-### View Transitions
-
-The View Transitions API creates smooth animations between DOM state changes. When implementing view transitions:
-
-**Core Resources:**
-
-- **Utility wrapper**: `src/common/util/view-transition.ts` - `withViewTransition()` function with graceful fallback
-- **Real-world example**: `src/util/launch-screen.ts` - Launch screen fade pattern with browser support detection
-- **Animation keyframes**: `src/resources/theme/animations.globals.ts` - Global `fade-in`, `fade-out`, `scale` animations
-- **Animation duration**: `src/resources/theme/core.globals.ts` - `--ha-animation-duration-fast` (150ms), `--ha-animation-duration-normal` (250ms), `--ha-animation-duration-slow` (350ms) (all respect `prefers-reduced-motion`)
-
-**Implementation Guidelines:**
-
-1. Always use `withViewTransition()` wrapper for automatic fallback
-2. Keep transitions simple (subtle crossfades and fades work best)
-3. Use `--ha-animation-duration-*` CSS variables for consistent timing (`fast`, `normal`, `slow`)
-4. Assign unique `view-transition-name` to elements (must be unique at any given time)
-5. For Lit components: Override `performUpdate()` or use `::part()` for internal elements
-
-**Default Root Transition:**
-
-By default, `:root` receives `view-transition-name: root`, creating a full-page crossfade. Target with [`::view-transition-group(root)`](https://developer.mozilla.org/en-US/docs/Web/CSS/::view-transition-group) to customize the default page transition.
-
-**Important Constraints:**
-
-- Each `view-transition-name` must be unique at any given time
-- Only one view transition can run at a time
-- **Shadow DOM incompatibility**: View transitions operate at document level and do not work within Shadow DOM due to style isolation ([spec discussion](https://github.com/w3c/csswg-drafts/issues/10303)). For web components, set `view-transition-name` on the `:host` element or use document-level transitions
-
-**Specification & Documentation:**
-
-For browser support, API details, and current specifications, refer to these authoritative sources (note: check publication dates as specs evolve):
-
-- [MDN: View Transition API](https://developer.mozilla.org/en-US/docs/Web/API/View_Transition_API) - Comprehensive API reference

 **Dialog Implementation Requirements:**
 
-- Use `ha-dialog` component
 - Implement `HassDialog<T>` interface
-- Use `@state() private _open = false` to control dialog visibility
-- Set `_open = true` in `showDialog()`, `_open = false` in `closeDialog()`
+- Use `createCloseHeading()` for standard headers
+- Import `haStyleDialog` for consistent styling
 - Return `nothing` when no params (loading state)
-- Fire `dialog-closed` event in `_dialogClosed()` handler
-- Use `header-title` attribute for simple titles
-- Use `header-subtitle` attribute for simple subtitles
-- Use slots for custom content where the standard attributes are not enough
-- Use `ha-dialog-footer` with `primaryAction`/`secondaryAction` slots for footer content
-- Add `autofocus` to first focusable element (e.g., `<ha-form autofocus>`). The component may need to forward this attribute internally.
+- Fire `dialog-closed` event when closing
+- Add `dialogInitialFocus` for accessibility
 
-**Dialog Sizing:**
-
-- Use `width` attribute with predefined sizes: `"small"` (320px), `"medium"` (560px - default), `"large"` (720px), or `"full"`
-- Custom sizing is NOT recommended - use the standard width presets
-
-**Button Appearance Guidelines:**
-
-- **Primary action buttons**: Default appearance (no appearance attribute) or omit for standard styling
-- **Secondary action buttons**: Use `appearance="plain"` for cancel/dismiss actions
-- **Destructive actions**: Use `appearance="filled"` for delete/remove operations (combined with appropriate semantic styling)
-- **Button sizes**: Use `size="small"` (32px height) or default/medium (40px height)
-- Always place primary action in `slot="primaryAction"` and secondary in `slot="secondaryAction"` within `ha-dialog-footer`
