openai/gpt-chat-latest → B (3:2)

Side B makes a substantive architectural improvement to the authentication flow by replacing redirect-based form handling with inline HTML fragments, extending the existing Poem JS to morph form content from non-empty responses, and refactoring the auth templates to reuse shared form markup. Side A improves the ranking UI by basing row colors on per-group score ranges instead of list position and adds focused tests, but its impact is primarily presentational, whereas Side B changes user interaction and simplifies server/client behavior for auth.
