Add the "Accordion Nested Tree" component from PixelPapa UI to this project.

What it is: A nested tree with indent guides where branches unfold with animated height and staggered children, fully navigable with the arrow keys.
Category: Accordions. Depends on: lucide-react, motion.

1. Install it with the shadcn CLI. It is a PixelPapa Pro component, so components.json needs the "@pixelpapa" registry with my API key (https://pixelpapa.com/docs/installation#pro):
   npx shadcn@latest add @pixelpapa/accordion-nested-tree
   (If the CLI is unavailable, fetch https://pixelpapa.com/r/accordion-nested-tree.json with the header "Authorization: Bearer $PIXELPAPA_API_KEY", write files[0].content to components/pixelpapa/accordion-nested-tree.tsx and install the listed dependencies.)
2. Import it from "@/components/pixelpapa/accordion-nested-tree" and place it where I describe below.
3. Keep its animation timings and accessibility attributes. Replace the demo copy and data with content that fits my product, and use my existing theme tokens (bg-background, text-foreground, bg-primary, border-border) rather than hard-coded colours.

Where to use it: <describe the page and position here>
