~anthropic/claude-sonnet-latest → B (60:40)

B is a small, focused correctness fix (enforcing valid vote ratio bounds across DSL parser, UI handler, and reducer) with targeted regression tests and a real behavioral improvement preventing degenerate/invalid votes. A is a large mechanical refactor moving code into a new types module with newtypes wrapping strings, which improves type-safety/organization but is mostly churn (renames, re-exports, moved tests) without fixing any bug or changing runtime behavior, and risks regressions across many call sites for marginal clarity gains.
