A claim brightens word-by-word as it's read — calm, editorial emphasis that guides the eye. On the live site this is tied to scroll position (scrubbed); here it loops so you can see the effect.

Copy is split into <span> words with incremental transition-delay; on the live site, scroll progress drives it.
Section intros, manifesto lines, pull-quotes.
