Phase 11 Plan 02: Polish & Responsiveness — Animation & Scroll-to-Error Summary

CSS step-in animation (200ms fade/slide-up) with reduced-motion guard, plus auto-scroll to first errored form field via react-hook-form onInvalidSubmit handler

Performance

• Duration: 3 min
• Started: 2026-04-01T11:28:03Z
• Completed: 2026-04-01T11:31:00Z
• Tasks: 2 (Task 2 used TDD: RED → GREEN)
• Files modified: 6

Accomplishments

• Wizard step transitions now play a 200ms opacity/translateY(8px) fade-slide animation on step change
• Users with prefers-reduced-motion enabled see zero animation (declarative CSS guard, no JS)
• BackendSelectionStep scrolls to remote-name input when form submitted with invalid/empty name
• RemoteConfigStep scrolls to the first errored field (by key) when form submitted with missing required fields
• Both scroll behaviors verified by unit tests with vi.fn() mock on Element.prototype.scrollIntoView
• Full test suite: 204 tests pass, 0 failures, 0 regressions

Task Commits

Each task was committed atomically:

1. Task 1: Step transition animation with reduced-motion guard - 9af58bc (feat)
2. Task 2 RED: Failing tests for auto-scroll to first error - 8b7daa8 (test)
3. Task 2 GREEN: Auto-scroll to first errored field implementation - 90cdeda (feat)

Plan metadata: (docs commit follows)

Note: Task 2 used TDD — separate test commit (RED) then implementation commit (GREEN).

Files Created/Modified

• src/index.css - Added --animate-step-in token in @theme, @keyframes step-in, and @media prefers-reduced-motion: reduce guard
• src/App.tsx - Step content wrapper: added key={state.currentStep} and animate-step-in class
• src/components/wizard/BackendSelectionStep.tsx - Added onInvalidSubmit scrolling to remote-name, wired to form onSubmit and handleCardClick
• src/components/wizard/BackendSelectionStep.test.tsx - Added scrollIntoView mock in beforeEach, added POLISH-04 scroll test
• src/components/wizard/RemoteConfigStep.tsx - Added FieldErrors import, onInvalidSubmit scrolling to first error key, wired to form onSubmit
• src/components/wizard/RemoteConfigStep.test.tsx - Added scrollIntoView mock in beforeEach, added POLISH-04 scroll test

Decisions Made

• CSS-only reduced-motion guard via @media (prefers-reduced-motion: reduce) — consistent with existing prefers-reduced-motion: no-preference pattern at line 45 of index.css. No JS listener.
• key={state.currentStep} on the step content wrapper div (not on step components themselves) — forces React to unmount/remount the wrapper, reliably triggering the CSS animation from its from state on every step change.
• BackendSelectionStep onInvalidSubmit uses getElementById('remote-name') directly (hardcoded) — only one validatable field exists in that step, no dynamic key needed.
• Added FieldErrors to react-hook-form imports in RemoteConfigStep (alongside existing FieldError) for typed errors parameter in onInvalidSubmit.

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• POLISH-03 (step animation) and POLISH-04 (scroll-to-error) are complete
• Phase 11 plan 02 satisfies all must_haves and success criteria
• Ready for plan 11-03 if it exists, or phase 11 completion
