# Morph transition — PowerPoint 2016+ smooth tweening between two slides
# that share named objects. Same shape on adjacent slides with different
# x/y/width/height/rotation is interpolated as continuous motion.
#
# Morph option (-byobject / -byword / -bychar):
#   byobject (default) — shapes with matching IDs are paired and tweened
#   byword             — text body is morphed word-by-word
#   bychar             — text body is morphed character-by-character
#
# This trio is a starter demo. For a fuller scene-level showcase using
# this skill: see examples/product_launch_morph.pptx in the repo root.

# 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.
