Best practices for Velt View Analytics — the 'who viewed this document today' indicator with a count badge, recent-viewers dialog, and date- or user-aggregated subscriptions. Use whenever the user is adding the VeltViewAnalytics component, scoping it to a sub-document via type='location' + location-id, reading unique-view counts via the React hooks (useUniqueViewsByUser / useUniqueViewsByDate) or the non-React observable form (client.getViewsElement().getUniqueViewsByUser/ByDate().subscribe), building a custom trigger or viewer-list overlay via the velt-view-analytics-wireframe / velt-view-analytics-dialog-wireframe / velt-view-analytics-bottom-sheet-wireframe tags, or binding componentConfig.* template variables (todayViewsCount, totalUniqueViewsCount, treadsVisible, userViews, bottomSheetMode).

Package an existing talking-head / interview / podcast video by layering timed, designed GRAPHIC OVERLAY cards onto the playing video — titles, lower-thirds, data callouts, quotes, side panels, picture-in-picture — synced to the transcript. The source video plays in full; the agent designs and writes each card's HTML in conversation, then renders to MP4 via hyperframes. Use when the user asks for graphic overlays, on-screen graphics / lower-thirds / data callouts / kinetic titles on a video, "package / dress up my video", "add overlay cards / graphic cards", or AI-composed graphic packaging of an existing video. NOT for plain subtitles (→ embedded-captions) or building a video from scratch (→ the creation workflows); when unsure overlays-vs-captions, see /hyperframes-read-first.
