- Electron main now exposes http://127.0.0.1:9990/screenshot that returns
a PNG via CDP Page.captureScreenshot (GNOME Wayland blocks external
capture, and webContents.capturePage() hangs on this compositor). The
endpoint is localhost-only.
- EMAIL_UPLOAD.md documents the n8n IMAP -> Samba share workflow for
Skylight-style email-to-photo-frame uploads.
