iPhone and iPad app: the same features, served from the Frame
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.

"""Pack what Frame Control's server needs to run on the Frame itself (the files the
|
||||
desktop app ships, plus ui/local-bin) into one reproducible .tar.gz.
|
||||
|
||||
The iPhone app copies it to ~/.cache/frame-control/<version> on the Frame and
|
||||
starts ui/server.py there. <version> is the SHA-256 of the archive, so a new
|
||||
build replaces an old one and an unchanged one isn't copied again.
|
||||

||||
Usage: make_frame_bundle.py OUT.tar.gz (prints the version)
