~x-ai/grok-latest → B (2:5)

B adds a full end-to-end capability (CopyGardenRank action, markdown formatter, UI buttons on garden headings, plus unit/integration/browser coverage and agents.md), which is reusable product value beyond styling. A is a correct, focused fix—min–max score gradients instead of ordinal position—with tight helper/tests, but it only refines existing rank-row colors rather than expanding what users can do with rankings.
