~anthropic/claude-sonnet-latest → B (3:2)

Side B fixes a real bug (undefined variable causing a NameError in a live OAuth callback path) with a minimal, correct patch. Side A is a larger UI/UX refactor (inline form morphing instead of redirect) that adds functionality but is more speculative/stylistic and carries more risk of regressions across auth flows; it's valuable but less clearly a durable correctness fix than B's crash fix.
