Hardcoded crontab → render at container start from DIGEST_CRON_AM + DIGEST_CRON_PM. Defaults match the original 0800 / 2000 so existing deploys are no-ops. scripts/add-digest-user.sh learns --am and --pm flags so each teammate's stack can fire on their hours: scripts/add-digest-user.sh bob --am "0 6 * * *" --pm "0 17 * * *" scripts/add-digest-user.sh carol --pm "30 18 * * 1-5" # weekdays only Standard 5-field cron syntax; busybox crond honors the container's \$TZ. Removed the now-unused stacks/news-digest/crontab file and the matching COPY in the Dockerfile.
