## Features

- Nodes laid out in layers, each pulsing on a staggered delay
- Connections drawn as inline SVG lines that flash like signals
- Nodes tinted across the signature gradient by layer
- Design-system agnostic — node and line colors resolve from tokens
- Light theme by default with full dark-mode support
- Responsive layout that adapts spacing down to 480px
- Fully respects `prefers-reduced-motion`

## Accessibility

- **Loading role** — `role="status"` with `aria-label="Loading"` on the loader stage
- **Theme toggle** — `role="switch"` with `aria-checked` toggled by JS
- **Keyboard activation** — Theme toggle responds to Enter and Space
- **Focus indicators** — `:focus-visible` with a `--ring` outline on the toggle
- **Reduced motion** — `prefers-reduced-motion: reduce` disables all animations
- **Decorative SVG** — Background dot-grid layer marked `aria-hidden="true"`

## Keyboard shortcuts

- `Enter` — Activate the focused theme toggle
- `Space` — Activate the focused theme toggle
- `Tab` — Move focus to the theme toggle
