# Does three things: start the queue server if it's down, keep the Mac awake, and
# open OR focus a single Flow tab in Brave (never spawns duplicates).
#
# Scheduled every 10 min via launchd for self-healing (see install.sh).
# NOTE: launchd can't execute scripts inside ~/Documents (macOS TCC blocks it),
# so the agent runs a COPY at "~/Library/Application Support/flowrinse/" —
# after editing this file or local_server_example.py, re-run ./install.sh to resync.

# tick an existing tab is re-selected inside Brave without yanking you out of
# whatever you're doing. Selecting the tab also keeps Memory Saver from discarding it.
