Chapter Pin

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/chapter-pin.tsx.

Install the pastetaste component "Chapter Pin" (chapter-pin) into this Next.js project and use it.

What it is: Scroll-driven story: a stage pins to the viewport while chapters of copy pass over it, and the stage receives scroll progress to animate anything.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/chapter-pin.json
   (it writes components/pastetaste/chapter-pin.tsx; install any npm packages it reports: motion@^12.23.0).
2. Import it: import { ChapterPin } from "@/components/pastetaste/chapter-pin" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It supports prefers-reduced-motion with a still state; do not remove it.

Props (all optional unless the type has no default):
- chapters: Chapter[] — Array of { label?, title, body? }; one slice of the scroll each.
- stage: (progress: MotionValue<number>) => ReactNode — Render prop for the pinned visual; receives smoothed progress 0 to 1.
- perChapter: string = '100vh' — Scroll length per chapter, any CSS length.
- align: 'left' | 'right' | 'center' = 'left' — Side of the viewport the copy sits on.
- className: string — Extra classes on the outer element.
- style: CSSProperties — Inline style overrides on the outer element.

Then run the dev server, check it in the browser at desktop and mobile width, and tell me the page URL.
