  - "OutputBlock Copy/Download buttons use MD3_BTN_OUTLINED with !text-xs !px-3 !py-1.5 overrides to preserve small utility button size"

patterns-established:
  - "Tooltip button pattern: tooltip UI rendered above TextFieldMD3 component in a flex-col wrapper — keeps TextFieldMD3 self-contained"
  - "Button hierarchy: MD3_BTN_FILLED for primary forward actions (Next, Download All), MD3_BTN_OUTLINED for secondary/back actions (Back, Copy, Download)"
  - "MD3 elevation pattern: rounded-xl + shadow on cards, rounded-xl + shadow-sm on code blocks"

# Phase 9 Plan 03: MD3 Component Integration Summary

**TextFieldMD3 wired into all wizard text inputs with floating labels, MD3 filled/outlined button hierarchy applied across all 4 wizard steps, and MD3 elevation (rounded-xl + shadow) added to BackendCard and OutputBlock.**

## Performance

- **Duration:** ~25 min
- **Started:** 2026-04-01
- **Completed:** 2026-04-01
- **Tasks:** 3 (2 auto + 1 human-verify checkpoint)
- **Files modified:** 8

## Accomplishments

- All text inputs in the wizard now render MD3 floating labels via TextFieldMD3 — labels animate on focus and stay floated when a value is present
- All primary action buttons (Next, Download All) use MD3 filled pill style; all secondary actions (Back, Copy, Download) use MD3 outlined pill style
- BackendCard uses rounded-xl shape with shadow elevation; OutputBlock pre blocks use rounded-xl with shadow-sm

## Task Commits

Each task was committed atomically:

1. **Task 1: Integrate TextFieldMD3 into FieldRenderer and PasswordField** - `e560a6a` (feat)
2. **Task 2: Apply MD3 button styles and elevation across all wizard steps** - `d7a2cad` (feat)
3. **Task 3: Visual verification of complete MD3 component set** - checkpoint:human-verify — approved

## Files Created/Modified

- `src/components/ui/FieldRenderer.tsx` - Text-branch replaced with TextFieldMD3; tooltip rendered above as separate element
- `src/components/ui/PasswordField.tsx` - Rebuilt using TextFieldMD3 with show/hide toggle passed as suffix prop
- `src/components/ui/BackendCard.tsx` - rounded-xl shape + shadow hover:shadow-md elevation added
- `src/components/wizard/OutputBlock.tsx` - Pre block rounded-xl + shadow-sm; Copy/Download buttons use MD3_BTN_OUTLINED
- `src/components/wizard/BackendSelectionStep.tsx` - Next button uses MD3_BTN_FILLED
- `src/components/wizard/RemoteConfigStep.tsx` - Back uses MD3_BTN_OUTLINED, Next uses MD3_BTN_FILLED
- `src/components/wizard/DeploymentStep.tsx` - Back uses MD3_BTN_OUTLINED, Next uses MD3_BTN_FILLED
- `src/components/wizard/ReviewStep.tsx` - Back uses MD3_BTN_OUTLINED, Download All uses MD3_BTN_FILLED

## Decisions Made

1. **Tooltip position in FieldRenderer:** The tooltip button is rendered above the TextFieldMD3 component inside a flex-col wrapper. TextFieldMD3 is self-contained (manages its own label, input, helpText, error) so the tooltip is a separate concern that lives outside it.

2. **PasswordField suffix pattern:** The show/hide toggle is passed as the `suffix` prop to TextFieldMD3, which renders it inside the input container on the right. This keeps TextFieldMD3's layout contract intact while adding the toggle.

3. **OutputBlock button size overrides:** OutputBlock Copy/Download are small utility buttons. MD3_BTN_OUTLINED base classes are overridden with `!text-xs !px-3 !py-1.5` to preserve compact sizing without creating a new button variant.

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None — all 179+ tests passed after both task commits with zero regressions. User visually verified the complete MD3 component set and approved.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- COMP-01 (floating labels), COMP-02 (button hierarchy), COMP-03 (elevation) all satisfied
- Phase 9 MD3 component migration complete: primitives (09-01), StepIndicator (09-02), integration (09-03)
- Ready for Phase 10 (Content & Copy — UX text, help content, empty states)
