Lazy Load Preview clip
A short UI-only capture tour for the Lazy Load intro clip, showing the below-the-fold image handoff before the full tour explains the real lazy-load setup.
Start on the eager hero image
Hold on the lead image first so the clip opens on the asset that should stay immediate instead of being deferred.
Move to the first lazy-loaded supporting image
Highlight the supporting image next so the clip clearly shifts from the eager lead visual to the image that can afford to wait.
Responsive lazy loading extends the same pattern
Highlight the responsive lazy image last so the clip shows that the same delay pattern can still choose different sources per viewport.
