# Dependency graph
requires:
  - phase: 09-md3-components
    provides: MD3_BTN_FILLED/OUTLINED/TEXT constants, BackendCard, StepIndicator, ThemeToggle, FieldRenderer components
  - phase: 10-content-clarity
    provides: final step component shapes and layouts
provides:
  - Mobile-responsive wizard layout (cards stack, buttons stack, step labels collapse)
  - MD3 focus-visible ring-3 indicators on all interactive elements
affects: [future UI phases, any plan touching step components or button constants]

    - "focus-visible:ring-3 focus-visible:ring-primary on standalone interactive elements"
    - "focus-visible:ring-inset on overflow-hidden button groups (ThemeToggle) to avoid clipping"

# Phase 11 Plan 01: Mobile Responsiveness & MD3 Focus Indicators Summary

**Tailwind v4 mobile-first responsive layout (card grids, stacked button rows, collapsed step labels) plus MD3 focus-visible ring-3 keyboard indicators across all wizard interactive elements**

## Performance

- **Duration:** 3 min
- **Started:** 2026-04-01T11:22:10Z
- **Completed:** 2026-04-01T11:25:12Z
- **Tasks:** 2
- **Files modified:** 9

## Accomplishments
- Backend cards container uses responsive grid (1-col on mobile, 2-col on desktop); BackendCard fills its cell with w-full
- All four step button rows stack vertically on mobile (flex-col) and go horizontal on desktop (sm:flex-row) with full-width buttons on mobile
- StepIndicator hides label text on mobile (hidden sm:block) keeping circles and connectors visible
- MD3 button constants upgraded from ring-2/50 to ring-3 for all three variants (FILLED, OUTLINED, TEXT)
- BackendCard, ThemeToggle, StepIndicator completed-step circle, and FieldRenderer tooltip buttons all have focus-visible rings

## Task Commits

Each task was committed atomically:

1. **Task 1: Mobile responsive layout** - `07f97d9` (feat)
2. **Task 2: MD3 focus-visible indicators** - `9015db5` (feat)

**Plan metadata:** (docs commit — see below)

## Files Created/Modified
- `src/styles/md3-buttons.ts` - Upgraded ring-2/primary/50 to ring-3/primary on all three constants
- `src/components/ui/BackendCard.tsx` - Added w-full and focus-visible:ring-3 to button base classes
- `src/components/ui/ThemeToggle.tsx` - Added focus-visible:ring-3 ring-inset to both selected/unselected branches
- `src/components/ui/FieldRenderer.tsx` - Select uses focus-visible:ring-2; both tooltip buttons get focus-visible:ring-2 rounded
- `src/components/wizard/BackendSelectionStep.tsx` - Responsive card grid and button row
- `src/components/wizard/RemoteConfigStep.tsx` - Responsive button row with w-full sm:w-auto
- `src/components/wizard/DeploymentStep.tsx` - Responsive button row with w-full sm:w-auto
- `src/components/wizard/ReviewStep.tsx` - Responsive button row with w-full sm:w-auto
- `src/components/wizard/StepIndicator.tsx` - hidden sm:block on all three label spans; ring-3 on completed-step circle

## Decisions Made
- ring-inset used on ThemeToggle because the container has overflow-hidden — outset ring would be clipped by the parent border
- No ring-offset-2 on BackendCard to avoid dark mode surface color mismatch (per research open question #2)
- Tooltip buttons use ring-2 (not ring-3) — they are small utility icons where a smaller ring is more appropriate
- FieldRenderer select changed from focus:ring-2 to focus-visible:ring-2 so selects behave like buttons (ring on keyboard only), not like text inputs

## 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-01 and POLISH-02 requirements satisfied
- All 202 existing tests pass — no regressions introduced
- Wizard is now mobile-usable and fully keyboard-navigable
