System Alert

Install

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

Install the pastetaste component "System Alert" (system-alert) into this Next.js project and use it.

What it is: A scripted three-phase failure overlay (critical, rerouting, secure) with per-phase colour and progress, then a completion callback or a loop.

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/system-alert.json
   (it writes components/pastetaste/system-alert.tsx; install any npm packages it reports).
2. Import it: import { SystemAlert } from "@/components/pastetaste/system-alert" (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):
- phases: SystemAlertPhase[] = critical / rerouting / secure — { color, title, message, duration? } per phase.
- onDone: () => void — Called after the last phase.
- loop: boolean = false — Restart forever instead of finishing.
- fullscreen: boolean = false — Pin to the viewport instead of the nearest positioned parent.
- className: string — Extra classes on the root.
- style: CSSProperties — Inline style overrides.

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