# Directional transitions — push, cover, uncover/pull, wipe.
#
# Direction support is NOT uniform across the family:
#   - push:           up/down/left/right                       (4 dirs)
#   - wipe:           up/down/left/right                       (4 dirs)
#   - cover/uncover:  up/down/left/right + leftup/rightup/
#                     leftdown/rightdown                       (8 dirs)
#   - pull:           alias for uncover                        (same 8 dirs)
#
# Mismatching the family/direction triggers an OOXML schema-level error
# from officecli (e.g. 'push-leftup' is rejected — push only supports the
# four cardinal directions). See transitions-basic.sh for the no-direction
# transitions (cut/fade/dissolve/flash).

# 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.
