+            2. Commits:
+               
+               - Is the work split into self-contained commits of reasonable size?
+               - Are the commits arranged in a sensible order?
+               - Have required refactorings been split out into separate commits?
+               - Is the history free of "wip", checkpoint and fixup-style commits
+                 which only correct an earlier commit in the same PR?
+
+            3. Code:
+
+               - Are the code changes functionally correct?
+               - Do the changes introduce new security vulnerabilities or metadata
+                 leaks?
+               - Is the new code performant enough?
+               - Don't check anything that is already validated via other GitHub
+                 workflows like linting, formatting or tests passing.
+
+            Read the commits themselves with `git log` and `git diff` against
+            the base branch of the PR.
+
+            Drop any findings that are outside the above review angles or that don't
+            require resolution. Grade the severity of each finding as either "🟡 low",
+            "🟠 medium" or "🔴 high". Devise at least one possible resolution for each
+            finding.
+
+            Report the graded findings and resolutions from the "Code" angle as inline
+            comments. Add a footer "_-- Finding from automated review_" to each inline
+            comment.
+
+            Finally, report your overall result as PR comment. Start your message with
+            "# Automated review". Then add one section per review angle with:
+
+            - A verdict of "✅ PASS" or "❌ NEEDS WORK"
+            - A bullet list summarizing the remaining non-inlined graded findings and
+              resolutions (as nested bullets).
+
+            Be brief and concise in all your communication. Do not mention what you have
+            not covered and don't bring up issues that have already been fixed.
+
+            Use Markdown links for anything that can be navigated to on GitHub such
+            as files, commits, issues, pull requests, workflow runs, etc.

+
+MatrixRTC (MSC4143) + LiveKit video calling, shipped standalone, as a widget in
+Element Web and Element X, as embedded packages, and as a React component in a
+host's page. It is the MatrixRTC reference implementation.
+
+## Non-negotiables
+
+- Features and UI changes need a pre-approved issue. No issue, no review.
+- Exactly one `PR-*` label per PR. CI enforces it; it drives the changelog.
+- New behaviour ships with unit tests, a story if it renders, and an e2e spec if it
+  is user-facing. All three.
+- Reuse an existing component. If you genuinely cannot, say so in the PR body and
+  name what you rejected — never add a new one silently.
+- Nothing reads the page. No `window.location`, `document.body`, `window.inner*`,
+  `@media`, global `i18next` or the `widget` global — take it from a provider.
+- The change works standalone, as a widget and as a component. Say what you checked.
+- Every gate below is green before you push.
+- Hand off after the first implementation, before the quality pass. Then commit on
+  the user's word where the setup allows it, or hand them the message.

+
+`knip` fails on dead code; a file deliberately inert ahead of its consumer goes in
+`knip.ts` `ignoreFiles` with a reason.
+
+## A good PR
+
+- One slice, under ~400 changed lines, green on its own, linked to its issue.
+- View model + marble tests, thin view, a story per state, an e2e spec.
+- Any new shared component called out explicitly, with why nothing existing fit.
+- Template filled for real: what, why, before/after screenshots, repro steps.
+- Comments only where the code can't give the reason — see
+  [code-style.md](docs/agents/code-style.md#comments).
+- Anything that redraws continuously — an animation frame, a stream — says what it
+  costs, or better, counts the redraws in a test.
+- Branch `<handle>/<topic>`. Plain imperative commit subjects, no prefixes.
+- Once review starts, fix forward. Never force-push a regeneration over a review.

 # Contributing code to Element
 
 Element follows the same pattern as the [matrix-js-sdk](https://github.com/matrix-org/matrix-js-sdk/blob/develop/CONTRIBUTING.md).
+
+# Contributing to Element Call
+
+Element Call is a native Matrix video conferencing application built on
+[MatrixRTC (MSC4143)](https://github.com/matrix-org/matrix-spec-proposals/pull/4143)
+and [LiveKit](https://livekit.io/). It runs in multiple deployment contexts — as a
+standalone web app and as a widget embedded in Element Web, Element X iOS, and
+Element X Android. It is also the primary R&D foundation for MatrixRTC, which means
+its architecture, maintainability, and flexibility are held to a high standard.
+
+We welcome contributions from the community. This document explains how to
+contribute effectively so that both you and the maintainers get the best outcome.
+
+## Issue First Policy
+
+> [!IMPORTANT]
+> Before writing a single line of code for a new feature or UI change, you **must**
+> open an issue and have the approach agreed with the maintainers.
+>
+> **We will not review or merge feature or UI pull requests that arrive without a
+> corresponding, pre-approved issue.**
+
+This is not gatekeeping — it's how we prevent wasted effort on both sides. Element
+Call must work correctly across multiple deployment contexts and meet specific product
+and design requirements. It is also a fast-moving codebase that underpins ongoing
+MatrixRTC development. A PR that looks reasonable in isolation can easily conflict
+with in-progress work, planned architecture changes, or design decisions that haven't
+been publicly documented yet.
+
+The issue is where we resolve all of that **before** anyone writes code.
+
+**Bug fixes** are no exception — most confirmed bugs should already have an issue anyways, existing issues that are marked as bugs have an implicit maintainer approval. If the solution for the bug is controversial it is highly recommended to discuss the approach in the issue before opening a PR.
+
+## Contribution Workflow
+
+1. **Open an issue** using the [Enhancement request](https://github.com/element-hq/element-call/issues/new?template=enhancement.yml) template.
+2. **Wait for feedback.** A maintainer will comment on the issue **within two weeks**. The use case and approach will get dicussed.
+   This may involve questions, suggestions, or a request to adjust scope.
+   This also allows to bring design and product into the loop before code gets created.
+3. **Get a green light.** Wait for explicit approval from a maintainer before starting
+   implementation.
+4. **Implement.** Write the code against the agreed approach.
+5. **Open a PR.** Link to the issue in your PR description and satisfy the checklist
+   in the PR template.
+
+## Code Quality
+
+Element Call moves fast and the codebase must stay clean and maintainable.
+
+- **Take responsibility for AI-generated code.** AI tools can be a useful aid, but we expect all the generated code to be understood and reasoned about by the contributor. Questions by the maintainers should be answered without just forwarding them to AI. The maintainers also have access to AI tools. If your contribution is just transporting messages between LLM <-> maintaines all our time is better used if the maintainers decide to interact with AI for this specific problem by themselves.
+- **Think across deployment contexts.** Changes must work correctly in both standalone
+  and widget modes. Consider how your change interacts with Element Web, Element X
+  iOS, and Element X Android.
+- **Write tests.** New functionality should be covered by tests. Where it is feasible,
+  existing uncovered code touched by your PR should also gain tests.
+
+## Contributor License Agreement
+
+All contributors must sign the
+[Element Contributor License Agreement](https://cla-assistant.io/element-hq/element-call)
+before their contribution can be merged. The CLA assistant bot will prompt you
+automatically when you open a PR.
+
+## Getting Help
+
+The best place to ask questions about Element Call development is the MatrixRTC room:

+#### Element Call as a component (experimental)
+
+Element Call can also be embedded directly into another React application
+rather than being loaded in an iframe as a widget. `pnpm build:component`
+builds it as a library into `component/dist` (the bundle, its stylesheet and
+type declarations), and
+
+```sh
+pnpm dev:component
+```
+
+serves a harness on port 3001 that stands in for such an application: it signs
+in twice against the development backend and shows two calls side by side, in
+resizable boxes, with page furniture of its own around them. Use it to see how
+Element Call behaves when it does not own the page — the size it is given,
+whether it stays inside its container, and what it says to its host, which is
+logged along the bottom. The harness is served with the same development
+certificate as the app, so unless the development CA is trusted, the browser
+needs a certificate exception for `https://localhost:3001` as well (see the
+note under [Backend](#backend)). It reads the same `public/config.json` as
+`pnpm dev` if one exists, and runs with Element Call's defaults otherwise.
+
+The call lays itself out for the size of the element it is mounted in, not the
+window: a host that shrinks the container to a corner of its page gets the
+picture-in-picture layout, just as a host that shrank the whole iframe used to.
+The breakpoints in the stylesheets the component uses are
+`@container element-call` queries against its root element for the same reason;
+for the standalone app the root is the page, so they mean what the media queries
+they replaced did. (The standalone-only views, such as the home and login pages,
+still use plain media queries, since the component never shows them.)
+
+The component's stylesheet is confined to the element it is mounted in: the
+build rewrites every selector so that it matches only Element Call's root or
+what is inside it, with `html`, `body` and `:root` standing for that root (see
+`component/build/scopeStylesToRoot.ts`). A host's own page keeps its styles,
+and Element Call brings its own fonts and design tokens along.
+
+The component speaks every language the app does. English is bundled in; the
+other locales are split into chunks the host's bundler loads the first time
+they are needed. It starts in the browser's language, and follows the host's
+own language setting through the `language` prop (`supportedLanguages` lists
+the tags it accepts, and anything else falls back to its base language or to
+English). The `theme` prop works the same way and takes the same values as the
+widget's `theme` URL parameter: `light`, `dark`, `light-high-contrast` or
+`dark-high-contrast`. Both can change while a call is running without
+disturbing it.
+
+A host must call and await `initializeElementCall(config)` once before
+rendering the component: it loads the `Intl` polyfills, applies the
+deployment-wide `config.json`-style configuration and sets up translations.
+The component itself takes the host's `client` and the `roomId` to call in, an
+`intent` saying what the user asked for (which decides whether to show the
+lobby, ring, and so on), an optional `config` overriding what the intent
+implies, and an optional `hostBridge` through which Element Call tells the host
+that the user has joined or hung up, that it wants to stay on screen, and so
+on. The host makes its own requests (`join`, `hangUp`, `setDeviceMute`) through
+the handle exposed on `ref`. The full API is documented in the type declarations
+(`component/index.tsx` and `component/host.ts`).
+
+A few things differ from the widget on purpose: the component draws a solid
+background rather than a gradient unless told otherwise, never offers to edit
+the user's profile (the account is the host's), scopes its keyboard shortcuts to
+its own root element so that several instances can share a page, and only shows
+its own post-call and error screens when the host has not supplied a `close()`
+callback; with one, it asks the host to unmount it instead. The
+[global JS controls](./docs/controls.md) on `window` are unchanged and remain
+page-wide, so with several instances on one page they apply to all of them.
+
+The package is not published yet. A host installs it as a git dependency on the
+`component` directory of this repository,
+
+```json
+"@element-hq/element-call-component": "github:element-hq/element-call#main&path:/component"
+```
+
+whose `prepare` script runs the build on install. That build needs pnpm (via
+Corepack) on the host's machine, runs a full `pnpm install` of this repository,
+since it inherits the `--max-old-space-size` setting of
+the app build; the host's pnpm also has to allow it to run at all
+(`allowBuilds` in its `pnpm-workspace.yaml`). Note that `component/` is a pnpm
+project of its own for this reason, so pnpm commands run from inside that
+directory target it rather than the repository; run them from the repository
+root. The host imports the component from
+`@element-hq/element-call-component` and the stylesheet from
+`@element-hq/element-call-component/style.css`, and has to provide `react`,
+`react-dom`, `matrix-js-sdk`, `@vector-im/compound-web` and
+`@vector-im/compound-design-tokens` itself, since the bundle leaves them
+external.
+Compound's stylesheet are the host's to load too: the component shares
+the host's copy of Compound, (required for example for tooltips)
+
+The component is large, and a host will usually load it lazily, only once a
+call is shown. Everything a host needs in order to talk about a call before
+then is also exported
+from `@element-hq/element-call-component/api` (a small entry point that does not
+load the component).

+
+## Testing on Mobile Devices
+
+When developing Element Call locally, you may want to test on physical mobile devices (iOS/Android)
+on the same WiFi network.
+
+**Known Limitations:** For now this setup allows to use your local EC server but not yet the SFUs and Synapses.
+
+### Prerequisites
+
+1. **Start the dev server**
+
+   ```bash
+   pnpm dev
+   ```
+
+Check the output for the `➜  Network` (this will contain the local IP address of your laptop)
+
+```
+  ➜  Local:   https://m.localhost:3000/                                                                                                                                                                 12:06:48
+  ➜  Local:   https://vite.m.localhost:3000/                                                                                                                                                            12:06:48
+  ➜  Local:   https://vite.othersite.m.localhost:3000/                                                                                                                                                  12:06:48
+  ➜  Local:   https://vite.nip.io:3000/                                                                                                                                                                 12:06:48
+  ➜  Network: https://192.168.0.122:3000/
+```
+
+2. **Transfer the CA certificate to your phone**
+
+   The file is located at `backend/dev_tls_local-ca.crt`. Transfer it via:
+   - Matrix room
+   - AirDrop for iphone
+
+### IOS Setup
+
+**Install the certificate profile on iPhone**
+
+- Open the `dev_tls_local-ca.crt` file on your iPhone
+- You'll see "Profile Downloaded"
+- Go to **Settings → General → VPN & Device Management** (or **Settings → General → Profiles**)
+- Tap the "Element Call Dev CA" profile
+- Tap **Install** and enter your passcode
+- Confirm by tapping **Install** again
+
+**Enable full trust (Critical!)**
+
+- Go to **Settings → General → About → Certificate Trust Settings**
+- Under "Enable Full Trust for Root Certificates"
+- Toggle **ON** for "Element Call Dev CA"
+- Confirm the security warning
+
+**Access Element Call**
+
+Find your laptop's IP address (e.g., `192.168.0.122`) and use one of these URLs in Safari to validate:
+
+```
+https://192-168-0-122.nip.io:3000/
+```
+
+**For Element X iOS Developer Tools**
+
+In Element X's developer settings, set the Element Call URL to the nip.io url (replace . with - in the IP address):
+
+```
+https://192-168-0-122.nip.io:3000/room
+```
+
+### Android Setup
+
+**Transfer the CA certificate to your Android device**
+
+The file is located at `backend/dev_tls_local-ca.crt`.
+
+**Install the certificate**
+
+This might vary by Android version and manufacturer, but generally:

+- Open **Settings** search for "CA Certificate"/"Certificate"
+- Tap **Install a certificate** or **Install from storage**
+- Select **CA certificate**
+- Confirm the security warning
+- Navigate to and select the `dev_tls_local-ca.crt` file
+- Give it a name like "Element Call Dev CA"
+
+**Access Element Call**
+
+Find your laptop's IP address (e.g., `192.168.0.122`) and use one of these URLs in Chrome to validate:
+
+```
+https://192-168-0-122.nip.io:3000/
+```
+
+**For Element X Android Developer Tools**
+
+In Element X's developer settings, set the Element Call URL to the nip.io url (replace . with - in the IP address):
+
+```
+https://192-168-0-122.nip.io:3000/room
+```
+
+### Why nip.io?
+
+[nip.io](https://nip.io) is a free wildcard DNS service that automatically resolves domain names containing IP addresses. For example, `192-168-0-122.nip.io` automatically resolves to `192.168.0.122`. This means:
+
+- No need to regenerate certificates when your laptop's IP changes
+- Works from any device without DNS configuration
+- iOS/Android treat it as a proper domain name, not an IP address
+- One-time certificate setup works for all future IP addresses
+
+> [!IMPORTANT]
+> Make sure your network router doesn't enforce DNS rebinding protection (which will
+> break nip.io). If it does, try allow-listing nip.io in your router's administration interface.

+# Architecture
+
+## Logic lives in view models; components render
+
+- Call logic lives in `src/state/`. A component that derives call state is
+  misplaced logic.
+- Composing behaviors: a factory taking `(scope, ...deps$)`, returning named
+  behaviors plus callbacks. Copy `src/state/LayoutSwitchViewModel.ts`. Prefer this
+  for anything new.
+- Owning a resource: a class taking the scope in its constructor — `MediaDevices`,
+  `MuteStates`, `TileStore`, `Publisher`, `Connection`. Both styles are current;
+  don't convert one to the other in passing.
+- `foo$` is an observable. `Behavior<T>`, an observable with a current value, is
+  the default for anything a view reads.
+
+## The view model / view contract
+
+- Components take `vm: ViewModel<Snapshot>` and read state through `useBehavior`.
+  See `CallFooter`, `InCallView`, `LobbyView`, `SettingsModal`.
+- A snapshot is `Actions & State`; every field becomes a `foo$` behavior, and none
+  is optional.
+- An unavailable action is `undefined`, not a separate `canDoThing` flag — the
+  presence of the callback drives the rendering.
+- Subscribe in an effect only to drive a side effect off an event stream, as
+  `ReactionAudioRenderer` does; never to read state a behavior already holds.
+
+## Scopes own lifetimes
+
+- `ObservableScope` bounds every subscription a view model creates.
+- Reference only the scope defined in the same function; one captured from an
+  enclosing scope outlives its owner, and `no-observablescope-leak` rejects it.
+
+## Nothing reads the page
+
+Element Call can be mounted several times inside a host's React tree, so it owns
+neither window, URL, document nor router. Each seam defaults to the old standalone
+and widget behaviour.
+
+| Never                                         | Use                                                           |
+| --------------------------------------------- | ------------------------------------------------------------- |
+| the `widget` global                           | `useHostBridge()` — `src/HostBridge.ts`                       |
+| `getUrlParams()`, `window.location`           | `useUrlParams()`                                              |

+| config or analytics reading their environment | `Config.initWith()`, `PosthogAnalytics.configure()`           |
+
+- View models take values as options, never `getUrlParams()`
+  (`callViewModelOptionsFromParams`, `CallViewModelOptions.hostBridge`).
+- The host bridge is the only channel to the host: `createWidgetHostBridge(widget)`,
+  `nullHostBridge` standalone, `useComponentHostBridge`. State a capability
+  (`supportsReactions`, `supportsProfileChanges`); never infer it from being a
+  widget.
+- Shortcuts and portals attach to the root element, so two instances don't fight.
+- Known debt, not precedent: `Grid` measures `window.innerHeight`; `ErrorView`'s
+  reload and `getAbsoluteRoomUrl` use `window.location`; recaptcha appends to
+  `document.body` on the standalone login path.
+
+## Context differences are options, not checks
+
+- Named options with per-intent defaults (`configurationForIntent`), never a
+  runtime check for who is hosting.
+- `controlledAudioDevices`, not the platform, is what makes `MediaDevices` pick
+  `AndroidControlledAudioOutput` / `IOSControlledAudioOutput` over the web
+  `AudioOutput`. Intent presets set it on non-desktop; standalone leaves it off.
+- URL params are a published contract: change one, update `docs/url_params.md`.
+
+## Build targets
+
+Code that builds in only one is a bug.
+
+- `build:full` — standalone app, also widget mode.
+- `build:embedded` — `@element-hq/element-call-embedded`.
+- `build:sdk` — SDK library, entry `sdk/main.ts`.
+- `build:component` — `@element-hq/element-call-component`, sources in `component/`
+  (its own pnpm project; run pnpm from the repo root). Host API is in the README;
+  `pnpm lint:externals` rejects an import of a `react` / `react-dom` /
+  `matrix-js-sdk` / `@vector-im/compound-web` /
+  `@vector-im/compound-design-tokens` subpath the externals list omits.
+  `livekit-client` is bundled on purpose: no host imports it, and the pinned
+  version travels with the component.
+  Compound's stylesheets are loaded by `src/index.css` for the page and by the
+  host for the component, never by `src/base.css`. Two entry
+  points: `index.tsx` (the component) and `api.ts` (types, enums and
+  `configurationForIntent`, for a host that must not load the component). `api.ts`
+  may only reach types and constants — `src/UrlConfiguration.ts`, not `UrlParams`.

+# Code style
+
+_Clean Code_ (Robert C. Martin): small functions, intention-revealing names, low
+noise.
+
+## Reuse before you build
+
+Look before you write, in this order:
+
+1. **Compound Web** — `@vector-im/compound-web` for buttons, tooltips, alerts,
+   dialogs, menus, form controls, avatars; icons in
+   `@vector-im/compound-design-tokens/assets/web/icons`.
+2. **This repo** — `src/button/`, `src/components/`, `src/input/`, `src/form/`,
+   `src/tabs/`, and `Modal`, `Avatar`, `Toast`, `Slider`, `ErrorView`,
+   `FullScreenView` at the root of `src/`.
+3. **The nearest existing feature** — grep for the same shape first. A hook is
+   often what you want to extract, not a component.
+
+If nothing fits, name the new shared component in the PR body and say what you
+rejected and why — never add one silently. Extend or parameterise before forking,
+and extract shared logic into a hook both callers use before copying it; if you
+copy, the PR says so.
+
+## Ordering
+
+- **Newspaper order.** Headline first, detail down. A file opens with what it
+  exists to provide.
+- **Stepdown rule.** Caller above callee. A helper used by one function sits
+  beneath it, which needs a `function` declaration, not a `const` arrow. Existing
+  arrow components above their callers are not a pattern to extend — nor to churn.
+- **Suites.** Test cases first, helpers below. Older suites invert this; follow the
+  rule in new ones, don't reorder old ones.
+- **Names.** What a thing means, not what it is made of: `naturalLayout$`, not
+  `computedLayout$`.
+
+## Comments
+
+No comment is the default. One earns its place by giving a reason the code
+cannot: a platform quirk, an outside constraint, a trap that looks like a
+simplification.
+
+- Say the reason, then stop. Test each sentence: does the reason still stand
+  without it? If so, cut it. Most reasons fit on a line, so a long comment is
+  worth a second look — it is usually carrying something that isn't one.
+- Write about the line the comment sits on, in terms of what the code does
+  there — leave layout to the stylesheet and measurements to the design.
+- Name the condition ("where the platform can't route audio"), not the browser
+  or the spec entry.
+- Put history — what was tried, removed or rejected, the dev journal — in the
+  commit or the PR description.
+- In tests, comment only structure that looks wrong but isn't: batching, timers,
+  why this scroll position.
+
+Before keeping one: would it still be true after a CSS change or a refactor of
+its caller? If not, cut it.
+
+## TypeScript, React and RxJS idiom win on a clash
+
+- Hooks stay unconditional at the top of a component.
+- `useCallback` / `useMemo` dependency arrays sometimes force inlining.
+- An RxJS pipeline stays one expression. Name the behavior, not each operator.
+- A long factory is fine when it reads as a list of named behaviors.
+  `CallViewModel.ts` is long because the domain is.
+- Marble test tables are dense on purpose.
+
+## Enforced by lint
+
+- Copyright header on every file: `Copyright <current year> Element Creations Ltd.`
+  plus the AGPL / commercial SPDX line.
+- `logger` from `matrix-js-sdk/lib/logger`, never `console`, and no top-level
+  `logger.getChild()`. The `console` ban is only enforced under `src/*/**`.
+- No floating or misused promises; async functions typed `Promise<T>`.
+- Inline type imports (`import { type Foo }`), so matrix-js-sdk stays lazily
+  loadable.
+- Deep-import `matrix-js-sdk/lib/<module>` as the codebase does. Banned is the bare
+  `matrix-js-sdk/lib`, `lib/index` and anything under `src/`.
+
+## CSS
+
+- Compound components and `--cpd-*` tokens in CSS modules. A hardcoded colour or px
+  spacing is a design question, not a licence to inline a hex.
+- Size against the root, not the window: `@container element-call (…)` and
+  `cqw` / `cqh`, never `@media (width)` or `vw` / `vh`. Media queries stay correct
+  only in standalone-only views — home, login.
+- Style `[data-element-call-root]`, never `body` or `:root`; the component build
+  makes those stand for the root (`component/build/scopeStylesToRoot.ts`).
+
+## Strings and a11y
+
+- Strings through `t()`: add the key, run `pnpm i18n`, fill `locales/en/app.json`.
+  Other locales come from Localazy; never hand-edit them.
+- `t` from `useTranslation()`, or `src/utils/i18n.ts` outside React. Never the
+  `i18next` global — several instances share a page.
+- Accessible names on controls, `aria-pressed` on toggles, keyboard reachability.
+  `jsx-a11y` rules are errors; `vitest-axe` is available.

+Storybook proves the rendering, e2e proves the feature. Codecov gates 80% on the
+lines a PR touches.
+
+## Unit
+
+- View model tests use `withTestScheduler` + `testScope()` from `src/utils/test.ts`
+  and read as ASCII timelines. Copy `LayoutSwitchViewModel.test.ts`.
+- Component tests use Testing Library, queried by role and accessible name.
+- Reuse the factories in `src/utils/test.ts` — `mockRemoteParticipant`,

+  render calls. An effect with no dependency array runs once per commit.
+- `component/**/*.test.ts` runs in the same jsdom project as `src`.
+
+## Storybook
+
+A deliverable, not documentation: `pnpm test:storybook` runs every story as a real
+browser test in the same CI job as the unit suite. **A UI change without a story is
+incomplete.** Only three stories exist so far, so copy `CallFooter.stories.tsx`.
+
+- Drive the component from a snapshot via `useStaticViewModel`, never internals.
+- One named story per state that matters — loading, error, empty, denied, mobile.
+- Assert in a `play` function with `userEvent` / `expect` from `storybook/test`.
+- Mobile is `globals: { viewport: { value: "mobile2" } }`, not a second component.
+- Expose interesting props through `argTypes`.
+
+`.storybook/preview.tsx` supplies `TooltipProvider`, `src/index.css` and English
+translations. The browser is Playwright's, so a fresh clone needs
+`pnpm playwright install` once.
+
+## End-to-end
+
+- `playwright/*.spec.ts` — standalone, on Chromium and Firefox.
+- `playwright/widget/` — widget mode, where cross-context bugs surface.
+- `playwright/component/` — the component in a host page, via the harness on port
+  3001 that Playwright starts as a second web server. Catches container-relative
+  layout, styles escaping the root, two instances on a page, host-bridge reports.
+- `playwright/mobile/` — Pixel 7, `mobile` project only.
+
+Test what a user observes: the peer sees the change, it survives a reconnect, it is
+right after a reload. Reuse `playwright/spa-helpers.ts`,

These functions must be enabled using the URL parameter `controlledAudioDevices` to take effect.

+## Testing against a matrix-js-sdk branch in CI

+Linking covers local development. In CI, `scripts/layered.sh` plays the same
+role for `matrix-js-sdk`: after the usual frozen install, `scripts/fetchdep.sh`
+looks for a matrix-js-sdk branch with the same name as the pull request's head
+branch (in the fork first, when the pull request comes from one). If there is
+one, it is cloned, packed and installed over the locked version. If there is
+none, the install stays as `pnpm-lock.yaml` pins it.
+
+This means a change that needs a not yet merged matrix-js-sdk change can be tested
+by giving both branches the same name. This mirrors how element-web tests against
+matrix-js-sdk. Once the matrix-js-sdk branch is merged and deleted, the pull
+request falls back to the lockfile and needs a lockfile bump to stay green,
+which is also what keeps `main` consistent after the merge.

+# MatrixRTC modes
+
+Element Call is in the middle of a transition of how a call session is
+represented: from room _state_ events (`org.matrix.msc3401.call.member`) to
+_sticky_ events
+([MSC4354](https://github.com/matrix-org/matrix-spec-proposals/pull/4354)),
+which are a much better fit for the short lived, per-device nature of call
+memberships.
+
+Not every homeserver supports sticky events yet. The two MatrixRTC modes
+controls whether Element Call uses them.
+
+## The modes
+
+| Mode            | Membership events | SFU selection | JWT endpoint                 |
+| --------------- | ----------------- | ------------- | ---------------------------- |
+| `compatibility` | state events      | multi SFU     | legacy                       |
+| `matrix_2_0`    | sticky events     | multi SFU     | Matrix 2.0 (hashed identity) |
+
+**`compatibility`** — multi SFU, but still state events. Use it when the
+homeserver does not support sticky events. This is the default.
+
+**`matrix_2_0`** — the target state. Requires a homeserver that advertises
+MSC4354 and all clients on v0.17.0 or later. The local membership requests its
+token from the Matrix 2.0 JWT endpoint of the
+[MatrixRTC Authorization Service](https://github.com/element-hq/lk-jwt-service)
+and identifies the room by a hashed identity instead of the Matrix `room_id`.
+(Remote memberships always try the new endpoint first and fall back to the
+legacy one, so remote participants can be on either.)
+
+## Selecting a mode
+
+Users can choose a mode under **Settings → Developer → MatrixRTC mode**. The
+Matrix 2.0 option is disabled if the homeserver does not support sticky events.
+
+A deployment can pin the mode for all its clients in `config.json`, which
+disables the Developer Settings choice:
+
+```json
+{
+  "matrix_rtc_mode": "compatibility"
+}
+```
+
+Valid values are `compatibility` and `matrix_2_0`; an invalid value is
+ignored (with a warning) and the user's choice applies. Pinning `matrix_2_0` on a
+homeserver without sticky event support makes joining fail with a "sticky events
+required" error.
