/*
DESIGN INTENT: JACKSON PORTER SCROLL-SEQUENCE VISUAL SYSTEM
What:  Defines one sticky viewport with three hard-cut video layers, responsive painting overlays,
       a Pretzel Regular identity wordmark, and the existing full-screen artwork record viewer.
Why:   Lets scroll position change only the active video frame while shot changes happen instantly
       and paintings remain the only saturated interface color over the nocturnal footage.
