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

B is a concrete, functional simplification: it removes dead/unused parameters and a redundant card-render/morph path from a real, in-use handler, tightening the vote-compare success flow. A merely adds a long planning markdown document plus an unused RouteContext wrapper that isn't wired into any call site, providing speculative scaffolding rather than working improvements.
