## Code Generation Steps
### Step 1: Add no-flash theme script to `index.html`
- [ ] Add inline `<script>` in `<head>` before stylesheets
- [ ] Reads `localStorage['cms-theme']`, falls back to `prefers-color-scheme`
- [ ] Applies `light` or `dark` class to `<html>` synchronously
### Step 2: Create `useTheme.ts` hook
- [ ] Create `src/hooks/useTheme.ts`
- [ ] Returns `{ theme, isDark, toggleTheme }`
- [ ] On mount: reads from `localStorage` (already set by inline script)
- [ ] `toggleTheme`: flips value, writes to `localStorage`, updates `<html>` class
### Step 3: Create `ThemeToggle.tsx`
- [ ] Create `src/components/layout/ThemeToggle.tsx`
- [ ] Uses `useTheme()` — renders `<Sun>` (dark mode) or `<Moon>` (light mode)
- [ ] `data-testid="theme-toggle"`
- [ ] i18n aria-label via `theme.switchToLight` / `theme.switchToDark`
### Step 4: Create `MobileBar.tsx`
- [ ] Create `src/components/layout/MobileBar.tsx`
- [ ] Props: `onMenuOpen: () => void`
- [ ] Visible only `< md` (`md:hidden`)
- [ ] Contains `<Menu>` icon button + app name
- [ ] `data-testid="app-mobile-bar"`, `data-testid="mobile-menu-button"`
### Step 5: Create `SidebarOverlay.tsx`
- [ ] Create `src/components/layout/SidebarOverlay.tsx`
- [ ] Props: `onClose: () => void`
- [ ] Full-screen fixed overlay with semi-transparent backdrop
- [ ] Sidebar panel slides in from left (`translate-x-0` transition, `duration-200`)
- [ ] Backdrop click calls `onClose`
- [ ] `data-testid="sidebar-overlay"`, `data-testid="sidebar-backdrop"`
### Step 6: Modify `Sidebar.tsx`
- [ ] Add `roles?: Role[]` to `NavItem` interface
- [ ] Add nav items: Settings (Owner only), Profile (all) — Dashboard, Users, CMS already exist
- [ ] Filter visible items: `NAV_ITEMS.filter(item => !item.roles || item.roles.includes(user.role))`
- [ ] Add `onClose?: () => void` prop — render close button (`<X>`) at top of sidebar on mobile
- [ ] Add `SidebarFooter` section pinned to bottom: `UserMenu` + `LanguageSwitcher` + `ThemeToggle`
- [ ] Retain `data-testid="app-sidebar"`
### Step 7: Modify `AppLayout.tsx`
- [ ] Remove `Topbar` import and render
- [ ] Add `isMenuOpen` state (`useState(false)`)
- [ ] Add `MobileBar` (triggers `setIsMenuOpen(true)`)
- [ ] Add `SidebarOverlay` (rendered when `isMenuOpen`, passes `onClose`)
- [ ] Close overlay on route change via `useEffect` watching `useLocation()`
- [ ] Desktop layout: `Sidebar` fills left, `<main>` fills right (no top bar)
### Step 8: Delete `Topbar.tsx`
- [ ] Remove `src/components/layout/Topbar.tsx`
### Step 9: Extend i18n translations
- [ ] Add to `nl/translation.json`: `theme.switchToLight`, `theme.switchToDark`, `nav.openMenu`
- [ ] Add to `en/translation.json`: same keys in English
### Step 10: Unit tests — `useTheme`
- [ ] Create `src/hooks/useTheme.test.ts`
- [ ] Initial value from localStorage / OS preference
- [ ] Toggle updates localStorage and `<html>` class
### Step 11: Unit tests — `Sidebar` role filtering
- [ ] Create `src/components/layout/Sidebar.test.tsx`
- [ ] Owner: all 5 items visible
- [ ] Administrator: Dashboard, Users, Profile visible; Settings, CMS hidden
- [ ] User: Dashboard, Profile visible; Users, Settings, CMS hidden
### Step 12: Unit tests — `AppLayout` + `MobileBar` + `SidebarOverlay`
- [ ] Create `src/components/layout/AppLayout.test.tsx`
- [ ] Mobile bar renders on small screens
- [ ] Hamburger opens overlay; backdrop click closes it
- [ ] Overlay closes on navigation
### Step 13: Final verification
- [ ] `pnpm build` — no errors
- [ ] `pnpm lint` — clean
- [ ] `pnpm test` — all tests pass (existing 29 + new)
- [ ] Dev server: verify sidebar on desktop, mobile overlay, theme toggle, role filtering
### Step 14: Commit
- [ ] Commit with message referencing US-08, US-18, US-19

## Total Steps: 14
Please answer the following questions by filling in the letter after each `[Answer]:` tag.
## Question 1: Mobile sidebar animation
When the slide-over sidebar opens on mobile, should it animate?
A) Slide in from the left with a CSS transition (recommended — feels native, Tailwind `transition-transform`)
B) Fade in (opacity transition only)
C) No animation — appear/disappear instantly
[Answer]: A
---
## Question 2: Sidebar footer layout
The sidebar footer contains UserMenu, LanguageSwitcher and ThemeToggle. How should these be presented?
A) UserMenu shows avatar/name button + dropdown (as it does now in the Topbar) — LanguageSwitcher and ThemeToggle as icon buttons next to it (recommended — compact, consistent with current UserMenu)
B) Flat list: name + email displayed as text, separate logout button, LanguageSwitcher and ThemeToggle as icon buttons below
C) Collapsed by default — only icons visible, expands on click to show labels
[Answer]: A
---
## Question 3: Unit tests scope
Which components should have unit tests?
A) All new and modified components: AppLayout, Sidebar (role filtering), MobileBar, SidebarOverlay, ThemeToggle, useTheme (recommended)
B) Only the role-filtering logic in Sidebar and the useTheme hook — skip layout wiring tests
C) No new tests for this unit — layout is covered by existing RouteGuard tests
[Answer]: A
