- OTA: the player now ends the Spotify session (spotify_suspend: stop flag, waits until the session's tasks are gone, refuses new ones) instead of pausing it, and suspends HLS. Pausing was not enough (an upload still failed once with a paused session). Verified twice with a session running for minutes: "Disconnecting mercury session / session ended / suspended", installed in ~26 s, clean reboot. - Volume: createFromBlob() starts cspot at volume 0, which the app showed while we played at 100 %. The session now starts with the player's volume (spotify_set_volume); volumes coming from the app are stored exactly, without echo. Verified: slider starts at 100 %.
