# verify-mvt.sh — review a completed movement montage and manage source JPEGs.
#
# Usage:
#   ./verify-mvt.sh <ASTRO_YEAR> <SEASON> <MVT_NUM> [CAM_NAME]
#
# Shows technical checks on the montage, lets you play it, then:
#   (p) play     — open in ffplay / mpv / vlc (whichever is available)
#   (g) good     — delete source JPEG folders for all movement days
#   (r) redo     — re-run music+overlay only (keeps sped file if present)
#   (R) redo-all — re-run full montage from daily clips
#   (q) quit     — exit without changes
