For ordinary React Native performance or architecture issues, use [react-native-best-practices](..\u002Freact-native-best-practices\u002FSKILL.md).\n\n## Skill Format\n\nReference files are grouped by topic prefix:\n\n- `focus-*`: focus engines, focus guides, focus event performance\n- `nav-*`: D-pad navigation, Back\u002FMenu behavior, keyboard\u002Fsearch input\n- `design-*`: 10-foot typography, layout, color, focus visibility\n- `perf-*`: startup, memory, lists, animation, and network constraints on TV hardware\n- `video-*`: playback architecture, DRM\u002Fprotocol selection, debugging\n- `a11y-*`: TV accessibility implementation and audit checks\n- `setup-*`: stack detection, setup, architecture, cross-platform behavior\n- `test-*` and `release-*`: test coverage, E2E, and CI\u002Frelease workflows\n\n## When to Apply\n\nApply this skill when the app targets a TV platform and the work involves:\n\n- Focus movement, visible focus, focus restoration, or remote\u002FD-pad input\n- TV layout readability, overscan\u002Fsafe areas, or 10-foot UI density\n- TV player controls, manifests, DRM, decoder support, or playback errors\n- Performance on low-memory TV hardware, especially with video or large carousels\n- TV accessibility with screen readers, captions, focus order, or remote-only interaction\n- Platform setup for `react-native-tvos`, Expo TV, Amazon Vega\u002FKepler, Tizen, or webOS\n\n## Before You Start — Identify the TV Stack\n\nThis skill covers several TV stacks. **Detect which one the app targets before flagging setup issues** — demanding `react-native-tvos`, a tvOS Podfile, or an Android TV manifest on a Vega\u002FKepler or web-based TV app produces false positives.\n\n| Stack                                                 | How to detect                                                                                     | Setup expectations                                                                                                             |\n| ----------------------------------------------------- | ------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |\n| **react-native-tvos** (Apple TV, Android TV, Fire TV) | `\"react-native\": \"npm:react-native-tvos@…\"` in package.json                                       | tvOS Podfile (`platform :tvos`); Android TV `leanback`\u002F`LEANBACK_LAUNCHER` manifest entries; TV emulator\u002Fsimulator             |\n| **Expo + react-native-tvos**                          | above **plus** `@react-native-tvos\u002Fconfig-tv` in app.json                                         | `EXPO_TV=1` prebuild; `react-native-tvos` version must match the Expo SDK; not all Expo features\u002Flibraries are available on TV |\n| **Amazon Vega \u002F Kepler**                              | Vega\u002FKepler SDK & tooling (`@amazon-devices\u002F*` deps, Kepler manifest); **no** `react-native-tvos` | Amazon's Vega\u002FKepler toolchain — `react-native-tvos`, tvOS Podfile, and Android TV manifest do **not** apply                   |\n| **Web-based TV** (Tizen, webOS)                       | web bundler (Rsbuild\u002Fwebpack) + platform packaging; spatial-nav library                           | Platform SDK packaging; `@noriginmedia\u002Fnorigin-spatial-navigation` for focus                                                   |\n\nThe focus, 10-foot design, performance, accessibility, and player guidance applies across all of these — only the **setup\u002Fbuild** expectations are stack-specific.\n\n## Review Rules\n\n- Resolve the target stack before setup advice.\n- Prefer natural focus order and focus guides before imperative focus calls or broad `nextFocus*` maps.\n- Treat focus loss, invisible focus, and broken Back\u002FMenu behavior as navigation bugs.\n- Check readability, safe areas, and focus states at TV distance before tuning visual details.\n- Profile on the weakest supported TV device before reporting performance fixes as complete.\n- Separate playback failures by layer: manifest request, DRM license exchange, decoder capability, player state, and React UI controls.\n\n## Priority-Ordered Guidelines\n\n| Priority | Category | Impact | Prefix |\n|----------|----------|--------|--------|\n| 1 | Focus and D-pad navigation | CRITICAL | `focus-*`, `nav-*` |\n| 2 | List, animation, and input performance | CRITICAL | `perf-*` |\n| 3 | Playback and DRM failures | HIGH | `video-*` |\n| 4 | 10-foot readability and layout | HIGH | `design-*` |\n| 5 | TV accessibility | HIGH | `a11y-*` |\n| 6 | Stack setup, testing, and release | MEDIUM | `setup-*`, `test-*`, `release-*` |\n\n## Quick Reference\n\n1. Detect the TV stack from package files, manifests, native folders, and platform tooling.\n2. Reproduce navigation with the remote or D-pad path, not mouse\u002Ftouch assumptions.\n3. Confirm the focused element is always visible, reachable, and restored after modals\u002Froutes.\n4. Check playback failures from the network\u002FDRM layer upward before changing React controls.\n5. Measure list, animation, memory, and startup work on the weakest supported TV target.\n\n## References\n\n### Focus and Navigation\n\n| File | Impact | Description
