# inject-notes.sh — set per-slide speaker notes via the real PowerPoint app
# (SetSpeakerNotes VBA macro), retiring inject-speaker-notes.py. Real PowerPoint
# serializes valid notes OOXML, so the <p:notesMasterIdLst> Keynote-compat patch
# the python-pptx path needed is no longer required. See rules/deck-editing-rules.md.
# macOS + Microsoft PowerPoint only.
#
# Run this in the build pipeline AFTER the structural walk + illustrations apply
# and BEFORE apply-backgrounds.sh (the VBA background pass must be the final write).
#
# Usage:
#   inject-notes.sh <basePath> <outPath> <notes.json>
#     basePath    the built deck to read (uniquely-named copy)
#     outPath     where to write the COPY with notes applied
#     notes.json  {"<0-based slide #>": "notes text", ...} (the historical format)
#
# Prerequisites: RunDeckOps.bas (which defines SetSpeakerNotes) imported into an
# OPEN macro-enabled deck (DeckOps.pptm), macros enabled, Automation consent granted.
