+
+### Sidebar Component
+
+**File:** `src/lib/components/layout/Sidebar.svelte`
+
+**States:**
+- `expanded` (240px) — Full navigation with labels
+- `collapsed` (64px) — Icons only
+- `hidden` (0px) — Completely hidden (mobile drawer)
+
+**Features:**
+- Toggle button in header
+- Section headers: PLANNING, REPORTS, ADMIN
+- Role-based visibility (ADMIN section for superuser only)
+- Active route highlighting
+- Dark mode toggle at bottom
+- Keyboard shortcut: `Cmd/Ctrl + \` to toggle
+
+**Responsive Behavior:**
+
+| Breakpoint | Default State | Toggle Method |
+|------------|---------------|---------------|
+| ≥1280px | expanded | Manual |
+| 1024-1279px | collapsed | Manual |
+| <1024px | hidden | Hamburger menu (drawer overlay) |
+
+### TopBar Component
+
+**File:** `src/lib/components/layout/TopBar.svelte`
+
+**Elements:**
+- Left: Hamburger menu (mobile only)
+- Center: Breadcrumbs
+- Right: Month selector, User menu
+
+**Global Month Selector:**
+```typescript
+// src/lib/stores/period.ts
+import { writable } from 'svelte/store';
+
+export const selectedMonth = writable<string>(getCurrentMonth());
+
+function getCurrentMonth(): string {
+  const now = new Date();
+  return `${now.getFullYear()}-${String(now.getMonth() + 1).padStart(2, '0')}`;
+}
+
+export function setMonth(month: string): void {
+  selectedMonth.set(month);
+}
+```
+
+### Layout Store
+
+**File:** `src/lib/stores/layout.ts`
+
+```typescript
+// src/lib/stores/layout.ts
+import { writable } from 'svelte/store';
+import { browser } from '$app/environment';
+
+export type SidebarState = 'expanded' | 'collapsed' | 'hidden';
+export type Theme = 'light' | 'dark';
+
+function createLayoutStore() {
+  const defaultSidebar: SidebarState = browser && window.innerWidth >= 1280 
+    ? 'expanded' 
+    : browser && window.innerWidth >= 1024 
+      ? 'collapsed' 
+      : 'hidden';
+  
+  const storedSidebar = browser 
+    ? (localStorage.getItem('headroom_sidebar_state') as SidebarState) || defaultSidebar 
+    : defaultSidebar;
+  
+  const storedTheme = browser 
+    ? (localStorage.getItem('headroom_theme') as Theme) || 'light' 
+    : 'light';
+  
+  const sidebarState = writable<SidebarState>(storedSidebar);
+  const theme = writable<Theme>(storedTheme);
+  
+  return {
+    sidebarState: { subscribe: sidebarState.subscribe },
+    theme: { subscribe: theme.subscribe },
+    toggleSidebar: () => {
+      sidebarState.update(current => {
+        const next = current === 'expanded' ? 'collapsed' : 
+                     current === 'collapsed' ? 'hidden' : 'expanded';
+        if (browser) localStorage.setItem('headroom_sidebar_state', next);
+        return next;
+      });
+    },
+    setTheme: (newTheme: Theme) => {
+      theme.set(newTheme);
+      if (browser) localStorage.setItem('headroom_theme', newTheme);
+    }
+  };
+}
+
+export const layoutStore = createLayoutStore();
+```
+
+### Navigation Configuration
+
+**File:** `src/lib/config/navigation.ts`
+
+```typescript
+// src/lib/config/navigation.ts
+import type { NavSection } from '$lib/types/layout';
+
+export const navigationSections: NavSection[] = [
+  {
+    title: 'PLANNING',
+    items: [
+      { label: 'Dashboard', href: '/dashboard', icon: 'layout-dashboard' },
+      { label: 'Team Members', href: '/team-members', icon: 'users' },
+      { label: 'Projects', href: '/projects', icon: 'folder' },
+      { label: 'Allocations', href: '/allocations', icon: 'calendar' },
+      { label: 'Actuals', href: '/actuals', icon: 'check-circle' },
+    ]
+  },
+  {
+    title: 'REPORTS',
+    items: [
+      { label: 'Forecast', href: '/reports/forecast', icon: 'trending-up' },
+      { label: 'Utilization', href: '/reports/utilization', icon: 'bar-chart-2' },
+      { label: 'Costs', href: '/reports/costs', icon: 'dollar-sign' },
+      { label: 'Variance', href: '/reports/variance', icon: 'alert-circle' },
+      { label: 'Allocation Matrix', href: '/reports/allocation', icon: 'grid-3x3' },
+    ]
+  },
+  {
+    title: 'ADMIN',
+    roles: ['superuser'],
+    items: [
+      { label: 'Settings', href: '/settings', icon: 'settings' },
+      { label: 'Master Data', href: '/master-data', icon: 'database' },
+    ]
+  },
+];
+```
+
+### Theme System
+
+**Implementation:**
+- DaisyUI theme switching via `data-theme` attribute on `<html>` element
+- Light theme: `light` (DaisyUI default)
+- Dark theme: `dark` or `business`
+- Persisted to localStorage
+- Respects system preference on first visit
+
+```typescript
+// Theme toggle effect
+$effect(() => {
+  if (browser) {
+    document.documentElement.setAttribute('data-theme', $theme);
+  }
+});
+```
+
+### Route Layout Integration
+
+**File:** `src/routes/+layout.svelte`
+
+```svelte
+<script lang="ts">
+  import AppLayout from '$lib/components/layout/AppLayout.svelte';
+  import { page } from '$app/stores';
+  
+  // Pages without AppLayout
+  const publicPages = ['/login', '/auth'];
+  $: isPublicPage = publicPages.some(p => $page.url.pathname.startsWith(p));
+</script>
+
+{#if isPublicPage}
+  <slot />
+{:else}
+  <AppLayout>
+    <slot />
+  </AppLayout>
+{/if}
+```
+
+### Data Density Patterns
+
+**Table Configurations (DaisyUI):**
+
+| View | Classes | Purpose |
+|------|---------|---------|
+| Allocation Matrix | `table table-compact table-pin-rows table-pin-cols` | Max density, pinned header/first column |
+| Projects List | `table table-zebra table-pin-rows` | Readability, pinned header |
+| Team Members | `table table-zebra` | Standard readability |
+| Reports | `table table-compact table-pin-rows` | Dense data, pinned header |
+
+### Accessibility Requirements
+
+1. **Keyboard Navigation:**
+   - `Tab` through sidebar items
+   - `Enter/Space` to activate
+   - `Escape` to close mobile drawer
+   - `Cmd/Ctrl + \` to toggle sidebar
+
+2. **ARIA Attributes:**
+   - `aria-expanded` on sidebar toggle
+   - `aria-current="page"` on active nav item
+   - `role="navigation"` on sidebar
+   - `role="main"` on content area
+
+3. **Focus Management:**
+   - Focus trap in mobile drawer
+   - Focus restored on drawer close

+## UI Layout Decisions
+
+**Date:** February 18, 2026  
+**Context:** After initial authentication implementation, reviewed login page UI and decided to establish a comprehensive layout system.
+
+### Problem Statement
+
+The initial UI implementation used a simple top-navbar pattern without a standardized layout system. For a data-dense resource planning application, this approach would not scale well.
+
+### Design Direction
+
+**Aesthetic Spectrum Decision:**
+- Target: **70% Data-Dense | 30% Utilitarian**
+- Reference Apps: **Obsidian** (minimal chrome, content-first) + **Jira** (hierarchical sidebar, dense tables)
+
+### Core Layout Decisions
+
+| Decision | Choice | Rationale |
+|----------|--------|-----------|
+| **Sidebar** | Collapsible (full ↔ icons-only ↔ hidden) | Preserves screen real estate for low-resolution displays; sidebar should not eat productive space |
+| **Month Selector** | Global (in top bar) | Allocation and actuals views are month-centric; affects all views |
+| **Default Theme** | Light mode | Starting simple; dark mode available as toggle |
+| **Icon Library** | **Lucide Svelte** | Modern, more icon variety, consistent with Svelte ecosystem |
+| **UI Framework** | **DaisyUI-first** (no shadcn-svelte) | Already have it, excellent for business apps, use ~80% of its potential |
+| **Navigation Pattern** | Persistent sidebar + top bar | Obsidian/Jira style; sectioned navigation (Planning, Reports, Admin) |
+

+### Responsive Behavior
+
+| Breakpoint | Sidebar Behavior | Toggle |
+|------------|------------------|--------|
+| ≥1280px (xl) | Expanded by default | Manual toggle only |
+| 1024-1279px (lg) | Collapsed by default | Manual toggle only |
+| 768-1023px (md) | Hidden (drawer overlay) | Hamburger menu |
+| <768px (sm) | Hidden (drawer overlay) | Hamburger menu |
+
+### Implementation Approach
+
+**Phased Changes:**
+1. `p00-api-documentation` — Add Scribe annotations to all controllers
+2. `p01-ui-foundation` — Types, stores, Lucide setup, theme system
+3. `p02-app-layout` — AppLayout, Sidebar, TopBar, Breadcrumbs
+4. `p03-dashboard-enhancement` — Dashboard with stat cards
+5. `p04-content-patterns` — DataTable, StatCard, FilterBar, EmptyState, LoadingState
+6. `p05-page-migrations` — Migrate remaining pages incrementally
+

+### Key Quotes from Discussion
+
+> "I like a collapsible sidebar, because some people use very low screen resolution which will limit the real estate to play around with. Sidebar should not eat up the productive space."
+
+> "Make [month selector] global."
+
+> "Light mode for now."
+
+> "I lean more towards data-dense. How about keeping it 30-70 (utilitarian-data-dense)?"
+
+> "Use Lucide."

 **Goal**: Create all failing tests from spec scenarios
 
 #### E2E Tests (Playwright)
-- [x] 1.1.1 Write E2E test: Successful login issues JWT tokens (skipped - infra issue)
-- [x] 1.1.2 Write E2E test: Invalid credentials rejected (skipped - infra issue)
-- [x] 1.1.3 Write E2E test: Missing email or password validation (skipped - infra issue)
-- [x] 1.1.4 Write E2E test: Token refresh with valid refresh token (skipped - infra issue)
-- [x] 1.1.5 Write E2E test: Token refresh with invalid/expired token rejected (skipped - infra issue)
-- [x] 1.1.6 Write E2E test: Logout invalidates refresh token (skipped - infra issue)
-- [x] 1.1.7 Write E2E test: Access protected route with valid token (skipped - infra issue)
-- [x] 1.1.8 Write E2E test: Access protected route without token rejected (skipped - infra issue)
-- [x] 1.1.9 Write E2E test: Access protected route with expired token rejected (skipped - infra issue)
-- [x] 1.1.10 Write E2E test: Token auto-refresh on 401 response (skipped - infra issue)
+- [x] 1.1.1 E2E test: Successful login issues JWT tokens ✓

+- [x] 1.1.10 E2E test: Token auto-refresh on 401 response ✓
 
-**NOTE**: E2E tests are written but skipped due to project architecture issue. The frontend is a Vite+Svelte project (not SvelteKit), so file-based routing doesn't work. Tests documented and ready for when architecture is updated.
+**STATUS**: 8/11 E2E tests passing (73%). Infrastructure issues resolved - frontend IS using SvelteKit with file-based routing. Remaining failures are timing/race condition issues in auth state synchronization after page reload.
 
 #### API Tests (Pest)
 - [x] 1.1.11 Write API test: POST /api/auth/login with valid credentials (->todo)

+# Design: API Documentation with Scribe
+
+## Technical Approach
+
+### Scribe Configuration
+File: `config/scribe.php`
+
+```php
+return [
+    'title' => 'Headroom API',
+    'description' => 'Resource planning and capacity management API',
+    'base_url' => env('APP_URL') . '/api',
+    'auth' => [
+        'enabled' => true,
+        'default' => true,
+        'in' => 'bearer',
+        'use_value' => 'Bearer {token}',
+    ],
+    'routes' => [
+        [
+            'match' => ['api/*'],
+            'include' => [],
+            'exclude' => [],
+        ],
+    ],
+];
+```
+
+### Annotation Patterns
+
+#### Authentication Endpoint Example
+```php
+/**
+ * @group Authentication
+ * 
+ * Authenticate user and issue JWT tokens.
+ * 
+ * @bodyParam email string required User's email address. Example: user@example.com
+ * @bodyParam password string required User's password. Example: secret123
+ * 
+ * @response 200 {
+ *   "data": {
+ *     "access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+ *     "refresh_token": "abc123def456...",
+ *     "token_type": "bearer",
+ *     "expires_in": 3600
+ *   }
+ * }
+ * @response 401 {
+ *   "message": "Invalid credentials",
+ *   "errors": {
+ *     "email": ["These credentials do not match our records."]
+ *   }
+ * }
+ * @response 422 {
+ *   "message": "Validation failed",
+ *   "errors": {
+ *     "email": ["The email field is required."],
+ *     "password": ["The password field is required."]
+ *   }
+ * }
+ */
+public function login(LoginRequest $request): JsonResponse
+```
+
+#### CRUD Endpoint Example
+```php
+/**
+ * @group Team Members
+ * @authenticated
+ * 
+ * List all team members with optional filters.
+ * 
+ * @queryParam active boolean Filter by active status. Example: true
+ * @queryParam role_id int Filter by role ID. Example: 1
+ * 
+ * @response 200 {
+ *   "data": [
+ *     {
+ *       "id": "550e8400-e29b-41d4-a716-446655440000",
+ *       "name": "Alice Johnson",
+ *       "role": {"id": 1, "name": "Frontend Dev"},
+ *       "hourly_rate": 75.00,
+ *       "active": true
+ *     }
+ *   ],
+ *   "meta": {"total": 10}
+ * }
+ */
+public function index(Request $request): JsonResponse

+
+### Authentication Documentation
+Include a dedicated section explaining:
+1. How to obtain tokens (login endpoint)
+2. How to use tokens (Authorization: Bearer {token})
+3. Token refresh flow
+4. Token expiration (60 min access, 7 day refresh)
+
+## Implementation Order
+
+1. Configure Scribe (`config/scribe.php`)
+2. Annotate AuthController (most critical, used by all)
+3. Annotate TeamMemberController
+4. Annotate ProjectController
+5. Annotate AllocationController
+6. Annotate ActualController
+7. Annotate CapacityController
+8. Annotate ReportController
+9. Annotate MasterDataController
+10. Generate documentation (`php artisan scribe:generate`)
+11. Verify SwaggerUI at `/api/documentation`

+# Proposal: API Documentation with Scribe
+
+## Overview
+Add comprehensive API documentation annotations to all Laravel controllers using Laravel Scribe. This enables auto-generated SwaggerUI documentation accessible at `/api/documentation`.
+
+## Goals
+- Annotate ALL existing API controllers with Scribe annotations
+- Generate browsable API documentation
+- Ensure documentation stays in sync with implementation
+- Enable frontend developers to reference accurate API specs
+
+## Non-Goals
+- Creating new API endpoints
+- Modifying existing API responses
+- Setting up API versioning
+
+## Priority
+**HIGH** - This is a prerequisite for UI changes (p01-p05) to ensure API contracts are documented.
+
+## Scope
+
+### Controllers to Document
+1. **AuthController** - Login, logout, token refresh endpoints
+2. **TeamMemberController** - CRUD for team members
+3. **ProjectController** - CRUD, status transitions, estimates
+4. **AllocationController** - CRUD, bulk operations, matrix view
+5. **ActualController** - CRUD, logging hours
+6. **CapacityController** - Capacity calculations, holidays, PTO
+7. **ReportController** - Forecast, utilization, costs, variance reports
+8. **MasterDataController** - Roles, statuses, types management
+
+### Annotations Required
+Each endpoint must have:
+- `@group` - Logical grouping (e.g., "Authentication", "Team Members")
+- `@authenticated` - For protected endpoints
+- `@bodyParam` - Request body parameters
+- `@response` - Example success response
+- `@response 401|403|422` - Error responses
+
+## Success Criteria
+- [ ] All controllers have Scribe annotations
+- [ ] `php artisan scribe:generate` runs without errors
+- [ ] SwaggerUI accessible at `/api/documentation`
+- [ ] All endpoints documented with request/response examples
+- [ ] Authentication section explains JWT flow
+
+## Estimated Effort
+2-3 hours
+
+## Dependencies
+- Existing Laravel backend with controllers
+- tymon/jwt-auth for authentication examples
+
+## References
+- docs/headroom-decision-log.md → Architecture Decisions → API Documentation
+- openspec/config.yaml → documentation rules

+# Proposal: UI Foundation
+
+## Overview
+Establish the foundational UI building blocks for Headroom's layout system. This includes types, stores, icon library, and theme configuration that all subsequent UI changes will depend on.
+
+## Goals
+- Install and configure Lucide icons for Svelte
+- Create layout-related TypeScript types
+- Create layout/period stores for state management
+- Set up theme system (light/dark mode with persistence)
+- Define navigation configuration structure
+
+## Non-Goals
+- Creating visual components (done in p02-app-layout)
+- Building actual pages (done in p03+)
+- API documentation (done in p00-api-documentation)
+
+## Priority
+**HIGH** - Foundation for all UI changes (p02-p05 depend on this)
+
+## Scope
+
+### Icon Library
+- Install `lucide-svelte` package
+- Create icon usage patterns/documentation
+- Replace existing inline SVGs where applicable
+
+### Types
+- `SidebarState` - 'expanded' | 'collapsed' | 'hidden'
+- `NavItem` - label, href, icon, roles
+- `NavSection` - title, items, roles (for role-based visibility)
+
+### Stores
+- `layoutStore` - sidebar state, theme preference
+- `periodStore` - global month/period selection
+
+### Theme System
+- DaisyUI theme switching via `data-theme` attribute
+- Light mode default ("light" theme)
+- Dark mode option ("dark" theme)
+- Persistence to localStorage
+- Respect system preference on first visit
+
+### Navigation Configuration
+- Centralized navigation structure
+- Role-based visibility for admin section
+
+## Success Criteria
+- [ ] Lucide icons installed and working
+- [ ] Types defined and exported
+- [ ] Stores created with localStorage persistence
+- [ ] Theme toggle functional
+- [ ] Navigation config exported
+- [ ] All tests pass
+
+## Estimated Effort
+1-2 hours
+
+## Dependencies
+- None (foundation change)
+
+## Blocks
+- p02-app-layout
+- p03-dashboard-enhancement
+- p04-content-patterns
+- p05-page-migrations

+# Proposal: App Layout
+
+## Overview
+Create the main application layout components including collapsible sidebar, top bar, and breadcrumbs. This establishes the structural skeleton that all authenticated pages will use.
+
+## Goals
+- Create AppLayout component that wraps dashboard pages
+- Create Sidebar component with three states (expanded, collapsed, hidden)
+- Create TopBar component with breadcrumbs, month selector, user menu
+- Create Breadcrumbs component with auto-generation from route
+- Implement responsive behavior (drawer on mobile)
+- Update root layout to conditionally use AppLayout
+
+## Non-Goals
+- Content components (DataTable, StatCard) - done in p04
+- Dashboard page implementation - done in p03
+- Page migrations - done in p05
+
+## Priority
+**HIGH** - Required before any page can use new layout
+
+## Scope
+
+### AppLayout Component
+- Wraps Sidebar + Main content area
+- Handles responsive behavior
+- Slot for page content
+- Skip for public pages (login)
+
+### Sidebar Component
+- Three visual states: expanded (240px), collapsed (64px), hidden (0px)
+- Collapsible sections (Planning, Reports, Admin)
+- Active route highlighting
+- Role-based visibility (admin section)
+- Dark mode toggle at bottom
+- Keyboard shortcut: Cmd/Ctrl + \
+
+### TopBar Component
+- Left: Breadcrumbs
+- Center: Page title (optional)
+- Right: Month selector, User menu
+- Mobile: Hamburger toggle
+- Sticky positioning
+
+### Breadcrumbs Component
+- Auto-generate from route path
+- Home icon for root
+- DaisyUI breadcrumbs styling
+
+## Success Criteria
+- [ ] AppLayout renders correctly
+- [ ] Sidebar toggles between states
+- [ ] TopBar displays correctly
+- [ ] Breadcrumbs auto-generate
+- [ ] Responsive drawer works on mobile
+- [ ] Login page exempt from layout
+- [ ] All tests pass
+
+## Estimated Effort
+4-6 hours
+
+## Dependencies
+- p01-ui-foundation (types, stores, icons, navigation config)
+
+## Blocks
+- p03-dashboard-enhancement
+- p04-content-patterns
+- p05-page-migrations

+## Usage Examples
+
+### DataTable Usage
+```svelte
+<script>
+  import DataTable from '$lib/components/common/DataTable.svelte';
+  import type { ColumnDef } from '@tanstack/svelte-table';
+
+  const columns: ColumnDef<TeamMember>[] = [
+    { accessorKey: 'name', header: 'Name' },
+    { accessorKey: 'role', header: 'Role' },
+    { accessorKey: 'hourlyRate', header: 'Rate' },
+  ];
+
+  let data = $state([]);
+  let loading = $state(true);
+
+  onMount(async () => {
+    data = await fetchTeamMembers();
+    loading = false;
+  });
+</script>
+
+<DataTable 
+  {data} 
+  {columns} 
+  {loading}
+  emptyTitle="No team members"
+  emptyDescription="Add your first team member to get started."
+  onRowClick={(row) => navigate(`/team-members/${row.id}`)}
+/>
+```
+
+### FilterBar Usage
+```svelte
+<script>
+  import FilterBar from '$lib/components/common/FilterBar.svelte';
+
+  let search = $state('');
+  let statusFilter = $state('all');
+
+  const statuses = [
+    { value: 'all', label: 'All Statuses' },
+    { value: 'active', label: 'Active' },
+    { value: 'inactive', label: 'Inactive' },
+  ];
+</script>
+
+<FilterBar 
+  searchValue={search}
+  searchPlaceholder="Search team members..."
+  onSearchChange={(v) => search = v}
+>
+  <select 
+    class="select select-sm"
+    bind:value={statusFilter}
+  >
+    {#each statuses as status}
+      <option value={status.value}>{status.label}</option>

+# Proposal: Content Patterns
+
+## Overview
+Create reusable content components for data-dense views: DataTable, FilterBar, EmptyState, and LoadingState.
+
+## Goals
+- Create DataTable component wrapping TanStack Table with DaisyUI styling
+- Create FilterBar component for reusable filter patterns
+- Create EmptyState component for no-data placeholders
+- Create LoadingState component with skeleton patterns
+
+## Non-Goals
+- Page implementations (done in p05)
+- Specific business logic
+
+## Priority
+**MEDIUM** - Reusable patterns for pages
+
+## Scope
+
+### DataTable Component
+- Wraps @tanstack/svelte-table
+- DaisyUI table styling
+- Sorting support
+- Pagination support
+- Row selection (optional)
+- Loading state
+- Empty state integration
+
+### FilterBar Component
+- Search input
+- Filter dropdowns
+- Date range picker integration
+- Clear filters button
+- Slot for custom filters
+
+### EmptyState Component
+- Icon display
+- Title and description
+- Optional action button
+- Consistent styling
+
+### LoadingState Component
+- Skeleton patterns for different content types
+- Table skeleton
+- Card skeleton
+- Text skeleton
+
+## Success Criteria
+- [ ] DataTable created with TanStack integration
+- [ ] FilterBar created with search and dropdowns
+- [ ] EmptyState created with icon and action
+- [ ] LoadingState created with skeletons
+- [ ] All tests pass
+
+## Estimated Effort
+3-4 hours
+
+## Dependencies
+- p02-app-layout
+- p03-dashboard-enhancement (can start in parallel)
+
+## Blocks
+- p05-page-migrations

+# Tasks: Content Patterns
+
+## Phase 1: LoadingState Component
+
+- [ ] 4.1 Create `src/lib/components/common/LoadingState.svelte`
+- [ ] 4.2 Add type prop ('table' | 'card' | 'text' | 'list')
+- [ ] 4.3 Add rows prop for table/list count
+- [ ] 4.4 Add columns prop for table columns
+- [ ] 4.5 Implement table skeleton
+- [ ] 4.6 Implement card skeleton
+- [ ] 4.7 Implement list skeleton
+- [ ] 4.8 Implement text skeleton
+- [ ] 4.9 Write component test: renders each type
+
+## Phase 2: EmptyState Component
+
+- [ ] 4.10 Create `src/lib/components/common/EmptyState.svelte`
+- [ ] 4.11 Add title prop (default: "No data")
+- [ ] 4.12 Add description prop
+- [ ] 4.13 Add icon prop (default: Inbox)
+- [ ] 4.14 Add children snippet for action button
+- [ ] 4.15 Style with centered layout
+- [ ] 4.16 Write component test: renders with defaults
+- [ ] 4.17 Write component test: renders with custom icon

+# Design: Page Migrations
+
+## Migration Strategy
+
+### Approach
+1. Create new page using layout components
+2. Add route (+page.svelte)
+3. Add page load function (+page.ts) for data fetching
+4. Integrate with existing API endpoints
+5. Test and verify
+6. Remove old components

+# Proposal: Page Migrations
+
+## Overview
+Migrate existing pages to use the new layout system and content patterns, completing the UI refactor.
+
+## Goals
+- Migrate Team Members page with DataTable
+- Migrate Projects page with status workflow
+- Create placeholder pages for remaining capabilities
+- Remove old Navigation component
+- Ensure all E2E tests pass
+
+## Non-Goals
+- New functionality (just layout migration)
+- Backend API work
+
+## Priority
+**MEDIUM** - Complete the UI refactor
+
+## Scope
+
+### Pages to Migrate
+1. **Team Members** (`/team-members`)
+   - DataTable with CRUD
+   - FilterBar with search and status filter
+   - Inline edit or modal for create/edit
+
+2. **Projects** (`/projects`)
+   - DataTable with status badges
+   - FilterBar with status/type filters
+   - Status workflow indicators
+
+3. **Allocations** (`/allocations`)
+   - Allocation matrix view (new component)
+   - Month navigation
+   - Inline editing
+
+### Placeholder Pages
+- `/actuals` - Basic page with coming soon
+- `/reports/*` - Basic pages with coming soon
+- `/settings` - Basic page for admin
+- `/master-data` - Basic page for admin
+
+### Cleanup
+- Remove old `Navigation.svelte`
+- Update any remaining references
+
+## Success Criteria
+- [ ] Team Members page migrated
+- [ ] Projects page migrated
+- [ ] Placeholder pages created
+- [ ] Old Navigation removed
+- [ ] All E2E tests pass
+- [ ] No console errors
+
+## Estimated Effort
+4-6 hours
+
+## Dependencies
+- p02-app-layout
+- p03-dashboard-enhancement
+- p04-content-patterns
+
+## Blocks
+- None (final change in UI refactor sequence)

     - Zero linting errors (Laravel Pint, ESLint, Prettier)
     - API documentation must be up-to-date (Scribe generation)
   
+  # Documentation Standards
+  documentation:
+    - API documentation (Scribe annotations) is MANDATORY for all controllers
+    - Every endpoint must have @group, @authenticated (if protected), @response annotations
+    - Update docs/ when making significant decisions (decision-log.md, architecture.md)
+    - Document new dependencies in both config.yaml techstack AND design.md

+  # Workflow Loops
+  workflow:
+    - Follow capability-based workflow: Test → Implement → Refactor → Document
+    - Do NOT skip phases - each phase has a specific commit
+    - Run full test suite after EACH implementation commit
+    - Fix failing tests before moving to next scenario
+    - API documentation (Scribe) is generated in Phase 4 (Document)
+    - Loop through scenarios one at a time (not all at once)
+  
+  # UI Standards (70% data-dense, 30% utilitarian)
+  ui_standards:
+    - Use Lucide Svelte for ALL icons (no inline SVGs, no other icon libraries)
+    - DaisyUI-first approach - use DaisyUI components before building custom
+    - Sidebar pattern: Collapsible (expanded ↔ collapsed ↔ hidden)
+    - Global month selector in top bar (affects all views)
+    - Light mode default, dark mode available via toggle
+    - Table density: Use table-compact for data-heavy views
+    - Reference apps: Obsidian (minimal chrome) + Jira (hierarchical sidebar)
+  
+  # Component Patterns
+  component_patterns:
+    layout:
+      - AppLayout.svelte: Main wrapper with sidebar + content area
+      - Sidebar.svelte: Collapsible navigation with sections
+      - TopBar.svelte: Breadcrumbs, month selector, user menu
+      - Breadcrumbs.svelte: Auto-generated from route
+      - PageHeader.svelte: Page title + action buttons slot
+    state:
+      - layoutStore: sidebarState ('expanded'|'collapsed'|'hidden'), theme
+      - periodStore: selectedMonth (global YYYY-MM format)
+      - Persist user preferences to localStorage
+    navigation:
+      - Sections: PLANNING, REPORTS, ADMIN
+      - ADMIN section visible only to superuser role
+      - Active route highlighting required
+  
+  # Accessibility Requirements
+  accessibility:
+    - Keyboard navigation: Tab through sidebar, Enter/Space to activate
+    - Escape to close mobile drawer
+    - Cmd/Ctrl + \ to toggle sidebar (desktop)
+    - ARIA: aria-expanded on sidebar toggle, aria-current="page" on active nav
+    - Focus trap in mobile drawer
+    - Focus restored on drawer close
+    - All form inputs must have associated labels
+  
+  # Responsive Design
+  responsive:
+    - ≥1280px (xl): Sidebar expanded by default, manual toggle
+    - 1024-1279px (lg): Sidebar collapsed by default, manual toggle
+    - 768-1023px (md): Sidebar hidden, hamburger menu (drawer overlay)
+    - <768px (sm): Sidebar hidden, hamburger menu (drawer overlay)
+    - Mobile drawer: Full-height overlay with backdrop
+    - Close drawer on route change (mobile)
+  
+  # State Management Patterns
+  state_management:
+    - Use Svelte stores for UI state only (not business data)
+    - Business data comes from API (no client-side caching beyond DaisyUI)
+    - Stores: auth, layout, period
+    - localStorage keys: headroom_access_token, headroom_refresh_token, 
+                         headroom_sidebar_state, headroom_theme
+    - Store files go in src/lib/stores/

   proposal:
     - Include clear Goals and Non-Goals sections
     - Reference the 4 personas (Superuser, Manager, Developer, Top Brass)
