Production Hardening

Instructions

1. Establish the selected behavior and inspect the current diff before changing it.
2. Remove dead variants, debug affordances, temporary data, and experiment-only code.
3. Review accessibility, loading and empty states, failures, cancellation, concurrency, platform behavior, and localization where relevant.
4. Review data exposure, authorization, secrets, production mutations, and observability where relevant.
5. Add or improve tests according to regression impact; do not force a test-first rewrite of completed code.
6. Run focused checks, then the repository's broader release-relevant checks.
7. Report what is production-ready, what remains risky, and any release action still requiring approval.

Do not deploy, push, open a PR, or mutate production systems without explicit authorization.
