All green. You're good to build and deploy. Here's a summary of everything done since your last commit:

---

**🐛 Bugs fixed**
- Study hub/lesson pages turned gold — CSS merge error with `.study-index-page` fixed
- Lesson announcements not saving — `announcement` field missing from `sanitizeColossiansStudySections` whitelist
- 2FA email method blocked with "not configured" — guard checked `totpSecret` instead of `twoFaMethod`
- `STUDY_REMINDERS_FILE` constant never defined — server would crash on first reminder write
- `sanitizeStudyUsers` stripped all 2FA fields — data lost on every restart
- `scheduleStudyReminders` missing from refactored modules

**✨ Features added**
- Commentary supports paragraph formatting (double newline = new paragraph)
- Lesson announcement banner — full-width gold stripe at top of lesson page
- "Take the Quiz" renamed to "Discussion Questions" throughout
- Students must complete checkpoint before unlocking next lesson (lesson list + Next Lesson button both gate on it)
- No checkpoint questions → simple Mark as Completed button as fallback
- Truth For Life syndication widget on homepage
- Newsletter welcome email updated to your new HTML template

**🔧 Maintenance**
- `server.js` refactored from 6,013 lines into 12 focused modules
