// The upload watch's household line: qBittorrent's page says the limit while the BOX owns it — in the reader's
// language — and says nothing when the household owns it (the view then carries 0), when no view is wired, or on
// another app's page.
// RED-PROOF: drop the `.QBLimitNote` card from app_shell.html → the first case fails; drop the slug check in the
// handler → crafty's page carries the line → fails.
