      # Advisory only for now: this compares against the last *published* npm
      # version, which predates a large batch of legitimate feature merges
      # landed in one session — a real ~77% size increase, not a regression
      # introduced by any single PR. Re-enable as a hard gate (remove
      # continue-on-error) once a new version is published to npm and this
      # baseline is current again.
