- sunrise_video.10s.sh: use $TIMEZONE (was hardcoded America/New_York), $SUNRISE_PRE_MIN/$SUNRISE_POST_MIN for capture window, $SUNRISE_TARGET_SECS for output duration (was wrong value 8 in a script named 10s) - fullday-video.sh: remove hardcoded FULLDAY_FPS/RETENTION_DAYS; both now come from sky-cam.conf - 4-seasons.sh, montage-mvt.sh: export TIMEZONE after sourcing conf so season_info.py subprocess picks it up via env rather than falling back to its hardcoded America/New_York default - sky-cam.conf: add SUNRISE_PRE_MIN, SUNRISE_POST_MIN, SUNRISE_TARGET_SECS, FULLDAY_FPS, RETENTION_DAYS https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
