 ## Core Architecture
@@ -53,64 +52,13 @@ The Home Assistant frontend is a modern web application that:
 - Communicates with the backend via WebSocket API
 - Provides comprehensive theming and internationalization

-## State Access: Contexts Instead of `hass`
-
-Every component used to take the whole `hass: HomeAssistant` object — a god-object that re-renders on any unrelated `hass` change, forces tests to mock everything, and hides what a component actually reads. We're moving leaf components to **fine-grained [Lit context](https://lit.dev/docs/data/context/)**: consume only the slice you need and re-render only when it changes.
-
-For new code, consume the matching context instead of adding a `hass` property. `hass` stays for container components that own it and feed the providers; the canonical migration is [`hui-button-card.ts`](src/panels/lovelace/cards/hui-button-card.ts). Infrastructure: contexts in [`src/data/context/index.ts`](src/data/context/index.ts), the `consume…` helpers in [`src/common/decorators/consume-context-entry.ts`](src/common/decorators/consume-context-entry.ts), and `@transform` in [`src/common/decorators/transform.ts`](src/common/decorators/transform.ts). Providers are wired automatically by `contextMixin` on `HassBaseEl` — you only consume.
-
-### Contexts
-
-Consume the narrowest context that covers your reads:
-
-| Context                                                                 | Replaces                                                                                  |

-| `entitiesContext` / `devicesContext` / `areasContext` / `floorsContext` | `hass.entities` / `.devices` / `.areas` / `.floors` (or `registriesContext` for all four) |
-| `servicesContext`                                                       | `hass.services`                                                                           |
-| `internationalizationContext`                                           | `hass.localize`, `hass.locale`, `hass.language`                                           |
-| `formattersContext`                                                     | `hass.formatEntityName`, `hass.formatEntityState`, `hass.formatEntityAttributeName`, …    |
-| `configContext`                                                         | `hass.config`, `hass.user`, `hass.auth`, `hass.userData`                                  |
-| `connectionContext`                                                     | `hass.connection`, `hass.connected`, `hass.hassUrl`                                       |

-
-Lazy contexts (subscribe on first consumer, tear down after the last): `labelsContext`, `fullEntitiesContext`, `configEntriesContext`, `manifestsContext`. The single-field contexts (`localizeContext`, `themesContext`, `userContext`, …) are **deprecated** — use the grouped ones above.
-
-### Consuming
-
-Use the `consume…` helpers for entity-scoped and `localize` reads. `entityIdPath` is resolved against `this`, so these watch `this._config.entity`:
-
-```ts
-@state() @consumeEntityState({ entityIdPath: ["_config", "entity"] })
-private _stateObj?: HassEntity; // consumeEntityStates(...) for a record of several
-
-@state() @consumeEntityRegistryEntry({ entityIdPath: ["_config", "entity"] })
-private _entity?: EntityRegistryDisplayEntry;
-
-@state() @consumeLocalize()
-private _localize!: LocalizeFunc;
-```
-
-For any other single field, pair `@consume` with `@transform`:
-
-```ts
-@state()
-@consume({ context: uiContext, subscribe: true })
-@transform<HomeAssistantUI, Themes>({ transformer: ({ themes }) => themes })
-private _themes!: Themes;
-```
-
-`@transform`'s `watch` option re-runs the transformer when a host prop changes — needed when an entity id is computed, since `consumeEntityState` only watches the first path segment. To consume a whole group untransformed, drop `@transform` and type it `ContextType<typeof statesContext>`.

-# Gallery Agent Instructions
-
-This file applies to all files under `gallery/`. Follow the root `AGENTS.md` for repository-wide Home Assistant frontend, TypeScript, Lit, accessibility, and copy standards. This file adds gallery-specific structure, page, demo, and verification guidance.
-
-## Quick Reference
-
-Run commands from the repository root unless noted otherwise:
-
-```bash
-gallery/script/develop_gallery  # Start the gallery development server
-gallery/script/build_gallery    # Build the static gallery
-yarn lint                       # ESLint, Prettier, TypeScript, and Lit checks
-yarn lint:types                 # TypeScript compiler, without file arguments
-```
-
-Never run `yarn lint:types` or `tsc` with file arguments. See the root `AGENTS.md` for the generated `.js` file risk.
-
-## Purpose
-
-The gallery is a developer and designer reference for Home Assistant frontend UI patterns. It documents component APIs, shows realistic Lovelace and more-info states, captures brand and copy guidance, and provides reproducible demos that are safe to inspect outside a running Home Assistant instance.
-
- Prefer demonstrating real production components from `src/` instead of creating gallery-only replacements.
- Keep fake state, sample data, and demo-only helpers inside `gallery/`.
- Do not move gallery stubs or demo data into production code unless a production feature explicitly needs them.
- Do not hand-edit generated output under `gallery/build/` or `gallery/dist/`.
-
-## Structure
-
- `sidebar.js`: Defines gallery sections, headers, and explicit page ordering.
- `script/develop_gallery`: Wrapper for the `develop-gallery` gulp task.
- `script/build_gallery`: Wrapper for the `build-gallery` gulp task.
- `src/entrypoint.js`: Creates the `<ha-gallery>` shell.
- `src/ha-gallery.ts`: Renders the drawer, page routing, markdown descriptions, demos, edit links, and RTL toggle.
- `src/html/index.html.template`: HTML template used by the gallery build.
- `src/pages/<category>/<page>.markdown`: Optional page description and frontmatter.
- `src/pages/<category>/<page>.ts`: Optional live demo module for the same page id.
- `src/components/`: Gallery-only demo wrappers like `demo-card`, `demo-cards`, `demo-more-info`, and `page-description`.
- `src/data/`: Fake `hass`, demo states, mock traces, and reusable sample data.
- `public/`: Static assets copied into the gallery output.
-
-## Page Model
-
-Gallery pages are generated by `gather-gallery-pages` in `build-scripts/gulp/gallery.js`.
-
- A page id is the path under `src/pages/` without the extension, like `components/ha-button`.
- A `.markdown` file and a `.ts` file with the same page id become one gallery page.
- A page may have only markdown, only a TypeScript demo, or both.
- Markdown can contain YAML frontmatter with `title` and optional `subtitle`.
- Markdown that contains only frontmatter contributes metadata without rendering a description block.
- TypeScript demo modules are dynamically imported for side effects when the page is opened.
- A demo module must define a custom element named `demo-${category}-${page}` with slashes replaced by hyphens, like `demo-components-ha-button` for `components/ha-button`.
- `ha-gallery.ts` renders that element with `dynamicElement()` based on the current page id.
-
-## Sidebar
-
-Use `sidebar.js` when a page needs a visible section, section header, or deterministic ordering.
-
- `category` must match the first directory name under `src/pages/`.
- `header` is the section label shown in the drawer.
- `pages` is optional. When present, listed pages keep that exact order.
- Pages in a category that are not listed are appended alphabetically after the listed pages.
- New categories without a sidebar entry are appended by the generator with their category name as the header.
- If a listed page does not exist, the generator logs an error during `gather-gallery-pages`.
-
-## Markdown Pages
-
-Use markdown pages for explanations, design guidance, API notes, and copy standards.
-
- Start with frontmatter when the page needs a title or subtitle.
- Use sentence case for titles, headings, labels, and UI copy.
- Put the live example before the reference API when that makes the page easier to scan.
- Use fenced code blocks with a language tag for copyable examples.
- Keep examples short and focused on the behavior being documented.
- Prefer real component names and attributes over prose-only descriptions.
- Use Home Assistant terminology from the root `AGENTS.md`.
- For remove/delete and add/create wording, follow `src/pages/misc/remove-delete-add-create.markdown`.
-
-Gallery markdown is documentation content and is not localized with `localize`. If demo code creates production UI strings, keep those strings aligned with the root localization and copy guidance.
-
-## Demo Components
-
-Use TypeScript demo pages for interactive or stateful examples.
-
- Import production components from `../../../src/...` or the correct relative path from the demo file.
- Import reusable gallery helpers from `gallery/src/components/` when they already model the pattern.
- Use `demo-card` and `demo-cards` for Lovelace card examples that render YAML card configs.
- Use `demo-more-info` and `demo-more-infos` for more-info dialog examples.
- Use shared mock data from `src/data/` instead of repeating large fake state objects inline.
- Show meaningful states, such as loading, unavailable, empty, error, active, inactive, and disabled when relevant.
- Check responsive behavior and the gallery RTL toggle when layout or direction-sensitive UI changes.
- Keep unavoidable casts or loose demo parsing local to the demo helper or demo page.
-
-The gallery ESLint config allows `console` for gallery diagnostics. Do not copy that exception into production frontend code.
-
-## Content Standards
-
-The root copy standards still apply: use American English, sentence case, active voice, inclusive language, direct user-focused wording, and consistent Home Assistant terminology.
-
- Use `Home Assistant` in full, not `HA` or `HASS`.
- Use `integration` instead of `component` for product concepts.
- Use `Remove` for reversible disassociation and `Delete` for permanent deletion.
- Use `Add` for existing items and `Create` for something made from scratch.
- Avoid Latin abbreviations like `e.g.` and `i.e.` in prose.
- Avoid stitching sentence fragments together in production UI examples.
-
-## Verification
-
- For markdown, sidebar, and page-generation changes, run `gallery/script/build_gallery`.
- For TypeScript demo or gallery shell changes, run the smallest relevant check plus `yarn lint` when practical.
- For type checking, run `yarn lint:types` without file arguments.
- For visual changes, run `gallery/script/develop_gallery` and check the affected page on desktop, narrow viewport, and RTL when relevant.
- If verification is skipped, state which command was skipped and why.

-# Brand Personality
-
-These five traits describe who Home Assistant is, not how it speaks. Tone of voice – the playfulness, the informality, the warmth, etc – should flow naturally from these, and will help guide writers on how to bring the brand personality to life.
-
-The first four traits are relational: they describe how Home Assistant behaves toward its users.
-_Welcoming_ is about how we receive them.\
-_Candid_ is about how we communicate with them.\
-_Supportive_ is about how we help them.\
-_Generous_ is about how/what we give to them.\
-If any of these feel similar, it’s because they’re all expressions of the same underlying character, just in different moments of the user relationship.
-
-_Independent_ is different. It’s foundational: it describes who Home Assistant is at its core.\
-And it’s because of that independence that the other four traits feel genuine rather than performed. A corporate brand can try to be welcoming, candid, supportive, and generous,
-but without independence, those traits will always be managed and moderated.
-
-## Welcoming
-
-**Warm and open, kind, friendly, approachable, accommodating**\
-_But not: people pleasing, appeasing, sycophantic, ingratiating_\
-Home Assistant feels like a knowledgeable friend, not a product. We meet you at your own level, never talk down to you, and make you feel valued regardless of your technical ability. This isn’t performative, it’s expressed naturally in the small things: how errors are explained, documentation is written, and how the community talks to newcomers.
-
-## Candid
-
-**Direct, honest, transparent, unpretentious**\
-_But not: unfriendly, rude, blunt, unempathetic_\
-Home Assistant says what it means. We don’t hide complexity behind false simplicity, fall back on marketing fluff, or pretend limitations don’t exist. We respect users enough to be straight with them: about what Home Assistant can do, what it can't, and why it works the way it does. This is what builds real trust with users.
-
-## Supportive
-
-**Helpful, guiding, encouraging, empathetic, genuine**\
-_But not: directive, hollow, condescending, over-bearing_\
-Home Assistant always has your back. Whether you’re just starting out or deep into a complex setup, we steer you forward without taking over. Our support is genuine: practical, patient, and there when it’s needed most. Because Home Assistant wants every user to succeed in building a smart home with privacy, choice, and sustainability at its heart.
-
-## Generous
-
-**Empowering, trusting, giving, sharing**\
-_But not: overwhelming, indiscriminate, patronizing, controlling_\
-Home Assistant gives you everything you need today, and as your setup evolves. There are no strings attached: no artificial limits, features locked behind tiers, or deceptive patterns designed to tie you to a closed platform. We trust users with control, access, and transparency. This generosity is reciprocal: the time, knowledge, and care our community gives freely is what keeps Home Assistant thriving and truly open.
-
-## Independent
-
-**Principled, liberated, confident, imperfect**\
-_But not: conceited, obstinate, erratic, insular_\
-Home Assistant doesn’t feel the need to behave like an established tech brand or follow corporate rules. With no shareholders or VCs to answer to, we can say what we think, do things our own way, and not take ourselves too seriously. This freedom of spirit comes from the confidence of knowing our own values, and that our community shares them.

 - The close X-icon is on the top left, on all screen sizes. Except for alert and confirmation dialogs, they only have buttons and no X-icon. This is different compared to the Material guidelines.
- Dialogs can't be closed with ESC or clicked outside of the dialog when there is a form that the user **has made changes to**. Instead it will animate "no" by a little shake.
+- Dialogs can't be closed with ESC or clicked outside of the dialog when there is a form that the user needs to fill out. Instead it will animate "no" by a little shake.
 - Extra icon buttons are on the top right, for example help, settings and expand dialog. More than 2 icon buttons, they will be in an overflow menu.
 - The submit button is grouped with a cancel button at the bottom right, on all screen sizes. Fullscreen mobile dialogs have them sticky at the bottom.
 - Keep the labels short, for example `Save`, `Delete`, `Enable`.
