# probe-footage.sh — thin shim over _probe-footage-playwright.mjs; reached via
# `maude design probe-footage` (DDR-062), never a raw bin path. Extracts keyframe
# PNGs from one clip in headless Chromium for the footage-analyst's vision pass
# (feature-footage-analysis-director, Task 4). See the .mjs for the rationale.
#
# Usage:
#   probe-footage.sh <assets/<sha8>.<ext>> --root <repo> [--design-root .design]
#                    [--frames N] [--out-dir DIR]
#
# stdout on success = a JSON manifest { asset, durationSec, width, height, frames }.
# Exit: 0 ok · 2 usage · 3 no browser · 4 decode/probe error · 1 other.
