~x-ai/grok-latest → A (3:2)

A ships a complete, user-facing capability (CopyGardenRank + markdown formatting, UI affordances, integration/browser tests) that extends an existing pattern in a durable way. B is a worthwhile type-safety refactor (CanonicalItemUrl through resolve_item/pools, Deref on href newtypes) that cleans call sites without changing behavior, so it adds less product value than the feature.
