Cascade Pitch CTA

A closing pitch that fits whoever is reading: pick 'designer', 'founder' or 'engineer' and the headline, the line under it and the button turn over letter by letter to new copy.

The prompt

The design brief behind this component — reuse it to regenerate, remix, or explain it.

Build a closing CTA with a small segmented choice above it — 'I'm a designer | founder | engineer' in a pill — and three versions of the pitch (headline, one line, button label). Choosing a role rewrites all three in place, letter by letter, like a departures board. Render each string as reels: one inline-block per character, exactly one line tall with overflow hidden, holding a two-row strip — the previous text's character at that index on top and the new character beneath. On change, every reel whose character differs plays a 620ms expo-out roll from translateY(0) to −50%, delayed by its index (11ms per letter in the headline, 4ms in the paragraph, 18ms on the button) so the change sweeps left to right. Unchanged letters stay still. Group the reels into the new text's words (nowrap) so lines only break at spaces; extra letters from a longer old string roll away out of flow. The roles are a radiogroup with roving tabindex and arrow keys. Each animated string is aria-hidden with the real text beside it in a visually hidden span, and a polite live region announces the new headline.

Notes

Interaction
Choose a role with a click or the arrow keys; the pitch turns over to match.
Motion
Each changed letter rolls in 620ms, staggered by position; the whole headline lands within about a second.
Accessibility
Real heading, paragraph and link carry the current text for screen readers; the reels are aria-hidden. The role picker is a labelled radiogroup, and the new headline is announced politely. Reduced motion swaps the text instantly.
Responsive
Fluid type with clamp(); words wrap only at spaces, so mid-word breaks can't happen during a roll.
On touch
Tap a role; everything else is the same.
