Hero Centered
A centred hero with an announcement pill, a headline whose lines rise out of their masks, one sentence and two pill buttons. CSS only, the entrance plays on load.
View codeA title sharp over a blurred picture. On scroll the focus moves to the picture, the title blurs and leaves, a readout counts the distance, then notes point out the details. It rewinds.

/* Kodza — Hero Focus
A big title, sharp, over a soft picture. On scroll the scene pins and the focus moves: the
picture sharpens and settles while the title passes the lens, blurs and leaves, and a readout
counts the distance like a lens ring. Once the picture is sharp the notes come by themselves,
one by one, on its details: a dot, a wire, a card. Each card finds a place that stays on screen.
Without the script nothing pins and the notes stay hidden: the title over the soft picture.
With reduced motion the scene pins, but the states swap at once.
Everything is tuned with the --kz-hero-focus-* variables. */

// Kodza — Hero Focus
// Plays the entrance once the section is in view (the label and title lines rise out of their
// masks, the picture opens from the top edge down while it settles), then hands over to the
// scroll: the scene pins and the focus moves from the words to the picture. The picture
// sharpens, the title passes the lens, blurs and leaves, and the readout counts the distance.
// Once the picture is sharp the notes come by themselves, one after the other: a dot on the
// detail, a wire, a card, each drawn at its own pace. A scroll that runs ahead of them hurries
// them, so they are drawn before the scene leaves. Scrolling back up closes them, the last one
// first, and plays the focus pull in reverse.
// "kodza:replay" plays the entrance again.
