  # The GPUI product. Kept separate because it pulls a window toolkit, several
  # hundred extra packages, and a large target directory.
  #
  # continue-on-error until this runner's disk, memory, and time budget have
  # actually been measured against a GPUI build. A job that OOMs on every push
  # trains people to ignore CI, which is worse than a job that reports and does
  # not block. Remove the flag once it has run green a few times; do not remove
  # it by assuming it will.
