Highlight Fill

Paragraph words light up one by one as you read, with a marker highlight on key phrases.

Words split with SplitText, opacity scrubbed with stagger; highlights animate background-size.

Opacity only for words; background-size on a handful of <mark>s.

Text is always present and readable; reduced mode shows it fully lit.
