requires:
  - phase: 03-form-submit-booking
    provides: Complete booking flow end-to-end (customer → pricing → booking → confirm → success)
provides:
  - Token retry on 401/403 with auto-recovery
  - AbortController timeout 15s with Polish error messages
  - Network error detection and user-friendly messaging
  - Extended reject reason translations (6 codes)
  - Animated step transitions (form ↔ summary ↔ success)
  - Modal open/close animations (fade + scale)
  - ARIA dialog with focus trap and focus management
  - aria-live announcements for screen readers
  - CSS bug fix (orphaned media query styles)

key-decisions:
  - "Inline style.display for step visibility instead of CSS-only classes — HTML inline display:none overrides classes"
  - "Focus trap via keydown listener on overlay, filtering visible focusable elements"
  - "aria-live region appended to modal overlay for scoped announcements"

patterns-established:
  - "transitionStep(outEl, inEl, callback) pattern for animated view switching"
  - "hideStep/showStep helpers using style.display for reliable visibility control"
  - "announce() via aria-live polite region with 100ms delay for screen reader pickup"

# Phase 4 Plan 01: Polish & Integration Testing Summary

**Edge cases (token retry, timeout, network errors), animated step transitions, ARIA dialog with focus trap — formularz gotowy produkcyjnie.**

## Performance

| Metric | Value |
|--------|-------|
| Duration | ~45min |
| Tasks | 3 auto + 1 checkpoint |
| Files modified | 3 |
| Deviations | 1 (auto-fixed) |

## Acceptance Criteria Results

| Criterion | Status | Notes |
|-----------|--------|-------|
| AC-1: Wygasły token JWT | Pass | 401/403 → auto-retry 1x, user nie widzi błędu |
| AC-2: Brak dostępności pojazdu | Pass | CAR_NOT_FOUND → czytelny komunikat PL z sugestią |
| AC-3: Timeouty i błędy sieciowe | Pass | AbortController 15s, TypeError → retry → komunikat PL |
| AC-4: Animacje przejść | Pass | fade+translate form↔summary↔success, modal scale |
| AC-5: Accessibility | Pass | role=dialog, aria-modal, focus trap, focus management, aria-live |
| AC-6: Fix CSS orphaned styles | Pass | Styles przeniesione do @media (max-width: 768px) |

## Accomplishments

- Pełny error recovery: token retry, timeout 15s, network errors — formularz nigdy nie blokuje się na stałe
- Animowane przejścia między krokami: smooth fade+translate (250ms) z callback focus management
- Focus trap w modalu: Tab nie wychodzi poza modal, Escape zamyka, focus wraca na trigger
- aria-live announcements: "Ładowanie podsumowania...", "Rezerwacja potwierdzona", błędy API

## Files Modified

| File | Change | Purpose |
|------|--------|---------|
| `assets/js/carei-reservation.js` | Modified | Token retry, timeout, network errors, animacje, focus trap, aria-live |
| `assets/css/carei-reservation.css` | Modified | Modal animations, step transitions, sr-only class, CSS bug fix |
| `includes/class-elementor-widget.php` | Modified | ARIA: role=dialog, aria-modal, aria-labelledby, aria-busy, tabindex=-1 |

## Decisions Made

| Decision | Rationale | Impact |
|----------|-----------|--------|
| style.display zamiast CSS class dla visibility | HTML inline display:none nadpisuje klasy CSS | hideStep/showStep helpers operują na style.display |
| Focus na segment select po open | Pierwszy interaktywny element, najlogiczniejszy start | 350ms delay po animacji otwarcia |
| aria-live region w overlay | Scoped do modalu, nie zanieczyszcza strony | announce() z 100ms delay dla pickup przez screen readery |

## Deviations from Plan

### Summary

| Type | Count | Impact |
|------|-------|--------|
| Auto-fixed | 1 | Konieczna zmiana podejścia do visibility |

**Total impact:** Essential fix, no scope creep

### Auto-fixed Issues

**1. Inline display:none vs CSS class conflict**
- **Found during:** Checkpoint (user reported form title instead of summary)
- **Issue:** HTML elements miały `style="display:none;"` inline, a transitionStep używał klas CSS (`carei-step--hidden`) — inline style nadpisywał klasę
- **Fix:** Zmieniono na hideStep()/showStep() operujące na `el.style.display`
- **Verification:** User potwierdził poprawne działanie po fix

## Next Phase Readiness

**Ready:**
- Formularz produkcyjnie gotowy: error handling, animacje, a11y
- Booking flow end-to-end przetestowany na carei.pagedev.pl

**Concerns:**
- Penalty items filtrowane po kodzie (BRAK/BRUD/KARA) — może nie pokryć przyszłych kodów
- Brak email notification po rezerwacji (zależy od konfiguracji Softra)

**Blockers:** None
