# During a sync, `newsup` writes the spinner to /tmp/newsupdate; show that.
# Otherwise read the unread count directly from newsboat's cache.db in
# read-only mode. We deliberately avoid `newsboat -x print-unread`: it needs
# the cache.db lock and prints NOTHING (exit 1, "an instance is already
# running") whenever another newsboat holds it — an open session or a slow
# `-x reload` — which blanked/flickered the block. A read-only+immutable query
# never locks, so it always returns the live count even mid-reload.
# NOTE: this counts every unread item in the DB, which matches print-unread
# only while the DB has no feeds outside ~/.config/newsboat/urls. If you remove
# a feed from urls, purge its leftover items so the count stays accurate:
#   newsboat (open and quit once — cleanup-on-quit prunes orphaned feeds)
