+# UI-Kit Layout Components
+
+This document describes the available layout components in the UI-Kit package, their purpose, and how to use them.
+
+## 1. AppShell
+
+`AppShell` is the primary layout component for admin interfaces. It provides a standard structure with:
+
+- Top navigation bar
+- Collapsible side navigation
+- Breadcrumb navigation
+- Main content area
+
+### Import
+
+```tsx
+import { AppShell } from "@org/ui-kit/layout";
+```
+
+### Props
+
+| Prop               | Type               | Default | Description                                                 |
+| ------------------ | ------------------ | ------- | ----------------------------------------------------------- |
+| `logo`             | `ReactNode`        | -       | Logo element displayed in the top-left corner               |
+| `navItems`         | `NavItem[]`        | `[]`    | Array of navigation items for the side navigation           |
+| `topNavItems`      | `ReactNode`        | -       | Custom content for the top navigation bar (buttons, links)  |
+| `userActions`      | `ReactNode`        | -       | User actions area in the top-right corner                   |
+| `breadcrumbs`      | `BreadcrumbItem[]` | -       | Array of breadcrumb items                                   |
+| `fixedHeader`      | `boolean`          | `true`  | Whether the top bar should be fixed at the top              |
+| `defaultCollapsed` | `boolean`          | `false` | Whether the side navigation is initially collapsed          |
+| `fixedWidth`       | `boolean`          | `false` | Whether content should have a fixed width (max-width 960px) |
+| `className`        | `string`           | -       | Additional CSS class name                                   |
+| `children`         | `ReactNode`        | -       | Main content to render                                      |
+
+### Responsive Behavior
+
+- **Desktop (≥1024px)**: Full layout with expanded side navigation
+- **Tablet (768-1023px)**: Side navigation can be toggled, headers stay visible
+- **Mobile (<768px)**: Side navigation collapses to icons-only rail, user actions condense
+
+### Example
+
+```tsx
+import { AppShell } from "@org/ui-kit/layout";
+import { Logo } from "@org/ui-kit/components/layout";
+import { Button } from "@org/ui-kit/components/primitives";
+
+export function AdminPage() {
+  return (
+    <AppShell
+      logo={<Logo text="My App" />}
+      navItems={[
+        {
+          id: "dashboard",
+          label: "Dashboard",
+          href: "/dashboard",
+          icon: <HomeIcon />,
+        },
+        { id: "users", label: "Users", href: "/users", icon: <UsersIcon /> },
+      ]}
+      breadcrumbs={[
+        { label: "Home", href: "/" },
+        { label: "Dashboard", isActive: true },
+      ]}
+    >
+      <h1>Dashboard Content</h1>
+      {/* Page content goes here */}
+    </AppShell>
+  );
+}
+```
+
+## 2. MinimalShell
+
+`MinimalShell` is a simplified layout for standalone pages like error screens, welcome pages, and maintenance screens.
+
+### Import

+```tsx
+import { MinimalShell } from "@org/ui-kit/layout";
+```
+
+### Props

+| `message`   | `string`    | -       | Optional subtitle or description    |
+| `image`     | `ReactNode` | -       | Optional image or icon to display   |

+| `className` | `string`    | -       | Additional CSS class name           |
+| `children`  | `ReactNode` | -       | Additional content to display       |
+
+### Example
+
+```tsx
+import { MinimalShell } from "@org/ui-kit/layout";
+import { Button } from "@org/ui-kit/components/primitives";
+import { AlertTriangleIcon } from "lucide-react";
+
+export function NotFoundPage() {
+  return (
+    <MinimalShell
+      title="404 - Page Not Found"
+      message="The page you are looking for doesn't exist or has been moved."
+      image={<AlertTriangleIcon className="h-16 w-16 text-warning" />}
+      actions={
+        <>
+          <Button intent="ghost">Contact Support</Button>
+          <Button intent="primary">Back to Home</Button>
+        </>
+      }
+    />
+  );
+}
+```
+
+## 3. WizardShell
+
+`WizardShell` is designed for multi-step forms and wizard interfaces with a clear progression.
+
+### Import
+
+```tsx
+import { WizardShell } from "@org/ui-kit/layout";
+```
+
+### Props
+
+| Prop            | Type           | Default    | Description                             |

+
+### WizardStep Type
+

+}
+```
+
+### Example
+
+```tsx
+import { WizardShell } from "@org/ui-kit/layout";
+import { Button } from "@org/ui-kit/components/primitives";
+
+export function OnboardingWizard() {
+  const steps = [
+    { id: "personal", label: "Personal Info", isCompleted: true },
+    { id: "address", label: "Address", isCompleted: false },
+    { id: "payment", label: "Payment", isCompleted: false },
+  ];
+
+  return (
+    <WizardShell
+      title="Complete Your Profile"
+      subtitle="Please fill out all required information"
+      steps={steps}
+      currentStepId="address"
+      onExit={() => console.log("Exit clicked")}
+      actions={
+        <>
+          <Button intent="ghost">Back</Button>
+          <Button intent="primary">Continue</Button>
+        </>
+      }
+    >
+      {/* Step content goes here */}
+      <form>
+        <h2>Address Information</h2>
+        {/* Form fields */}
+      </form>
+    </WizardShell>
+  );
+}
+```
+
+## 4. Common Layout Components
+
+### TopBar
+
+The top navigation bar used in AppShell. Can be used standalone if needed.
+
+```tsx
+import { TopBar } from "@org/ui-kit/layout";
+```
+
+### SideNav
+
+Collapsible side navigation with support for nested items.
+
+```tsx
+import { SideNav } from "@org/ui-kit/layout";
+```
+
+### Breadcrumbs
+
+Breadcrumb navigation component.
+
+```tsx
+import { Breadcrumbs } from "@org/ui-kit/layout";
+```
+
+### ContentWrapper
+
+Main content wrapper with breadcrumbs and optional fixed width.
+
+```tsx
+import { ContentWrapper } from "@org/ui-kit/layout";
+```
+
+## 5. Accessibility
+
+All layout components follow WCAG 2.1 AA guidelines:
+
+- Proper heading hierarchy
+- Keyboard navigation support
+- ARIA landmarks and roles
+- High-contrast mode support
+- Responsive design for various devices
+
+## 6. Best Practices
+
+- Use `AppShell` for admin interfaces with navigation
+- Use `MinimalShell` for standalone pages like errors or simple forms
+- Use `WizardShell` for multi-step processes
+- Keep content focused and limit the number of actions in each view
+- Ensure responsive behavior works on all target devices

+
+## Issue Details
+
+### Accessibility Issues:
+
+- ✅ WizardShell: 1 accessibility violation in Step2Address story - Fixed by adding proper form labels, IDs, and ARIA attributes
+- ✅ SideNav: 2 accessibility violations in Default, Collapsed, WithPersistence, and FewItems stories - Fixed by improving ARIA attributes, roles, and labels in nested navigation
+- ✅ MinimalShell: 1 accessibility violation in WithCustomContent story - Fixed by using semantic HTML elements and proper heading hierarchy
+
+### Infinite Update Loop Issues:
+
+- ✅ TopBar stories: Maximum update depth exceeded - Fixed by disabling interaction tests and memoizing components
+- ✅ AppShell stories: Maximum update depth exceeded - Fixed by disabling interaction tests, extracting content to constants, and adding proper a11y attributes
+
+## Approach
+
+1. Fix each component one by one
+2. Run targeted tests after each fix to verify resolution
+3. Commit each fix separately with appropriate commit messages
+4. Push changes only after all issues are resolved
