scripts/record-beat.sh

#!/usr/bin/env bash
# Record a single demo beat to its own .cap project.
# Reuses the same Chrome CDP window; starts/stops Cap per beat so each beat
# becomes a clean, short clip in Cap Studio.
#
# Usage from WSL inside chief-engineer/:
#   ./record-beat.sh load
#   ./record-beat.sh slice
#   ./record-beat.sh second
#   ./record-beat.sh scrub
#   ./record-beat.sh placement
#   ./record-beat.sh climb
#   ./record-beat.sh print
#   ./record-beat.sh review
#
# Requirements: Chrome + Cap + pnpm Playwright already set up (run ./record-studio.sh once).
