# run-deck-ops.sh — trim / reorder / cross-deck-import a PowerPoint .pptx via the
# real PowerPoint app (RunDeckOps VBA macro), preserving per-slide backgrounds.
# See rules/deck-editing-rules.md. macOS + Microsoft PowerPoint only.
#
# Usage:
#   run-deck-ops.sh <basePath> <outPath> <importSpec> <orderStr> <replaceStr>
#
#   basePath    .pptx opened as the build container (output inherits its slide
#               size + masters). Use a UNIQUELY-NAMED copy — PowerPoint keys
#               open decks by filename, so base/import/output must not collide.
#   outPath     final destination (may be a Google Drive folder; see staging note)
#   importSpec  "" or "alias=/path[;alias2=/path2]" for cross-deck slide imports
#   orderStr    final slide sequence, e.g. "BASE:1 BASE:2 voxxed:13 BASE:49"
#               (token = <alias>:<1-based slide #>; alias BASE = basePath)
#   replaceStr  "" or "find=>to||find2=>to2" global text replacements
#
# Prerequisites: RunDeckOps.bas imported into an OPEN macro-enabled deck
# (e.g. DeckOps.pptm), VBA macros enabled, Automation consent granted once.
