## Prompt that renders it frame-exact

Introduce a person or a brand with Codrops' Intro Image Trail Animation (demo https://tympanus.net/Development/IntroTrailEffect/, article https://tympanus.net/codrops/?p=63293, code https://github.com/codrops/IntroTrailEffect, MIT): a stack of copies of one image moves as a trail while the two-line name above it splits up and down and the layout changes into a content page. The enter sequence is a GSAP timeline in src/js/index.js (showContent) started by the Enter button; build it paused and seek it from the frame (HyperFrames: window.__timelines; Remotion: tl.seek(frame / fps)). Use my portrait and name, and the dark warm background.
