest → A (3:1)

A introduces the pinned vote HUD itself: new markup (vote_hud_form), page structure, fixed bottom bar CSS, removal of repeated item titles, and the --vote-slider-pct hook—core lasting UX design. B only polishes that HUD with fixed column widths to stop reflow and data-winner track coloring, which is useful but incremental on top of A.
