- Notes: two-pane reader with searchable lesson list and snippets, track chips, friendlier empty states
- Reflection questions: numbered question cards, answered progress bar, unsaved-changes status, sticky save bar, share-to-discussion only when discussion is open
- Community: compact header, lesson browser sidebar with post counts (select on mobile), guidelines card, card-style posts
