### contextBridge

**Documentation:** clipboard module is no longer available in the renderer process ​

**Recommended review:** Keep privileged APIs in preload and expose the smallest possible bridge to the renderer.

- `src/preload/preload.ts:L111`

- `tests/preload/preload.spec.ts:L23`

### desktopCapturer

**Documentation:** NSAudioCaptureUsageDescription should be included in your app's Info.plist file to use desktopCapturer (🍏 macOS ≥14.2) ​

**Recommended review:** Validate macOS screen-capture audio and the app's Info.plist before moving past Electron 39.

### Electron package install
