+# Phase 8, Plan 02: Component Color Migration Summary
+
+**63 hardcoded Tailwind color classes migrated to semantic MD3 tokens across 9 components — entire UI now responds to theme changes via CSS variable cascade with zero dark: prefixes**
+
+## Performance
+
+- **Duration:** 6 min
+- **Started:** 2026-04-01T05:03:01Z
+- **Completed:** 2026-04-01T05:09:00Z
+- **Tasks:** 2 completed (Task 3 is a human-verify checkpoint — paused)
+- **Files modified:** 9
+
+## Accomplishments
+
+- All 63 hardcoded color class occurrences removed from 9 component files (BackendCard, FieldRenderer, PasswordField, AzureAuthToggle, SftpAuthToggle, DeploymentStep, OutputBlock, RemoteConfigStep, ReviewStep)
+- Semantic tokens applied: primary family (bg-primary, text-on-primary, text-primary, border-primary, bg-primary/10, border-primary/30), surface family (bg-surface, bg-surface-container, bg-surface-variant, text-on-surface, text-on-surface-container, text-on-surface-variant), error (border-error, text-error, focus:ring-error/50), success (text-success, bg-success/10), warning (text-warning, bg-warning/10, border-warning), outline (border-outline, focus:ring-primary/50)
+- All 166 tests pass without modification (existing tests use semantic queries, not class selectors)
+- grep -rn for all hardcoded color patterns in src/components/ and src/App.tsx returns 0 matches
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Migrate UI primitives (BackendCard, FieldRenderer, PasswordField)** - `4e30f2e` (feat)
+2. **Task 2: Migrate wizard components (toggles, steps, output block)** - `1ac32ea` (feat)
+3. **Task 3: Visual verification** - checkpoint: human-verify (pending)
+
+**Plan metadata:** _(docs commit follows)_
+
+## Files Created/Modified
+
+- `src/components/ui/BackendCard.tsx` — selected/unselected card border/bg colors, name/description text colors
+- `src/components/ui/FieldRenderer.tsx` — label, required asterisk, tooltip toggle, tooltip box, input borders, focus rings, help text, error message (both select and text-input branches)
+- `src/components/ui/PasswordField.tsx` — label, tooltip toggle, tooltip box, input borders, focus ring, eye icon, help text, error message
+- `src/components/wizard/AzureAuthToggle.tsx` — segmented control border, active/inactive tab colors
+- `src/components/wizard/SftpAuthToggle.tsx` — auth method label, info tooltip toggle + box, segmented control border, active/inactive tab colors
+- `src/components/wizard/DeploymentStep.tsx` — Back and Next navigation buttons
+- `src/components/wizard/OutputBlock.tsx` — label, Copy/Download button borders, code pre background/text
+- `src/components/wizard/RemoteConfigStep.tsx` — Back and Next navigation buttons
+- `src/components/wizard/ReviewStep.tsx` — client-side notice, security warning box (bg/border/title/label), Back button, Download All ZIP button
+
+## Decisions Made
+
+- **Mechanical migration only:** Zero DOM structure changes — only className string replacements as specified by the plan's migration mapping. Ensures no regressions.
+- **Both yellow variants -> text-warning:** `text-yellow-800` (warning title) and `text-yellow-900` (warning label) both map to `text-warning`. Single token is sufficient and avoids creating artificial token variants.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] FieldRenderer text branch not fully migrated by replace_all**
+- **Found during:** Task 2 verification grep
+- **Issue:** FieldRenderer has two conditional branches (select and text) with visually identical but structurally different JSX. The `replace_all` edits during Task 1 missed the text branch's label className and tooltip paragraph because the select branch was matched first (different aria-label attribute present). Post-task grep revealed 2 remaining occurrences.
+- **Fix:** Added targeted Edit for the text branch's label (`text-gray-700` -> `text-on-surface-container`) and tooltip paragraph (`text-blue-700 bg-blue-50 border border-blue-200` -> `text-primary bg-primary/10 border border-primary/30`).
+- **Files modified:** `src/components/ui/FieldRenderer.tsx`
+- **Verification:** grep returns 0 matches after fix; 166 tests still pass
+- **Committed in:** `1ac32ea` (Task 2 commit, staged with wizard files)
+
+---
+
+**Total deviations:** 1 auto-fixed (Rule 1 - missed occurrence in dual-branch component)
+**Impact on plan:** Caught by mandatory post-migration grep check. Fix was a 2-line edit. No scope creep.
+
+## Issues Encountered
+
+- FieldRenderer's dual-branch structure (select vs text-input, both with identical tooltip JSX) caused a missed replacement when using `replace_all`. The post-migration grep verification step is confirmed mandatory for any component with if/else branches that share className strings.
+
+## User Setup Required
+
+None — no external service configuration required.
+
+## Next Phase Readiness
+
+- Zero hardcoded Tailwind color classes remain in `src/components/` and `src/App.tsx`
+- The entire UI is now driven by CSS custom properties — light/dark theme switching is fully functional via the `.dark` class on `<html>`
+- Task 3 is a human-verify checkpoint: user must visually confirm both light and dark themes render correctly in the browser (`npm run dev`, http://localhost:5173)
+- After visual approval, Phase 8 is complete (THEME-01 and THEME-02 requirements satisfied)
+- No blockers for Phase 9+ (content refinement, polish)
