Adds a new server endpoint as a method on `app/js/api/ApiClient.js` and exposes it via the matching singleton manager (`AuthManager`, `SessionManager`, `LibraryManager`, `PlayerManager`). Use when the user says 'add endpoint', 'new API method', 'wrap /Items/...', 'call the server for X', or adds code under `app/js/api/`. Capabilities: writes the `ApiClient` method using `this.request(method, path, body, options)`, builds query strings with `URLSearchParams`, throws `ApiError` on failure, exposes a thin manager wrapper that logs via `Logger.error`, and adds matching Jest tests under `tests/unit/api/`. Do NOT use for direct `fetch` calls from views/components, for HLS `.m3u8` stream URLs (those go through `app/js/player/HlsPlayer.js`), for new auth flows that change token/session storage shape, or for changes to the device-profile payload itself.

Adds a new server endpoint as a method on `app/js/api/ApiClient.js` and exposes it via the appropriate manager (`AuthManager`, `SessionManager`, `LibraryManager`, `PlayerManager`). Uses `this.request(method, path, body, options)` with `URLSearchParams` for query strings and `ApiError` for failures. Use when user says 'add endpoint', 'new API method', 'call /Items/...', or adds code under `app/js/api/`. Do NOT use for direct `fetch` calls from views, for HLS streaming URLs (those go through `getItemPlaybackInfo`), or for editing the `deviceProfile` shape.

Adds a Jest jsdom unit test at tests/unit/<layer>/<File>.test.js mirroring the source layout under app/js/<layer>/, importing the class (not the singleton) for fresh beforeEach instances. Follows the describe/describe/it('should …') pattern from tests/unit/api/ApiClient.test.js, tests/unit/utils/Helpers.test.js, and tests/unit/remote/KeyMapping.test.js. Use when user says 'write a test', 'add unit test', 'test this', 'jest test', or after adding new code to app/js/. Do NOT use for integration tests under tests/integration/ (directory does not exist yet — the npm script passes empty), Tizen widget signing tests, or non-Jest test runners.

Wires a new Samsung Tizen remote action by updating `KEY_MAP`, `isRepeatable`/`isImmediate` classification, and `getDisplayName` in `app/js/remote/KeyMapping.js`, then handles it in `PlayerRemoteHandler.js` or the global navigation handler. Use when user says 'add remote key', 'handle MediaPlayPause', 'map color button', 'wire a new remote action', or modifies anything under `app/js/remote/`. Capabilities: keycode-to-action mapping, repeat vs immediate classification, display-name registration, handler wiring during playback vs navigation, KeyMapping unit-test updates. Do NOT use for raw `document.addEventListener('keydown')` outside `RemoteManager` (forbidden — all remote input flows through the singleton), for adding browser/mouse/pointer events (TV has none), or for editing `hls.js` quality keys (use the player skill instead).

Creates a new view class under app/js/ui/ following the show()/hide()/load(params) lifecycle, registers it in App.js view map, and wires a hash route via Router.addRoute('/path', handler). Handles manual focus with .focusable + .selected classes and Enter keydown (no pointer/mouse events). Use when user says 'add view', 'add screen', 'new page', 'add route', or creates files under app/js/ui/. Do NOT use for player overlay controls (extend PlayerView.js methods like toggleInfoPanel/cycleSubtitles instead), for non-routed reusable components, or for API/manager classes (those live under app/js/api/).
