The suntime library uses a simplified approximation that degrades at high
latitudes as sunrise approaches very early hours near the summer solstice.
The computed sunrise drifted progressively earlier than the actual event,
shrinking the capture window until today it ended before the sun rose.
Switch to skyfield's sunrise_sunset almanac (DE421 ephemeris), which is
accurate to within a second at any latitude — the same library already
used by moon_phase.py for sun events. The search window is anchored to
local midnight→midnight UTC so the correct calendar-day sunrise is
always returned regardless of timezone offset.
Also promote skyfield to the core pip install in bootstrap.sh (dropping
suntime, which is no longer needed) and tidy the stale "suntime" hints
in 4-seasons.sh and montage-mvt.sh error messages.

read_config / _read_conf now strips trailing inline shell comments
(whitespace + # + anything) before processing the value. Without this,
a line like:
SUNRISE_CAM=east # which camera faces east
produced SUNRISE_CAM = 'east # which camera faces east',
causing sunrise2mm.py to build a path with the comment embedded in it.
The regex \s+#.*$ requires at least one whitespace before # so passwords
or URLs containing # (e.g. %23 URL-encoded) are unaffected.

sky-cam.conf:
- MUSIC_DIR now uses override pattern (MUSIC_DIR="${MUSIC_DIR:-$SCRIPT_DIR/music}")
so the real path can be set in .env without hardcoding it
- LATITUDE/LONGITUDE use override pattern; set real coords in .env to keep
location private and out of git
- NTFY_URL now uses override pattern with empty default; set in .env
- NTFY_ENABLED moved out of comments into active config with false default
sunrise.py:
- Reads .env after sky-cam.conf so .env values override (same source order
as sky-cam.conf itself)
- Handles ${VAR:-default} bash syntax when parsing sky-cam.conf values
All completion notifications now include the full output file path so you
can tell at a glance where the file landed:
- daily_sunrise_video.sh: "filename — Xs, sunrise at HH:MM | /full/path"
- 4-seasons.sh: "filename — Xs | /full/path"
- montage-mvt.sh: "filename | checks | /full/path | verify: ..."
- year-end-join.sh: "filename — Xmin | /full/path" (also adds [cam] to title)
install.sh .env.example now includes LATITUDE, LONGITUDE, MUSIC_DIR, NTFY_URL
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
- chmod +x all *.sh and *.py in install.sh so permissions survive git checkouts
- Fix daily_sunrise_video.sh and Python scripts missing executable bit
- Add [CAM_NAME] prefix to all 4-seasons.sh notify.sh calls so multi-camera
setups show which camera each daily clip came from
- Include camera name in output filename: YYYY-MM-DD_<cam>_MvtN-DayXofY-final.mp4

daily_sunrise_video.sh: use \$MOVIES_DIR instead of \$BASE_DIR/movies so the
override in sky-cam.conf is respected when videos live on a separate drive.
capture.sh: default camera name falls back to \$SUNRISE_CAM (not the
undefined \$CAM_NAME) when no argument is passed.
sunrise2mm.py: also loads .env after sky-cam.conf so Mattermost credentials
moved to .env are actually visible to the upload script.
sunrise.py: raise a clear error message when LATITUDE/LONGITUDE/TIMEZONE
are missing from sky-cam.conf instead of an opaque KeyError.
4-seasons.sh, montage-mvt.sh: capture season_info.py output before eval so
a Python failure exits cleanly with a diagnostic message rather than
silently continuing with undefined variables.
bootstrap.sh: add system package install step (ffmpeg bc fonts-dejavu) and
show the .env setup step after install.sh generates .env.example.
README.md: correct Python package names and add fonts-dejavu dependency.

sunrise.py now reads LATITUDE, LONGITUDE, and TIMEZONE from sky-cam.conf
instead of hardcoded values, using the same pathlib-based pattern as
sunrise2mm.py. sky-cam.conf gains a comprehensive header with manual
systemd setup instructions and a full script map for future reference.
