-## Quick Reference
-
-### Essential Commands
-
-```bash
-yarn lint          # ESLint + Prettier + TypeScript + Lit
-yarn format        # Auto-fix ESLint + Prettier
-yarn lint:types    # TypeScript compiler
-yarn test          # Vitest
-script/develop     # Development server
-```
-
-### Component Prefixes
-
-- `ha-` - Home Assistant components
-- `hui-` - Lovelace UI components
-- `dialog-` - Dialog components
-
-### Import Patterns
-
-```typescript
-import type { HomeAssistant } from "../types";
-import { fireEvent } from "../common/dom/fire_event";
-import { showAlertDialog } from "../dialogs/generic/show-alert-dialog";
-```
-
-## Core Architecture
-
-The Home Assistant frontend is a modern web application that:
-
-- Uses Web Components (custom elements) built with Lit framework
-- Is written entirely in TypeScript with strict type checking
-- Communicates with the backend via WebSocket API
-- Provides comprehensive theming and internationalization
-
-## Development Standards
-
-### Code Quality Requirements
-
-**Linting and Formatting (Enforced by Tools)**
-
-- ESLint config extends Airbnb, TypeScript strict, Lit, Web Components, Accessibility
-- Prettier with ES5 trailing commas enforced
-- No console statements (`no-console: "error"`) - use proper logging
-- Import organization: No unused imports, consistent type imports
-
-**Naming Conventions**
-
-- PascalCase for types and classes
-- camelCase for variables, methods
-- Private methods require leading underscore
-- Public methods forbid leading underscore
-
-### TypeScript Usage
-
-- **Always use strict TypeScript**: Enable all strict flags, avoid `any` types
-- **Proper type imports**: Use `import type` for type-only imports
-- **Define interfaces**: Create proper interfaces for data structures
-- **Type component properties**: All Lit properties must be properly typed
-- **No unused variables**: Prefix with `_` if intentionally unused
-- **Consistent imports**: Use `@typescript-eslint/consistent-type-imports`
-
-```typescript
-// Good
-import type { HomeAssistant } from "../types";
-
-interface EntityConfig {
-  entity: string;
-  name?: string;
-}
-
-@property({ type: Object })
-hass!: HomeAssistant;
-
-// Bad
-@property()
-hass: any;
-```
-
-### Web Components with Lit
-
-- **Use Lit 3.x patterns**: Follow modern Lit practices
-- **Extend appropriate base classes**: Use `LitElement`, `SubscribeMixin`, or other mixins as needed
-- **Define custom element names**: Use `ha-` prefix for components
-
-```typescript
-@customElement("ha-my-component")
-export class HaMyComponent extends LitElement {
-  @property({ attribute: false })
-  hass!: HomeAssistant;
-
-  @state()
-  private _config?: MyComponentConfig;
-
-  static get styles() {
-    return css`
-      :host {
-        display: block;
-      }
-    `;
-  }
-
-  render() {
-    return html`<div>Content</div>`;
-  }
-}
-```
-
-### Component Guidelines
-
-- **Use composition**: Prefer composition over inheritance
-- **Lazy load panels**: Heavy panels should be dynamically imported
-- **Optimize renders**: Use `@state()` for internal state, `@property()` for public API
-- **Handle loading states**: Always show appropriate loading indicators
-- **Support themes**: Use CSS custom properties from theme
-
-### Data Management
-
-- **Use WebSocket API**: All backend communication via home-assistant-js-websocket
-- **Cache appropriately**: Use collections and caching for frequently accessed data
-- **Handle errors gracefully**: All API calls should have error handling
-- **Update real-time**: Subscribe to state changes for live updates
-
-```typescript
-// Good
-try {
-  const result = await fetchEntityRegistry(this.hass.connection);
-  this._processResult(result);
-} catch (err) {
-  showAlertDialog(this, {
-    text: `Failed to load: ${err.message}`,
-  });
-}
-```
-
-### Styling Guidelines
-
-- **Use CSS custom properties**: Leverage the theme system
-- **Mobile-first responsive**: Design for mobile, enhance for desktop
-- **Follow Material Design**: Use Material Web Components where appropriate
-- **Support RTL**: Ensure all layouts work in RTL languages
-
-```typescript
-static get styles() {
-  return css`
-    :host {
-      --spacing: 16px;
-      padding: var(--spacing);
-      color: var(--primary-text-color);
-      background-color: var(--card-background-color);
-    }
-
-    @media (max-width: 600px) {
-      :host {
-        --spacing: 8px;
-      }
-    }
-  `;
-}
-```
-
-### Performance Best Practices
-
-- **Code split**: Split code at the panel/dialog level
-- **Lazy load**: Use dynamic imports for heavy components
-- **Optimize bundle**: Keep initial bundle size minimal
-- **Use virtual scrolling**: For long lists, implement virtual scrolling
-- **Memoize computations**: Cache expensive calculations
-
-### Testing Requirements
-
-- **Write tests**: Add tests for data processing and utilities
-- **Test with Vitest**: Use the established test framework
-- **Mock appropriately**: Mock WebSocket connections and API calls
-- **Test accessibility**: Ensure components are accessible
-
-## Component Library
-
-### Dialog Components
-
-**Available Dialog Types:**
-
-- `ha-md-dialog` - Preferred for new code (Material Design 3)
-- `ha-dialog` - Legacy component still widely used
-
-**Opening Dialogs (Fire Event Pattern - Recommended):**
-
-```typescript
-fireEvent(this, "show-dialog", {
-  dialogTag: "dialog-example",
-  dialogImport: () => import("./dialog-example"),
-  dialogParams: { title: "Example", data: someData },
-});
-```
-
-**Dialog Implementation Requirements:**
-
-- Implement `HassDialog<T>` interface
-- Use `createCloseHeading()` for standard headers
-- Import `haStyleDialog` for consistent styling
-- Return `nothing` when no params (loading state)
-- Fire `dialog-closed` event when closing
-- Add `dialogInitialFocus` for accessibility
-
-````
-
-### Form Component (ha-form)
-- Schema-driven using `HaFormSchema[]`
-- Supports entity, device, area, target, number, boolean, time, action, text, object, select, icon, media, location selectors
-- Built-in validation with error display
-- Use `dialogInitialFocus` in dialogs
-- Use `computeLabel`, `computeError`, `computeHelper` for translations
-
-```typescript
-<ha-form
-  .hass=${this.hass}
-  .data=${this._data}
-  .schema=${this._schema}
-  .error=${this._errors}
-  .computeLabel=${(schema) => this.hass.localize(`ui.panel.${schema.name}`)}
-  @value-changed=${this._valueChanged}
-></ha-form>
-````
-
-### Alert Component (ha-alert)
-
-- Types: `error`, `warning`, `info`, `success`
-- Properties: `title`, `alert-type`, `dismissable`, `icon`, `action`, `rtl`
-- Content announced by screen readers when dynamically displayed
-
-```html
-<ha-alert alert-type="error">Error message</ha-alert>
-<ha-alert alert-type="warning" title="Warning">Description</ha-alert>
-<ha-alert alert-type="success" dismissable>Success message</ha-alert>
-```
-
-## Common Patterns
-
-### Creating a Panel
-
-```typescript
-@customElement("ha-panel-myfeature")
-export class HaPanelMyFeature extends SubscribeMixin(LitElement) {
-  @property({ attribute: false })
-  hass!: HomeAssistant;
-
-  @property({ type: Boolean, reflect: true })
-  narrow!: boolean;
-
-  @property()
-  route!: Route;
-
-  hassSubscribe() {
-    return [
-      subscribeEntityRegistry(this.hass.connection, (entities) => {
-        this._entities = entities;
-      }),
-    ];
-  }
-}
-```
-
-### Creating a Dialog
-
-```typescript
-@customElement("dialog-my-feature")
-export class DialogMyFeature
-  extends LitElement
-  implements HassDialog<MyDialogParams>
-{
-  @property({ attribute: false })
-  hass!: HomeAssistant;
-
-  @state()
-  private _params?: MyDialogParams;
-
-  public async showDialog(params: MyDialogParams): Promise<void> {
-    this._params = params;
-  }
-
-  public closeDialog(): void {
-    this._params = undefined;
-    fireEvent(this, "dialog-closed", { dialog: this.localName });
-  }
-
-  protected render() {
-    if (!this._params) {
-      return nothing;
-    }
-
-    return html`
-      <ha-dialog
-        open
-        @closed=${this.closeDialog}
-        .heading=${createCloseHeading(this.hass, this._params.title)}
-      >
-        <!-- Dialog content -->
-        <ha-button @click=${this.closeDialog} slot="secondaryAction">
-          ${this.hass.localize("ui.common.cancel")}
-        </ha-button>
-        <ha-button @click=${this._submit} slot="primaryAction">
-          ${this.hass.localize("ui.common.save")}
-        </ha-button>
-      </ha-dialog>
-    `;
-  }
-
-  static styles = [haStyleDialog, css``];
-}
-```
-
-### Dialog Design Guidelines
-
-- Max width: 560px (Alert/confirmation: 320px fixed width)
-- Close X-icon on top left (all screen sizes)
-- Submit button grouped with cancel at bottom right
-- Keep button labels short: "Save", "Delete", "Enable"
-- Destructive actions use red warning button
-- Always use a title (best practice)
-- Strive for minimalism
-
-#### Creating a Lovelace Card
-
-**Purpose**: Cards allow users to tell different stories about their house (based on gallery)
-
-```typescript
-@customElement("hui-my-card")
-export class HuiMyCard extends LitElement implements LovelaceCard {
-  @property({ attribute: false })
-  hass!: HomeAssistant;
-
-  @state()
-  private _config?: MyCardConfig;
-
-  public setConfig(config: MyCardConfig): void {
-    if (!config.entity) {
-      throw new Error("Entity required");
-    }
-    this._config = config;
-  }
-
-  public getCardSize(): number {
-    return 3; // Height in grid units
-  }
-
-  // Optional: Editor for card configuration
-  public static getConfigElement(): LovelaceCardEditor {
-    return document.createElement("hui-my-card-editor");
-  }
-
-  // Optional: Stub config for card picker
-  public static getStubConfig(): object {
-    return { entity: "" };
-  }
-}
-```
-
-**Card Guidelines:**
-
-- Cards are highly customizable for different households
-- Implement `LovelaceCard` interface with `setConfig()` and `getCardSize()`
-- Use proper error handling in `setConfig()`
-- Consider all possible states (loading, error, unavailable)
-- Support different entity types and states
-- Follow responsive design principles
-- Add configuration editor when needed
-
-### Internationalization
-
-- **Use localize**: Always use the localization system
-- **Add translation keys**: Add keys to src/translations/en.json
-- **Support placeholders**: Use proper placeholder syntax
-
-```typescript
-this.hass.localize("ui.panel.config.updates.update_available", {
-  count: 5,
-});
-```
-
-### Accessibility
-
-- **ARIA labels**: Add appropriate ARIA labels
-- **Keyboard navigation**: Ensure all interactions work with keyboard
-- **Screen reader support**: Test with screen readers
-- **Color contrast**: Meet WCAG AA standards
-
-## Development Workflow
-
-### Setup and Commands
-
-1. **Setup**: `script/setup` - Install dependencies
-2. **Develop**: `script/develop` - Development server
-3. **Lint**: `yarn lint` - Run all linting before committing
-4. **Test**: `yarn test` - Add and run tests
-5. **Build**: `script/build_frontend` - Test production build
-
-### Common Pitfalls to Avoid
-
-- Don't use `querySelector` - Use refs or component properties
-- Don't manipulate DOM directly - Let Lit handle rendering
-- Don't use global styles - Scope styles to components
-- Don't block the main thread - Use web workers for heavy computation
-- Don't ignore TypeScript errors - Fix all type issues
-
-### Security Best Practices
-
-- Sanitize HTML - Never use `unsafeHTML` with user content
-- Validate inputs - Always validate user inputs
-- Use HTTPS - All external resources must use HTTPS
-- CSP compliance - Ensure code works with Content Security Policy
-
-### Text and Copy Guidelines
-
-#### Terminology Standards
-
-**Delete vs Remove** (Based on gallery/src/pages/Text/remove-delete-add-create.markdown)
-
-- **Use "Remove"** for actions that can be restored or reapplied:
-  - Removing a user's permission
-  - Removing a user from a group
-  - Removing links between items
-  - Removing a widget from dashboard
-  - Removing an item from a cart
-- **Use "Delete"** for permanent, non-recoverable actions:
-  - Deleting a field
-  - Deleting a value in a field
-  - Deleting a task
-  - Deleting a group
-  - Deleting a permission
-  - Deleting a calendar event
-
-**Create vs Add** (Create pairs with Delete, Add pairs with Remove)
-
-- **Use "Add"** for already-existing items:
-  - Adding a permission to a user
-  - Adding a user to a group
-  - Adding links between items
-  - Adding a widget to dashboard
-  - Adding an item to a cart
-- **Use "Create"** for something made from scratch:
-  - Creating a new field
-  - Creating a new task
-  - Creating a new group
-  - Creating a new permission
-  - Creating a new calendar event
-
-#### Writing Style (Consistent with Home Assistant Documentation)
-
-- **Use American English**: Standard spelling and terminology
-- **Friendly, informational tone**: Be inspiring, personal, comforting, engaging
-- **Address users directly**: Use "you" and "your"
-- **Be inclusive**: Objective, non-discriminatory language
-- **Be concise**: Use clear, direct language
-- **Be consistent**: Follow established terminology patterns
-- **Use active voice**: "Delete the automation" not "The automation should be deleted"
-- **Avoid jargon**: Use terms familiar to home automation users
-
-#### Language Standards
-
-- **Always use "Home Assistant"** in full, never "HA" or "HASS"
-- **Avoid abbreviations**: Spell out terms when possible
-- **Use sentence case everywhere**: Titles, headings, buttons, labels, UI elements
-  - ✅ "Create new automation"
-  - ❌ "Create New Automation"
-  - ✅ "Device settings"
-  - ❌ "Device Settings"
-- **Oxford comma**: Use in lists (item 1, item 2, and item 3)
-- **Replace Latin terms**: Use "like" instead of "e.g.", "for example" instead of "i.e."
-- **Avoid CAPS for emphasis**: Use bold or italics instead
-- **Write for all skill levels**: Both technical and non-technical users
-
-#### Key Terminology
-
-- **"add-on"** (hyphenated, not "addon")
-- **"integration"** (preferred over "component")
-- **Technical terms**: Use lowercase (automation, entity, device, service)
-
-#### Translation Considerations
-
-- **Add translation keys**: All user-facing text must be translatable
-- **Use placeholders**: Support dynamic content in translations
-- **Keep context**: Provide enough context for translators
-
-```typescript
-// Good
-this.hass.localize("ui.panel.config.automation.delete_confirm", {
-  name: automation.alias,
-});
-
-// Bad - hardcoded text
-("Are you sure you want to delete this automation?");
-```
-
-### Common Review Issues (From PR Analysis)
-
-#### User Experience and Accessibility
-
-- **Form validation**: Always provide proper field labels and validation feedback
-- **Form accessibility**: Prevent password managers from incorrectly identifying fields
-- **Loading states**: Show clear progress indicators during async operations
-- **Error handling**: Display meaningful error messages when operations fail
-- **Mobile responsiveness**: Ensure components work well on small screens
-- **Hit targets**: Make clickable areas large enough for touch interaction
-- **Visual feedback**: Provide clear indication of interactive states
-
-#### Dialog and Modal Patterns
-
-- **Dialog width constraints**: Respect minimum and maximum width requirements
-- **Interview progress**: Show clear progress for multi-step operations
-- **State persistence**: Handle dialog state properly during background operations
-- **Cancel behavior**: Ensure cancel/close buttons work consistently
-- **Form prefilling**: Use smart defaults but allow user override
-
-#### Component Design Patterns
-
-- **Terminology consistency**: Use "Join"/"Apply" instead of "Group" when appropriate
-- **Visual hierarchy**: Ensure proper font sizes and spacing ratios
-- **Grid alignment**: Components should align to the design grid system
-- **Badge placement**: Position badges and indicators consistently
-- **Color theming**: Respect theme variables and design system colors
-
-#### Code Quality Issues
-
-- **Null checking**: Always check if entities exist before accessing properties
-- **TypeScript safety**: Handle potentially undefined array/object access
-- **Import organization**: Remove unused imports and use proper type imports
-- **Event handling**: Properly subscribe and unsubscribe from events
-- **Memory leaks**: Clean up subscriptions and event listeners
-
-#### Configuration and Props
-
-- **Optional parameters**: Make configuration fields optional when sensible
-- **Smart defaults**: Provide reasonable default values
-- **Future extensibility**: Design APIs that can be extended later
-- **Validation**: Validate configuration before applying changes
-
