The cover was previously only wired through the UI hook; --play skipped it. Also: Bun's fetch hangs in compiled binaries (Bun 1.3.8) — every cover download silently failed in shipped builds, timing out against any host. Cover staging now shells out to curl (present on macOS/Linux, 8s bound), shared via src/utils/cover-art.ts so the UI and CLI paths stage the same temp file and pass it to mpv as --cover-art-files (albumart track).

/**

|
* Cover-art staging for the system Now Playing session.
|
|
*
|
|
* macOS shows the media session's albumart in the audio center (Control
|
|
* Center / lock screen). mpv reads it from `--cover-art-files` (loads the
|
|
* file as an albumart video track), so the podcast cover is staged to a temp
|
|
* file BEFORE playback starts and passed to mpv.
|
|
*
|
|
* Downloaded via `curl` (not `fetch`): Bun's `fetch` hangs in compiled
|
|
* `bun build --compile` binaries (Bun 1.3.8), timing out on any host —
|
|
* which would silently drop every cover in shipped builds. curl is present
|
|
* on macOS and Linux. Bounded: a slow cover server must never stall audio,
|
|
* so an 8s cap drops the art.
