openai/gpt-5.2-chat → A (3:2)

Commit A delivers a user-facing feature that enables unpinning directly from ranked child group rows, integrating backend rendering changes, form wiring, CSS updates across themes, and expanded end-to-end browser tests. It meaningfully extends interaction capabilities and modifies multiple layers of the stack. Commit B improves visual ranking fidelity with a better gradient normalization algorithm and solid unit tests, but its scope is confined to styling logic within a single module. Overall, A represents a broader and more impactful contribution.
