1//! Bunny: a sitting rabbit on the app's 15 by 16 grid, drawn for the site. Long upright ears
2//! with a pink inside, a pear-shaped body (a narrow head over a wide lap), round dark eyes with
3//! a highlight, pink cheeks, a small split mouth, big hind feet and a round white tail. Cream on
4//! a dark page.
5//!
6//! Layout, back to front: tail, feet, ears, head and body, belly, cheeks, muzzle, eyes, mouth.
7//! The eyes are `Role::Eyes` groups so the gaze moves them; each blinks about its own middle.
