~anthropic/claude-sonnet-latest → B (6:4)

Side B implements a real feature (fullscreen vote-compare page with morph-on-post preview card, correct ratio/sort semantics, new layout variant, CSS across three themes, updated browser test), providing tangible user-facing value. Side A is a reasonable internal refactor (Deque->List, moving vote-cap trimming to read-time) but is a smaller, more mechanical change with less lasting functional impact, and both are equally well-tested.
