#
# Runnable on demand from the repo root. NOT a CI gate (single-shot
# artifact per REQ-372.8 / D-241). Asserts:
#   (a) source markdown exists
#   (b) slide count = 7
#   (c) per-slide speaker-note word counts in band
#       (1/2/4/6: 150-300; 3/5: 250-400; 7: 200-300)
#   (d) footer string present in source
#   (e) only S&P hex colors (#D6002A, #1B1B1B, #FFFFFF, #F0F0F0)
#   (f) rendered PPTX file exists
#
# Usage: bash scripts/check_leadership_deck.sh
# Returns: 0 on pass, 1 on fail.
