-# Lit + Zustand Architecture
+# Lit-Only Architecture (No Build)
 
-A simple (but modern & scalable) no-build web application architecture using Lit web components with Zustand state management and IndexedDB persistence.
+A minimal, no-build web application using only Lit web components with local state management.
+
+> **Note:** This is the `lit-only` branch. For the full-featured version with Zustand state management and IndexedDB persistence, see the `main` branch.
 
 ## For TSX/React Developers
 
-If you're coming from React/TSX, here's how this architecture maps to familiar concepts:
+If you're coming from React/TSX, here's how this minimal architecture maps to familiar concepts:
 
 | React/TSX Pattern | This Architecture |
 |-------------------|-------------------|
-| `useState` / `useReducer` | Zustand vanilla store |
-| `useEffect` + state subscription | `StoreController` (ReactiveController) |
-| Context API | Global Zustand store |
-| `localStorage` / `sessionStorage` | IndexedDB via persist middleware |
+| `useState` | Lit's `static properties` with `state: true` |
+| Props drilling | Property passing via `.prop=${value}` |
+| Custom events | `CustomEvent` with `bubbles: true` |
 | JSX | Lit's `html` tagged template literals |
 | CSS-in-JS / CSS Modules | Lit's `css` tagged template literals |
-| React Router | Simple route state in store |
+| React Router | Simple route state in root component |
 | Build step (Vite/Webpack) | Import maps (no build!) |
 
 ### Key Differences
 
 1. **No Virtual DOM**: Lit uses native Web Components with efficient DOM updates
 2. **No Build Step**: Import maps let you use npm packages directly from CDN
-3. **Reactive Controllers**: Replace hooks - attach to component lifecycle
-4. **Tagged Templates**: Instead of JSX, use `html\`<div>...</div>\``
+3. **Local State Only**: Each component manages its own state, parent manages shared state
+4. **Event-Based Communication**: Child components emit events, parent handles them
+5. **Tagged Templates**: Instead of JSX, use `html\`<div>...</div>\``
 
 ## Architecture Overview
 
 * **Lit-based web components** - Standards-based, framework-agnostic UI
 * **No-build tooling** - Import maps only, no bundler required
-* **Zustand state management** - Lightweight, vanilla JS store
-* **IndexedDB persistence** - Automatic state persistence with idb-keyval
+* **Local state management** - Component properties and state
+* **Event-driven** - CustomEvents for child-to-parent communication

 ## Quick Start Example
 
-### 1. Define Store (like Redux/Zustand)
-
-```javascript
-// store/index.js
-import { createStore } from 'zustand/vanilla'
-import { persist } from 'zustand/middleware'
-
-export const store = createStore(
-  persist(
-    (set) => ({
-      count: 0,
-      increment: () => set(s => ({ count: s.count + 1 })),
-    }),
-    { name: 'my-store' }
-  )
-)
-```
-
-### 2. Create Component (like React component)
+### 1. Define a Component
 
 ```javascript
 // components/counter.js
 import { LitElement, html, css } from 'lit'
-import { StoreController } from '../controllers/store.js'
-import { store } from '../store/index.js'
 
 class Counter extends LitElement {
-  // Subscribe to store (like useSelector)
-  #count = new StoreController(this, store, s => s.count)
+  static properties = {
+    count: { type: Number, state: true }
+  }
+
+  constructor() {

+## Component Communication Patterns
+
+### Pattern 1: Shared State in Root
+
+```javascript
+class AppRoot extends LitElement {
+  static properties = {
+    items: { type: Array, state: true }
+  }
+
+  constructor() {
+    super()
+    this.items = []
+  }
+
+  addItem(item) {
+    this.items = [...this.items, item]
+  }
+
+  render() {
+    return html`
+      <child-component 
+        .items=${this.items}
+        @add=${(e) => this.addItem(e.detail.item)}
+      ></child-component>
+    `
+  }
+}
+```
+
+### Pattern 2: Local State in Component
+
+```javascript
+class MyComponent extends LitElement {
+  static properties = {
+    _draft: { type: String, state: true }
+  }
+
+  constructor() {
+    super()
+    this._draft = ''
+  }
+
+  render() {
+    return html`
+      <input 
+        .value=${this._draft}
+        @input=${e => this._draft = e.target.value}
+      />
+    `
+  }
+}
+```
+
 ## Benefits Over React/TSX
 
 ✅ **No build step** - Edit and refresh, instant feedback  
+✅ **Minimal dependencies** - Just Lit, nothing else  
 ✅ **Smaller bundle** - No framework runtime, just standards  
 ✅ **Better encapsulation** - Shadow DOM, scoped styles  
 ✅ **Framework agnostic** - Works anywhere, even in React apps  
 ✅ **Future-proof** - Built on web standards  
+✅ **Easy to learn** - Simple mental model, no complex state management
+
+## When to Use This vs. Full Stack
+
+### Use Lit-Only When:
+- Building small to medium apps
+- Don't need persistence
+- State is simple and hierarchical
+- Want maximum simplicity
+
+### Use Full Stack (main branch) When:
+- Need IndexedDB persistence
+- Complex state shared across many components
+- Need cross-tab synchronization
+- Want time-travel debugging
+- Building larger applications

-# Lit-Only Architecture (No Build)
+# zulip
 
-A minimal, no-build web application using only Lit web components with local state management.
+A minimal, no-build web app kit using only Lit-based web components via importmaps.
 
-> **Note:** This is the `lit-only` branch. For the full-featured version with Zustand state management and IndexedDB persistence, see the `main` branch.
-
-## For TSX/React Developers
-
-If you're coming from React/TSX, here's how this minimal architecture maps to familiar concepts:
-
-| React/TSX Pattern | This Architecture |
-|-------------------|-------------------|
-| `useState` | Lit's `static properties` with `state: true` |
-| Props drilling | Property passing via `.prop=${value}` |
-| Custom events | `CustomEvent` with `bubbles: true` |
-| JSX | Lit's `html` tagged template literals |
-| CSS-in-JS / CSS Modules | Lit's `css` tagged template literals |
-| React Router | Simple route state in root component |
-| Build step (Vite/Webpack) | Import maps (no build!) |
-
-### Key Differences
-
-1. **No Virtual DOM**: Lit uses native Web Components with efficient DOM updates
-2. **No Build Step**: Import maps let you use npm packages directly from CDN
-3. **Local State Only**: Each component manages its own state, parent manages shared state
-4. **Event-Based Communication**: Child components emit events, parent handles them
-5. **Tagged Templates**: Instead of JSX, use `html\`<div>...</div>\``
-
-## Architecture Overview
-
-* **Lit-based web components** - Standards-based, framework-agnostic UI
-* **No-build tooling** - Import maps only, no bundler required
-* **Local state management** - Component properties and state
-* **Event-driven** - CustomEvents for child-to-parent communication
-
-## Project Structure
-
-```
-components/
-  app-root.js       ← Root component with shared state
-  nav-bar.js        ← Navigation component
-  page-home.js      ← Home page component
-  page-items.js     ← Items page component
-index.html          ← Entry point with inline importmap
-README.md
-tasks.md
-```
-
-## Data Flow Pattern
-
-### Parent-to-Child (Props)
-
-```javascript
-// Parent passes data down
-html`<child-component .items=${this.items}></child-component>`
-
-// Child receives via properties
-static properties = {
-  items: { type: Array }
-}
-```
-
-### Child-to-Parent (Events)
-
-```javascript
-// Child emits event
-this.dispatchEvent(new CustomEvent('add-item', {
-  detail: { item: newItem },
-  bubbles: true,
-  composed: true
-}))
-
-// Parent listens
-html`<child-component @add-item=${(e) => this.handleAdd(e.detail.item)}></child-component>`
-```
-
-## State Management Pattern
-
-```mermaid
-graph TD
-    A[app-root] -->|.user, .items, .route| B[nav-bar]
-    A -->|.user, .items| C[page-home]
-    A -->|.items| D[page-items]
-    B -->|@navigate event| A
-    D -->|@add-item event| A
-    D -->|@remove-item event| A
-    
-    style A fill:#f9f,stroke:#333,stroke-width:2px
-    style B fill:#bbf,stroke:#333,stroke-width:2px
-    style C fill:#bfb,stroke:#333,stroke-width:2px
-    style D fill:#bfb,stroke:#333,stroke-width:2px

-## Component Communication Patterns
-
-### Pattern 1: Shared State in Root
-
-```javascript
 class AppRoot extends LitElement {
-  static properties = {
-    items: { type: Array, state: true }
-  }
-
-  constructor() {
-    super()
-    this.items = []
-  }
-
-  addItem(item) {
-    this.items = [...this.items, item]
-  }
-
+  ...
   render() {
-    return html`
-      <child-component 
-        .items=${this.items}
-        @add=${(e) => this.addItem(e.detail.item)}
-      ></child-component>
-    `
+    return html`<my-counter .count=${0}></my-counter>`;
   }
 }
 ```
 
-### Pattern 2: Local State in Component
+### 3. Define Data Flows
+
+#### Parent-to-Child (Props)
 
 ```javascript
-class MyComponent extends LitElement {
-  static properties = {
-    _draft: { type: String, state: true }
-  }
+// Parent passes data down
+html`<child-component .items=${this.items}></child-component>`
 
-  constructor() {
-    super()
-    this._draft = ''
-  }
-
-  render() {
-    return html`
-      <input 
-        .value=${this._draft}
-        @input=${e => this._draft = e.target.value}
-      />
-    `
-  }
+// Child receives via properties
+static properties = {
+  items: { type: Array }
 }
 ```
 
-## Benefits Over React/TSX
+#### Child-to-Parent (Events)
 
-✅ **No build step** - Edit and refresh, instant feedback  
-✅ **Minimal dependencies** - Just Lit, nothing else  
-✅ **Smaller bundle** - No framework runtime, just standards  
-✅ **Better encapsulation** - Shadow DOM, scoped styles  
-✅ **Framework agnostic** - Works anywhere, even in React apps  
-✅ **Future-proof** - Built on web standards  
-✅ **Easy to learn** - Simple mental model, no complex state management
+```javascript
+// Child emits event
+this.dispatchEvent(new CustomEvent('add-item', {
+  detail: { item: newItem },
+  bubbles: true,
+  composed: true
+}))
 
-## When to Use This vs. Full Stack
+// Parent listens
+html`<child-component @add-item=${(e) => this.handleAdd(e.detail.item)}></child-component>`
+```
 
-### Use Lit-Only When:
-- Building small to medium apps
-- Don't need persistence
-- State is simple and hierarchical
-- Want maximum simplicity
+## Benefits Over TSX
 
-### Use Full Stack (main branch) When:
-- Need IndexedDB persistence
-- Complex state shared across many components
-- Need cross-tab synchronization
-- Want time-travel debugging
-- Building larger applications
+1. **No build step** - Edit and refresh, instant feedback
