# Random transitions — PowerPoint picks the actual animation at render
# time, so the .pptx only captures the intent, not the specific motion.
#
#   newsflash — newspaper-style spin-and-zoom (one fixed animation, but
#               grouped with the random family because it's pre-2010
#               legacy and rarely used outside this slot).
#   random    — PowerPoint chooses a random transition each time you
#               enter Slide Show mode.

# NOTE: intentionally NO `set -e`. Like the SDK twin's doc.batch, this script
# tolerates forward-compat 'UNSUPPORTED props' warnings (officecli exit 2) and
# keeps building so the full document is produced.
