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

A delivers a coherent feature improvement (fullscreen vote-compare layout, corrected edge-history sorting/legend, live preview morph) backed by a new unit test and updated browser test selectors, showing real engineering depth. B is a useful but narrower bugfix (centralizing hostname/base-url logic and deploy branch) that mostly replaces duplicated case statements with a shared helper, valuable but smaller in scope and lacking new tests.
