## Prompt that renders it frame-exact

Swap one block of text for another with Codrops' Text Block Transitions (demo https://tympanus.net/Development/TextBlockTransitions/, article https://tympanus.net/codrops/?p=72862, code https://github.com/codrops/TextBlockTransitions, MIT): twelve variations (js/demo1–12) split the paragraph into words or characters with Splitting.js and animate them out and the next text in with GSAP staggers (blur, slide, scale, colour flashes). Use it for a quote, a manifesto or a two-beat statement on a plain background. Each switchTexts() call builds a GSAP timeline; create it paused at the moment the text should change and seek it from the frame (HyperFrames: window.__timelines; Remotion: tl.seek(frame / fps)). Set the font size so the block fills about two thirds of the frame width.
