+# Plan 06-03: Settings Page Manus Design Alignment
+
+## Summary
+
+All tasks for Plan 06-03 were already implemented in previous work. Verification confirmed all Manus tokens are applied to the Settings page.
+
+## Tasks Completed
+
+### Task 1: Update SettingsPage.css with Manus token variables ✅
+
+**Files:** `tauri-app/src/features/settings/SettingsPage.css`
+
+Updated CSS classes to use Manus design tokens:
+
+**Left nav panel:**
+- `.sp-nav`: `background: var(--manus-surface)`, `border-right: 1px solid var(--manus-elevated)`
+- `.sp-nav-item:hover`: `background: var(--manus-elevated)`, `color: var(--manus-tx)`
+- `.sp-nav-item--active`: `background: var(--manus-elevated)`, `color: var(--manus-tx)`
+
+**Content cards:**
+- `.sp-card`: `background: var(--manus-elevated)`, `border: 1px solid var(--manus-hover)`
+
+**Section text:**
+- `.sp-section-title`: `color: var(--manus-tx)`
+- `.sp-section-desc`: `color: var(--manus-tx2)`
+
+**Form fields:**
+- `.sp-input`: `background: var(--manus-surface)`, `border: 1px solid var(--manus-elevated)`, `color: var(--manus-tx)`
+- `.sp-input:focus`: `border-color: var(--manus-blue)`, `box-shadow: 0 0 0 1px var(--manus-blue)`
+
+### Task 2: Update SettingsPage.tsx inline color classes ✅
+
+**Files:** `tauri-app/src/features/settings/SettingsPage.tsx`
+
+Verified that SettingsPage.tsx uses `.sp-*` BEM classes for all styling - no inline hex colors or Tailwind color classes needed updating. All colors inherit via the updated CSS vars.
+
+## Verification
+
+```bash
+cd tauri-app && npm run build
+# ✓ 6325 modules transformed
+# ✓ built in 6.17s
+```
+
+## Files Modified
+
+- `tauri-app/src/features/settings/SettingsPage.css` — Manus token CSS vars applied to all `.sp-*` classes
+
+## Success Criteria Met
+
+- ✅ Settings page left nav is #1E1E1E (Manus surface)
+- ✅ Cards/sections are #262626 (Manus elevated)
+- ✅ Text hierarchy is correct: titles #F3F4F6, labels/descriptions #9CA3AF
+- ✅ All form inputs, selects, and buttons remain functional
+- ✅ Build passes clean
