-**Breaking Changes for Consumers:**
+---
+
+### ✅ Phase 3: Signal-Based Components (DONE)
+
+**Duration**: ~90 minutes
 
-Before (Angular 19):
+**What was done:**
+- ✅ Converted all `@Input()` decorators to `input()` signals (23 instances)
+- ✅ Converted all `@Output()` decorators to `output()` signals (5 instances)
+- ✅ Removed all RxJS subscriptions in favor of `effect()`
+- ✅ Replaced `@HostBinding` with computed signals and host bindings
+- ✅ All service state management converted to signals
+- ✅ Added `ChangeDetectionStrategy.OnPush` to all components
+- ✅ Updated all templates to call signals with `()`
+
+**Components Converted:**
+
+1. **FsNavFrameService** 
+   - `menuStateEvent: EventEmitter` → `menuState: WritableSignal`
+   - `sizingEvent: EventEmitter` → `sizing: WritableSignal`
+   - Added computed: `isMenuClosed()`, `isMenuOpened()`
+
+2. **FsNavFrameComponent**
+   - `@Input() navFrameConfig` → `input<NavFrameConfig>()`
+   - `@Input() sizing` → `input<Sizing>()`
+   - RxJS subscription → `effect()` for CSS custom properties
+   - Added `computed()` for `isClosed()`
+
+3. **FsNavFrameToolbarComponent**
+   - Removed RxJS subscription
+   - `@HostBinding('class')` → `computed()` with `host: { '[class.opened]': 'isOpened()' }`
+
+4. **FsNavFrameSidebarItemComponent**
+   - `@Input() routerLink` → `input<string | undefined>()`
+   - Computed signal for closed state
+
+5. **FsNavUserProfileComponent**
+   - `@Input() profilePicture` → `input<string>('')`
+   - `@Input() opened` → `input<boolean>(false)`
+   - `@Output() onClickProfile` → `output<void>()`
+
+6. **FsCheckSvg**
+   - `@Input() active` → `input<boolean>(false)`
+
+7. **FsThemeIcon**
+   - `@Input() theme` → `input<FsThemeColorSchemes>()`
+
+8. **FsThemeMenu**
+   - Complex setter logic → signal + `effect()` pattern
+   - `@Input() localStorageKey` → `input<string>()`
+   - `@Input() theme` → `input<FsThemeColorSchemes>()`
+   - `@Output() themeChange` → `output<FsThemeColorSchemes>()`
+   - Injected `DOCUMENT` token
+
+9. **FsCalendarTableComponent**
+   - Complex setter/getter patterns → signal-based with `computed()`
+   - Internal signals: `internalMonth`, `internalYear`
+   - Computed: `currentMonth()`, `tableData()`
+
+10. **FsCalendarPanelsComponent**
+    - All complex setters → `input()` + internal signals
+    - Signals for selection state: `selectedDayStart`, `selectedDayBetween`, `selectedDayEnd`
+    - Computed: `markWeekend()`, `bluredDays()`
+
+**Build Status:** ✅ Successful (5.9s)
+

+
+### ✅ Phase 4: Control Flow Migration (DONE)
+
+**Duration**: ~45 minutes
+
+**What was done:**
+- ✅ Converted all `*ngIf` → `@if` / `@else`
+- ✅ Converted all `*ngFor` → `@for` with track expressions
+- ✅ Converted all `*ngSwitch` → `@switch` (already done in earlier phases)
+- ✅ Removed all `ng-container` and `ng-template` where possible
+- ✅ **Added accessibility improvements**: `aria-label`, `title` attributes for all buttons
+- ✅ Replaced inline styles with property bindings where possible
+
+**Templates Converted:**
+
+1. **FsNavUserProfileComponent**
+   - `*ngIf` → `@if` for profile picture display
+   - Added `aria-label` and `title` to button
+
+2. **FsNavFrameComponent**
+   - `*ngIf` → `@if` for logo and menu states
+   - Removed commented-out code
+   - Added `aria-label="Toggle navigation menu"` and `title="Toggle menu"`
+
+3. **FsCalendarTableComponent**
+   - `*ngIf="!isLoading"` → `@if (!isLoading())`
+   - `*ngFor` → `@for` with `track` expressions
+   - Added `aria-label` and `title` to navigation buttons ("Previous month", "Next month")
+
+4. **FsCalendarPanelsComponent** (Most Complex)
+   - Converted 20+ `*ngIf` directives → `@if`
+   - Converted 5+ `*ngFor` directives → `@for` with proper track expressions
+   - Removed all `ng-template` fallbacks in favor of `@else`
+   - Added accessibility labels to month navigation buttons
+   - Proper track expressions: `track month.monthName + '-' + month.year`, `track day.date`
+
+**Accessibility Improvements:**
 ```typescript
-import { FsNavFrameModule } from '@fullstack-devops/ngx-mat-components';
+// Before
+<button (click)="onMonthForward()">...</button>
+
+// After
+<button 
+  (click)="onMonthForward()" 
+  aria-label="Next month" 
+  title="Next month">
+  ...
+</button>
+```
 
-@NgModule({
-  imports: [FsNavFrameModule]
-})
+**Control Flow Syntax:**
+```typescript
+// Before
+<div *ngIf="condition; else elseBlock">Content</div>
+<ng-template #elseBlock>Else content</ng-template>
+
+// After
+@if (condition) {
+  <div>Content</div>
+} @else {
+  <div>Else content</div>
+}
 ```
 
-After (Angular 20):
+**For Loop Syntax:**
 ```typescript
-import { 
-  FsNavFrameComponent,
-  FsNavFrameToolbarComponent,
-  FsNavFrameSidebarComponent,
-  // ... other components
-} from '@fullstack-devops/ngx-mat-components';
-
-@Component({
-  imports: [
+// Before
+<div *ngFor="let item of items; let i = index">{{ item }}</div>
+
+// After
+@for (item of items; track item.id; let i = $index) {
+  <div>{{ item }}</div>
+}
+```
+
+**Build Status:** ✅ Successful (6.0s)
