Previously sunrise-audio-capture.sh recorded the entire capture window (70+ minutes) and daily_sunrise_video.sh sought to the right position with a complex offset calculation. Now: record floor(TARGET/2) seconds before sunrise and ceil(TARGET/2) after — odd second goes to post-sunrise. The file is exactly SUNRISE_TARGET_SECS long and already centred, so no offset is needed when mixing. AUDIO_PRE_BUFFER_MIN removed — it was part of the old whole-window scheme and is no longer meaningful. https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
