 - [Phase 11-polish-responsiveness]: FieldRenderer select uses focus-visible:ring-2 (not focus:ring-2) for keyboard-only ring on selects
 - [Phase 11-polish-responsiveness]: CSS-only reduced-motion guard via @media (prefers-reduced-motion: reduce) — no JS listener needed
 - [Phase 11-polish-responsiveness]: key={state.currentStep} on step wrapper forces React remount triggering CSS animation from initial state
+- [Phase 12-dark-mode-visibility-fixes]: bg-surface-container text-on-surface added to FieldRenderer select className — semantic tokens ensure correct rendering in both light and dark themes without dark: prefix

+### Roadmap Evolution

+- Phase 12 added: Dark mode visibility fixes
+- Phase 13 added: Add remaining RClone remotes
