Block Dissolve Reveal

Install

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

Install the pastetaste component "Block Dissolve Reveal" (block-dissolve-reveal) into this Next.js project and use it.

What it is: An image hidden under a canvas of square blocks that dissolve in random order when it scrolls into view, each flashing the accent colour before it clears.

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/block-dissolve-reveal.json
   (it writes components/pastetaste/block-dissolve-reveal.tsx; install any npm packages it reports).
2. Import it: import { BlockDissolveReveal } from "@/components/pastetaste/block-dissolve-reveal" (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):
- src / alt: string — The image.
- accent: string = '#e0261c' — Block colour just before it clears.
- cover: string = '#f1efe9' — Block colour before it flashes; match the page background.
- across: number = 16 — Blocks across the width.
- duration: number = 1500 — Whole dissolve in ms.
- threshold: number = 0.25 — Visible share that starts it.
- aspect: number = 1.5 — Width over height of the box.
- position: string — object-position of the image.
- replayKey: number = 0 — Change to run again.
- className / style: string / CSSProperties — On the root.

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