## Features

- Character-by-character fill — each code line reveals left-to-right via a scaleX-animated child (transform only, GPU-composited)
- Staggered per-line typing that loops continuously with a hold, then resets and re-types
- Code-block layout — title bar with three window dots and a six-line code body with indented inner lines
- Click or press Enter/Space to replay the load-in animation
- All colors, spacing, and radii driven by design-system tokens (`--skel-line`, `--skel-peak`)
- Dark/light mode via the `body.dark` class
- Prefers-reduced-motion support (lines settle fully filled, no motion)
- Accessible: role=status, aria-busy, screen-reader loading label
