Auto-detect SCRIPT_DIR/BASE_DIR; sunrise waits for capture window; optional overlay
sky-cam.conf: - SCRIPT_DIR auto-detects from its own location via BASH_SOURCE — no manual path entry needed after bootstrap; override still works via environment. - BASE_DIR defaults to \$SCRIPT_DIR/data; MOVIES_DIR defaults to \$BASE_DIR/movies. Override either to point at a drive/mount as before. - SCHEDULE_SUNRISE changed to 03:00 — the script now waits internally until the capture window closes before touching images, so the schedule just needs to be early enough, not timed exactly to sunrise. - Schedule section rewritten to explain what each job does and what day's data it processes (SEASONS/FULLDAY always process yesterday). - SUNRISE_PRE_MIN/POST_MIN comments explain the window and its relationship to SUNRISE_TARGET_SECS. - SUNRISE_OVERLAY_ENABLED=true added; set false to skip the timestamp entirely. daily_sunrise_video.sh: - After calculating the capture window, sleep until end_sec+30s if we fired before the window finished — guarantees all images are present. - DT (drawtext filter) is only built when SUNRISE_OVERLAY_ENABLED=true. - Step 3b skips ffmpeg entirely when overlay is disabled, moving work_video directly to final_video (faster, no re-encode). https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
