Record the July 17 package split as an implemented bilingual feature RFC. The decision explains why TUI and stdio have separate terminal contracts, why concrete front-door selection belongs to composition, and how the TUI preserves existing session, tool-presentation, and lifecycle ownership.
Link the deterministic dark, light, and animated demos from the RFC so the assets have an in-repository owner. Cross-link the feature and testing decisions from the package README, then regenerate the RFC index and bilingual consistency record.
