 - [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
+- [Phase 12-dark-mode-visibility-fixes]: accent-[var(--r2b-warning)] arbitrary value used for ReviewStep security checkbox — accent-warning class not confirmed generated by Tailwind v4
+- [Phase 12-dark-mode-visibility-fixes]: Removed {' '} space-before-text pattern in DeploymentStep labels — replaced with flex gap-2 layout for consistent spacing
