Strata is built for product launches and case studies where the camera does most of the talking. The hero pins for the length of the clip; scroll forward and the timeline advances, scroll back and it rewinds — no autoplay, no controls, no chrome.

Performance budget is honest. The clip is muted, preloaded, and encoded with frequent keyframes so seek is cheap. currentTime is lerped one frame at a time. On a 6-year-old laptop with the tab unfocused, this still holds 60 fps.
