An iPhone can't run Python or ssh, but the Frame can. The app (ios/, SwiftUI) connects with its own SSH key (Citadel), copies the server and helpers to ~/.cache/frame-control/<version> on the Frame once per version, starts ui/server.py there with FRAME_LOCAL=1 on the Frame's 127.0.0.1, and shows the page through an SSH tunnel. The server exits when the phone disconnects. Server: FRAME_LOCAL=1 puts ui/local-bin on PATH, whose ssh stand-in runs each `ssh frame COMMAND` locally (and serves as rsync's transport), so desktop and phone share one code path. Android display goes through podman exec there, as the Frame has no adb. FRAME_UI_KEY replaces the fixed X-Frame-UI value with a per-session key. Power actions take the Developer Mode password via sudo -S. --port 0 now prints the port it took. Page: a bottom tab bar and safe areas on phones, Play buttons visible on touch screens, saving through the share sheet, SSH/SFTP/Steam Link/remote desktop opening in their iOS apps, and a password dialog for power. App: pairing with the Developer Mode password once (never stored) or with a key the user adds; host key pinned on first use; plain-language connection errors with quiet retries; frame-control://install links; alerts and confirms.

"""Frame Control: a small local web UI for managing the Steam Frame from a computer.
|
|
|
|
Stdlib only; runs on macOS, Linux and Windows (differences live in frame_host.py).
|
|
Listens on 127.0.0.1 and talks to the headset through the `frame` SSH alias set
|
|
up by scripts/connect.sh or ui/frame_connect.py.
|
|
|
|
Usage: ui/server.py [--port 47810] [--exit-on-eof] (normally started by the app)
|
|
Env: FRAME_ALIAS (default frame)
|
|
FRAME_LOCAL=1 run on the Frame itself (the iPhone app starts it there over SSH)
|
|
FRAME_UI_KEY required X-Frame-UI value (the iPhone app passes a fresh one)
|
|
FRAME_DEVICE what to call the device the page runs on (e.g. iPhone)
