Invite-only sign-up, present mode, series, handouts, templates, dictation, progress, sharing

- Admin: sign-up Open / Invite only / Closed with single-use invite links
- Present mode for scripts (auto-scroll) and outlines (step through, pace vs planned minutes)
- Series: group studies on the dashboard, filter by series, calendar file for a study's sessions
- Lesson handout: printable page per session (passage, outline, questions, writing lines)
- Save a chunk's notes as your own study template (synced)
- Voice dictation for notes and scripts (browser speech recognition)
- Reading progress: map of the 66 books and a calendar of days read, synced and merged across devices
- Export highlights and bookmarks as Markdown or Word, grouped by named colour
- Verse of the day push to the ntfy topic (needs IQBIBLE_API_KEY)
- Sharing: co-teacher editing via single-use invite links; read-only links can expire and take a passcode
