 ## Theme And Layout Basics

 - Use Home Assistant CSS custom properties instead of hardcoded colors.
+- CSS in the static HTML templates under `src/html/` must give custom properties a fallback value (for example `var(--ha-space-4, 16px)`), because the global tokens only exist once the JS-appended global stylesheet from `append-ha-style` has loaded.
 - Use `--ha-space-*` spacing tokens instead of hardcoded spacing where possible.
 - Keep components mobile-first and enhance for desktop.
 - Keep layouts RTL-safe. Prefer logical properties when they fit.

It can be accessed via a web-based user interface, via apps for Android and iOS, or using voice commands via a supported virtual assistant like Google Home and Amazon Alexa.

 IoT devices and services are supported by modular support for controlling proprietary ecosystems if they provide public access via an Open API for third-party integrations and protocols like Bluetooth, MQTT, Zigbee, and Z-Wave, After the Home Assistant software application is installed as a computer appliance it will act as a central control system for home automation. Information from all entities it sees can be used and controlled from within scripts trigger automations using scheduling and "blueprint" subroutines, e.g. for controlling lighting, climate, entertainment systems, and appliances.

 The project was started as a Python application by Paulus Schoutsen in September 2013 and first published publicly on GitHub in November 2013. In July 2017, a managed operating system called Hass.io was initially introduced to make it easier use to use Home Assistant on single-board computers like the Raspberry Pi series. Its bundled "supervisor" management system allowed users to manage, backup, and update the local installation and introduced the option to extend the functionality of the software with add-ons.

+Home Assistant Components (`hac-*`): framework-agnostic web components built
+with [Lit](https://lit.dev).
+
+> Work in progress, not published yet.
+
+## Registration
+
+Every element is imported on its own, in one of two ways:
+
+| Import                                        | Registers in         | For                                                         |
+| --------------------------------------------- | -------------------- | ----------------------------------------------------------- |
+| `@home-assistant/components/<element>`        | Global registry      | Home Assistant itself                                       |
+| `@home-assistant/components/<element>/scoped` | Your scoped registry | Custom cards and other code that runs inside Home Assistant |
+
+`<element>` is the tag name without the `hac-` prefix, like `card` for
+`hac-card`.
+
+Both use the copy bundled with your code. A scoped copy is isolated from the
+one Home Assistant registers globally, so a custom card keeps the version it
+was built with.
+
+Global registration skips tag names that are already registered, so the first
+registration wins and nothing throws.
+
+### Global
+
+```ts
+import "@home-assistant/components/card";
+```
+
+### Scoped
+
+Pass the component's elements to `ScopedElementsMixin` for Lit, or to
+`createScopedElementRegistry` for plain custom elements. Forgetting the
+elements is a TypeScript error, and a runtime error in plain JavaScript.
+
+Lit:
+
+```ts
+import { LitElement, html } from "lit";
+import { ScopedElementsMixin } from "@home-assistant/components/scoped";
+import { hacCard } from "@home-assistant/components/card/scoped";
+
+class MyCard extends ScopedElementsMixin(LitElement, [hacCard]) {
+  render() {
+    return html`<hac-card>…</hac-card>`;
+  }
+}
+```
+
+Plain custom elements:
+
+```js
+import {
+  attachScopedShadow,
+  createScopedElement,
+  createScopedElementRegistry,
+} from "@home-assistant/components/scoped";
+import { hacCard } from "@home-assistant/components/card/scoped";
+
+// Create the registry once, outside the class: all instances of the card share it
+const registry = createScopedElementRegistry([hacCard]);
+
+class MyCard extends HTMLElement {
+  constructor() {
+    super();
+    const root = attachScopedShadow(this, { mode: "open" }, registry);
+    root.innerHTML = "<hac-card>…</hac-card>";
+    // or: root.append(createScopedElement(root, "hac-card"));
+  }
+}
+```
+
+`innerHTML`, `insertAdjacentHTML` and `createScopedElement` use the scoped
+registry. `document.createElement` uses the global one, so avoid it for
+scoped elements.
+
+Scoped registries need native support (Chrome 146+, Safari 26) or
+`@webcomponents/scoped-custom-element-registry`, which Home Assistant loads.
+Without either, elements are registered globally instead, and an already
+registered tag name keeps its existing class.
+
+Only elements rendered inside the shadow root use the scoped registry. Light
+DOM content, such as slotted elements, uses the registry of the tree it is
+written in.
+
+`lit` is a peer dependency.
+
+### TypeScript
+
+Each element's entry points declare its tag in `HTMLElementTagNameMap`, so
+`document.querySelector("hac-card")` and templates are typed once the element
+is imported. For the class itself, import its type from the `scoped` entry
+point; `import type` loads nothing at runtime:
+
+```ts
+import type { HacCard } from "@home-assistant/components/card/scoped";
+```
+
+The package has no root entry point: each element and the scoped helpers
+(`@home-assistant/components/scoped`) have their own.
+
+## Theming
+
+Each component exposes its own `--hac-*` custom properties, documented in its
+source, which take precedence. Next come the theme variables of the existing
+Home Assistant element it replaces, so current themes keep working: `hac-card`
+reads the variables of `ha-card` (`--ha-card-background`,
+`--card-background-color`, `--ha-card-border-radius`, …). Last come the
+semantic color tokens (`--ha-color-*`, like `--ha-color-surface-default`) and
+their light values, so the components also render outside Home Assistant.
+
+The legacy theme variables are a temporary bridge for this experiment, not the
+target design. Home Assistant always defines some of them, like
+`--card-background-color`, so inside Home Assistant they currently win over
+the semantic tokens. Once themes move to the semantic tokens, the legacy
+variables will be removed from the fallbacks.
+
+## Structure
+
+Each element has its own directory, named like its import path:
+
+```
+src/components/card/   <hac-card>  -> @home-assistant/components/card
+  hac-card.ts          class, does not register itself
+  info.ts              tag name and version
+  global.ts            registers globally
+  scoped.ts            element for a scoped registry  -> …/card/scoped
+```
+
+Shared code lives in `src/utils/`: `registration/` for defining elements
+(global and scoped) and `element/` for helpers that components use
+themselves, like slot checks.
+
+Every element has its own version in `info.ts`.
+
+Entry points are mapped with subpath patterns in `package.json`, so a new
+element directory needs no `package.json` change. Only `global.ts` files have
+side effects, which `sideEffects` relies on for tree shaking.
+
+## Development
+
+```bash
+pnpm --filter @home-assistant/components build   # ESM, type declarations and custom-elements.json to dist/
+pnpm --filter @home-assistant/components dev     # rebuild on change
+```
+
+Inside this repository the app uses the sources directly through
+the `ha-source` export condition, so no build is needed during development.
+The package is built with [Rslib](https://rslib.rs) in bundleless mode: every
+source file becomes its own ES module. The build then generates a
+[custom elements manifest](https://custom-elements-manifest.open-wc.org) from
+the JSDoc of each element, so document new slots, parts, CSS properties and
+events there.
