Step Reel

Install

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

Install the pastetaste component "Step Reel" (step-reel) into this Next.js project and use it.

What it is: An endless row of portrait cards that advances one card at a time: a sharp glide, a long soft landing, a short hold. Photos can cut to a new shot on each move. Caption bar, swipe, keys; pauses on hover.

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/step-reel.json
   (it writes components/pastetaste/step-reel.tsx; install any npm packages it reports).
2. Import it: import { StepReel } from "@/components/pastetaste/step-reel" (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):
- children: ReactNode — One child per card; each is stretched to the card size.
- interval: number = 1.5 — Seconds from the start of one step to the start of the next (glide plus hold).
- duration: number = 0.9 — Seconds the glide takes. Longer jumps (clicking a far card) take up to 1.6x.
- step: number = 1 — Cards moved per automatic step.
- direction: 'left' | 'right' = 'left' — Which way the row travels on its own.
- align / inset: 'center' | 'start' / string = 'center' / '0px' — Where the current card sits; inset is its distance from the start edge when aligned to the start.
- cardWidth / aspect / gap / radius: string = 'clamp(168px, 24vw, 340px)' / '4 / 5' / '14px' / '8px' — Card size and spacing as CSS values (also settable as --pt-reel-card, --pt-reel-ratio, --pt-reel-gap, --pt-reel-radius).
- autoPlay: boolean = true — Advance on its own. Off under reduced motion until the viewer presses play.
- pauseOnHover: boolean = true — Hold the current card while the mouse is over the row.
- controls: boolean = true — Bar under the row with the count, the caption and prev / pause / next buttons.
- caption: (index: number) => ReactNode — Caption for the current card, shown in the bar; it rises in as each step starts.
- onStep: (index: number) => void — Called when a step starts, with the index of the arriving card.
- startIndex: number = 0 — Card shown first.
- ease: [number, number, number, number] = [0.15, 0, 0, 1] — Glide easing as cubic-bezier points; the default was fitted to the reference reel.
- label: string = 'Carousel' — Accessible name of the carousel region.
- StepReelCut images / every / offset: (string | { src, alt })[] / number / number = — / 2 / 0 — Companion image for a card: hard-cuts to its next shot when the reel starts a step, every N steps; offset staggers neighbouring cards.
