4-seasons.sh, fullday-video.sh: CAM_NAME fallback referenced undefined \$CAM_NAME — under set -euo pipefail this crashes if called manually without an argument. Changed to fall back to \$SUNRISE_CAM (matches capture.sh). daily_sunrise_video.sh: add log message when the capture window has already closed (manual re-run after the fact). Behaviour is unchanged — processing proceeds immediately — but the operator now gets a clear confirmation rather than silence. https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
